Using Data Science and ML In Zomato To Guarantee Customer Satisfaction

According to a report, India's online food delivery sector is anticipated to reach $4 billion. Before 2010, ordering takeout for delivery at home required calling the establishment.

This growth is expected due to rising smartphone usage, an expanding e-commerce market, a growing number of young people entering the workforce, and rising internet penetration.

But how does zomato manage all its operations to guarantee customer satisfaction? 

Data science has become the key! 

In 2015, Zomato began using data science techniques to improve its services. They created algorithms that could recommend places based on user preferences and past actions taken by users on the site. This allowed them to create more accurate search results than before.

The ability to interpret, analyze and interpret the insights gained from data is one of the most important concerning business growth in the current era. The ability to understand where change is happening in your industry and how it varies between different areas will help you reach new customers and improve your conversion rates. 

In this blog post, I would like to share some insights into how Zomato uses Data Science for its business.

Data Science

Data science is collecting and analyzing data to develop a computer model or algorithm for making decisions about the future. It can also be used to predict outcomes based on past data. Data scientists use a variety of techniques, including statistics and machine learning.

About Zomato 

Zomato is a restaurant search service that allows users to find restaurants and other types of businesses. Zomato was founded in 2010 by Deepinder Goyal and Pankaj Chaddah. It began as a website that allowed people to search for restaurants and other types of businesses using keywords or tags. The company's mission is to help people find the best food, drink, and entertainment near them.

Zomato now uses machine learning algorithms that are trained on billions of data points about what customers want when searching for restaurants. These algorithms aim not only to let people find restaurants but also to provide them with information about what kinds of foods they might like at those places, so they can make better decisions when going into different eateries.

The Zomato ML team emphasizes image processing and NLP-based review extraction to improve product optimization, create recommendation engines, and implement features that enhance the operational elements of the sector. Predictions are generated using this interface once the machine learning model has been deployed, which produces a server to do so using APIs. For more information on NLP and other ML techniques, visit the IBM data science course in Chennai, and learn the concepts in detail. 

How data science assists zomato? 

Initially, image processing and NLP evaluations were used to moderate user-generated content. This gradually expanded to cover things like product optimization, recommendation engines, and feature upgrades and is now extended to business and operational parts of the organization.

Today, to provide customers with personalized experiences, we need to be aware of their preferences in real-time. Zomato is investigating machine learning methods to handle issues like food delivery, allocating the best partners for delivery, food preparation time, etc. This raises revenue, boosts the company, and promotes consumer satisfaction.

To improve customer service through predictive analytics, zomato uses machine learning models to predict when customers will be unsatisfied with their meals and provide customer support at that time. 

The specific models used depend on the type of restaurant being reviewed, but all models are trained using historical data from other customers' experiences with each restaurant type (i.e., they are predicting how likely someone is to have an unsatisfactory experience based on previous data).

Use of Big data in Zomato

Enhancing the menu using big data 

With Big Data solutions at their disposal, their meal delivery software may collect client input regarding the items on the menu of many registered eateries.

The restaurants can then receive recommendations from the system regarding menu items that will help them generate more business. Restaurants can increase their operational efficiency by changing menu items. By doing this, they can increase the promotions they run on popular goods and increase sales.

2. Faster Deliveries

Fast delivery times are the most prominent of the many elements contributing to food technology firms' success. Compared to its rivals, a meal delivery service will do better if it provides users with faster delivery times. Though it might seem straightforward, numerous challenges must be overcome to transport freshly prepared food from restaurants and deliver it to the customers. With Big Data Analytics systems, they can keep an eye on various factors, including traffic, weather, and roadblocks along the route, and provide the shortest route to ensure that the food is delivered as quickly as possible.

3. Customer Sentiment analysis

You cannot afford to ignore customer feedback on social media in the modern world, where social media is a key factor in determining an app's success or failure. Companies that have Big Data technologies can determine how customers feel about their brand.

Questions such as: 

1. Do your delivery boys bring the food on time? 

2. Are your customers satisfied with the performance as a whole? 

3 Are your efforts having an impact? 

After looking at every business mentioned on every social media platform, including Facebook, Twitter, Instagram, and Linked In, you can find the answers to all of these questions. The food-tech sector is currently using this data to inform commercial decisions.

Conclusion

A large amount of data is available in Zomato, and this big data is not just a source of value but also could prove harmful if its vulnerabilities are not addressed on time. The Data Science team at zomato ensures that the security and privacy of user data are controlled and hacking attempts are prevented. Through various operational checks, they optimize the data flow while deriving insights and derive performance reports that help the research and product teams take business decisions quickly. Furthermore, this group also monitors anomalies in traffic which helps prevent hackers from entering via compromised accounts.

Overall, data Science is very relevant to the business of Zomato. Zomato constantly strives to improve its data science processes and its product. Through a combination of machine learning, natural language processing and data visualization tools, data scientists have gained valuable insights into customer acquisition and retention. If you want to master data science and ML techniques, join the job-ready machine learning course in chennai right away and get ready to make great contributions to firms like Zomato!

8 Powerful Data Cleaning Techniques for Better Data

We all know that data is messy and difficult to manage. Data cleaning techniques are part of a data-driven approach to improve value for our customers, reduce costs and even increase revenue.  Cleaning up and managing the data in your business is a daily activity that can help boost performance, increase accuracy, and improve results. But how do you know whether your cleaning practices are effective? Where should you start, and which techniques should you use in your particular situation?

In this article, we will discuss some effective data-cleaning techniques that can be used to improve the quality of your business’s performance.

What is Data Cleaning?

Data cleansing is a process to improve the quality of data before it gets to your application and business. In other words, data cleansing is the process of cleaning dirty data. Data cleanup can be applied manually as well as automatically, depending on your purpose.

Importance of data cleaning

You can complete your analysis much more quickly if you start with clean data that are free of erroneous and inconsistent values. By completing this task ahead of time, you would save a lot of time. You could stop many errors by cleaning your data before using it. Your results won't be accurate if you use data with false values. Data purification and cleaning take up a lot more time for a data scientist than data analysis. 

Efficiency

Identifying data Quality

Accuracy

 Error Margin 

Consistency

Uniformity 

Effective Data Cleaning Techniques

The first step to cleaning your data is to understand what types of data you have. Once you know this, you can determine what types of tools are best suited for the job. 

You can also select specific values from within each row or column and then export them as text files to create a list of all the data elements that need cleaning up. This is useful when working with large amounts of information because it allows you to see exactly what needs fixing before moving forward with any further steps in order

1. Remove Duplicate Data

Duplicate data is a problem that can be solved easily. In fact, it can be done manually or automatically and the results are almost the same. The first step in removing duplicate data is to identify all duplicate records in your database. Next, you need to merge these records into one record. There are two different methods that you can use for merging records: 

Merge by Right-Clicking/Ctrl+Click

Merge by Using an Excel Add-In

A detailed explanation of data cleaning techniques can be found via the best data science course in Chennai, designed in collaboration with IBM.

 2. Remove irrelevant data

Any analysis you attempt to conduct will be complicated and slowed down by irrelevant data. Deciding what information is relevant and what is not is therefore necessary before you start your data cleaning. You don't have to include their email addresses, for example, if you are analyzing the age range of your customers.

You should also eliminate the following components because they don't add anything to your data:

URLs

HTML tags

Tracking codes

Personal Identifiable (PI)

Blank space between text

3. Remove Nulls

Nulls should be eliminated as well, as they can cause problems when they are used in arithmetic operations or comparisons. You can do this by using a unique index on the column containing the null values and using a WHERE clause to remove them from your data set.

4. Convert data types

The most typical type of data that needs to be converted when cleaning your data is a number. However, they must appear as numerals to be processed. Numbers are frequently imputed as text.

They are classified as a string if they appear as text, which prevents your analysis algorithms from solving mathematical equations on them.

Likewise, dates that are saved as text are accurate. Make them all numerals, please. For instance, you must change entries to read 09/24/2022, if they currently say September 24th, 2022.

5. Clear Formatting

Your information cannot be processed by machine learning models if it is heavily formatted. Different document formats are probably present if you are using data from a variety of sources. Your data may become muddled and inaccurate as a result.

To start over, you should eliminate any formatting that has been applied to your documents. This is typically not a challenging process; for instance, standardization functions are available in both Google Sheets and Excel.

6. Handle missing values

There would always be some information lacking. It's unavoidable. In order to keep your data accurate and clean, you should be aware of how to handle them. Your dataset might contain too many missing values in one particular column.

In that case, since there isn't enough information to work with, it would be prudent to remove the entire column.

Thus, you should never ignore missing values. 

If the missing value is completely removed, your data can now no longer contain insightful information. After all, there was a reason why you initially wanted to gather this information.

Hence, it might be preferable to fill in the missing data by doing the necessary research. You could use the word missing in its place if you have no idea what it is. You can enter a zero in the blank field if it is numerical.

However, you should remove the entire section if there are so many missing values that there isn't enough data to use.

7 Fix the errors 

You should obviously take care to rectify any errors in your data before using it. You might miss out on important data findings if you make mistakes as simple as typos. With something as simple as a quick spell check, some of these can be avoided.

You might miss out on communicating with your customers because of misspellings or extra punctuation in data like an email address. It might also cause you to send unsolicited emails to recipients who have not requested them.

Inconsistency in formatting is another type of error. To maintain a consistent standard currency, for instance, if you have a column of US dollar amounts, you must convert any other currency type into US dollars.

8. Language Translation 

You need everything to be in the same language to have reliable data.

Software used to analyze data typically uses monolingual Natural Language Processing (NLP) models, which are unable to process multiple languages. Therefore, you must translate everything into a single language.

Summary

To sum up, the best way to go about cleaning data is always dependent on the problem you are trying to solve. The time required for data cleaning will always depend on the data itself, and if any anomalies need to be resolved.

This article is written based on the knowledge of data cleaning techniques applied by experienced professionals. However, you can apply these tips at home to clean your own data, or to help you get a better feel for how much cleaning is needed in your own data before processing or loading it. In the end, invest a little time applying these tips and you'll be rewarded with higher-quality records.

These two terms provide information about a person or group of people to make decisions on what they need. Data science helps in understanding customer needs by collecting data from different sources and analyzing it using computer algorithms. Analytics helps determine what customers want most by analyzing their needs and behaviors. 5 Ways Data Science Is Changing The Insurance Sector

Insurance companies have recently realized the impact of data science and analytics on their bottom line. They are now investing in technology that will help them reduce costs, increase revenue and improve customer satisfaction.

In the insurance industry, data science and analytics play an important role in providing better customer service. These two terms provide information about a person or group of people to make decisions on what they need. Data science helps in understanding customer needs by collecting data from different sources and analyzing it using computer algorithms. Analytics helps determine what customers want most by analyzing their needs and behaviors.

Data science and analytics in Insurance 

The use of data science and analytics in Insurance can be divided into three categories: predictive modeling, descriptive, and prescriptive modeling. 

1. Insurers use predictive modeling to identify potential risks on actuarial grounds that may lead to loss or damage for their clients through statistical techniques such as regression analysis or neural networks. 

2. Descriptive modeling involves using historical data to describe past events (such as claims rates) or trends (such as claims patterns). 

3. Prescriptive modeling involves using predictive models to make recommendations about managing risks based on what happened in the past. For detailed understanding of these concepts, refer to the data science course in Chennai, accredited by IBM. 

4. Insurance is a complicated business, and it would be effective to use data science to improve the efficiency and profitability of the insurance industry. The following are some of the applications of data science applied in the insurance industry.

1. Automated Insurance Fraud Detection

Detecting fraud is not only necessary for avoiding financial losses but also a valuable contribution to society in general. Nonetheless, some insurers continue to depend only on the claims adjuster's gut instinct for fraud detection, resulting in unreasonably high expenses. With the emergence of big data and increasing access to third-party data to supplement investigations, it is time to shift away from the claims adjuster's gut feeling and toward a more data-driven approach, not to mention the enormous time savings and process optimization advantages.

Fraud detection tools identify fraudulent activities, suspicious relationships, and subtle behavioral patterns using various techniques such as text mining and image screening.

A constant stream of data must be provided to the algorithms in order for them to detect fraud automatically. This information is either from internal records of prior occurrences of fraudulent conduct or from external fraud pools that have been analyzed using sampling methods.

Predictive modeling methods are also used in this case for fraud analysis and filtering. Identifying linkages between suspicious actions aid in the detection of previously undiscovered fraud schemes. In the end, insurers who use these platforms will significantly reduce the number of false claims, resulting in huge savings

2. Healthcare Insurance 

The practice of health insurance is commonplace worldwide. The costs associated with a disease, an accident, a disability, or death are typically covered. Governments in many nations have been vocal supporters of healthcare insurance policies.

The influence of data analytics applications is unavoidable in the era of rapid digital information flows in this area. The market for healthcare analytics is expanding rapidly on a global scale. The insurance industry is under constant pressure to deliver better services while lowering costs.

For the healthcare insurance industry, various data are gathered, organized, processed, and transformed into insightful knowledge. These data include insurance claims data, membership and provider data, benefits and medical records, consumer and case data, internet data, etc. As a result, factors like cost savings, healthcare quality, fraud detection and prevention, and consumer engagement may all significantly improve.

1. Customer Lifetime Value (CLV)

Customers' lifetime value (CLV) is a complicated concept that expresses how valuable a customer is to a business as the difference between revenues earned and expenses incurred throughout the entire future relationship with the customer.

Customer behavior data is typically used to estimate the CLV and forecast the customer's profitability for the insurer. The behavior-based models are thus frequently used to predict cross-selling and retention.

Recency, the financial value of a customer to a business, and frequency are considered crucial variables when estimating future earnings. In order to create the prediction, the algorithms gather and process all the data.

This makes it possible to predict whether customers will maintain their policies or cancel them based on their behavior and attitudes. The CLV prediction may also help develop marketing strategies because it puts customer insights at your disposal.

2. Automated Risk Assessment

An automated risk assessment tool enables you to get to know your customer (KYC), do thorough customer due diligence, and evaluate the risk a customer needs to cover. Adopting risk assessment techniques in the insurance sector ensures risk prediction and reduces it to the bare minimum to reduce losses.

Proper risk analysis takes time for insurers as you have to consider what to cover and who you are insuring.

An automated risk analysis tool allows you to gain real-time access to internal and external data. The risk assessment tool assists you in making quick decisions based on your appetite for risk and data. This accelerates your digitalization and improves the customer experience because the consumer can determine whether or not the insurance policy has already been authorized in seconds.

3. Claims Automation

Claims automation systems offer one of the biggest options for insurers to position themselves from the market and engage their customers for a lifetime.

Claims automation technologies can assist insurers in optimizing claim workflows from the initial report of loss through settlement, saving time and building stronger relationships with policyholders. 

P&C insurers place a high priority on determining damage estimates for a specific claim. The evaluation is frequently based on information gleaned from various sources, including emails and other paper-based or PDF formats, such as damage predictions or police reports. In such instances, an AI algorithm may be trained to extract the relevant data from each document reliably. 

Once the claim information is structured, it can be analyzed using robotic process automation (RPA) and artificial intelligence (AI). It decides whether or not the insured has enough coverage. If a claim is evaluated and determined to be low risk, it may be allowed for instant payout or triaged to an adjuster if it is more complex. If a high-risk claim is found, it is forwarded to a special investigative unit for additional review.

Data Analytics in Insurance – The Future Implication

The insurance industry is adopting data-driven models and machine learning techniques to better manage risk and to create products by analyzing massive amounts of data. Overall, the insurance industry is one of the best industries for using predictive analytics and data science as there is plenty of information available about insurance history. This will help improve their profits, reduce wastage in each operation, and increase their client's success rate by getting predictions about the right customers using analytical tools like logistic regressions and decision trees.

If you're from a finance background and looking to move your career in data science, you can sign up for the best data science courses in chennai and become a certified data scientist or financial analyst.

What Is HR Analytics?

HR analytics uses data to improve your company's operations and increase its bottom line. It gives you insights into everything from employee satisfaction to turnover rates to productivity trends, allowing you to make informed decisions about how best to run your business.

Application of HR analytics

Employee training is another topic where data science can help improve existing evaluations. For example, data analysis can determine which courses have previously been shown to be most beneficial to employees in later performance reviews. This crucial workflow can also be made better through the use of technology and analytics. Recruitment is another field that makes use of data science to empower hiring managers to define their ideal candidate through applicant tracking systems, social networking sites, market analysis, and applicant review assessments. This will result in a more appreciable recruitment process for both the hiring manager and applicants.

People analytics, workforce analytics, and talent analytics are all covered in HR analytics. These analytics components serve different human resource activities by automating and making them more cost-effective over time.

1. Attendance

2. Employee surveys

3. Salary and remuneration

4. Appraisal and Promotion 

5. Work history of the employee

6. Past database of employees

This information is gathered and simplified for improved strategic decision-making and human resource planning. Data may also aid in greater alignment and coordination among the organization's various departments. Furthermore, the HR software may be upgraded to deal with employee and manager issues.

The top applications of data science in HR are as follows;

1. Workforce analytics  

Data science, by thoroughly analyzing the corporate workforce, enables HR management professionals to grasp the major demands of their firm better and properly monitor critical parameters. HR professionals might locate and hire suitable professionals quicker and directly influence a company's overall performance by properly knowing which candidate's traits are the most beneficial to the company's objectives.

2. Talent analytics

That's where data science can be beneficial. It facilitates the smart structuring of convenient talents, improving current training programs, evaluating attrition, and perfecting recruitment methods to ensure a high level of staff retention. Data science can drastically revolutionize the whole HR sector by eliminating outdated methods of assessing HR metrics and providing firms with insights they would never have obtained from traditional surveys or candidate interviews.

3. Employee Performance  

Analyzing and measuring employee performance is critical for obtaining a more accurate employee assessment report. Greater analytics may help organizations retain talented and experienced personnel while also providing better employee growth. Analytics may assist in identifying the organization's best and underperforming performers, determining the average length of employment, motivating elements for employees, and so on. This will improve career advancement decisions, enhance employee happiness, identify leadership skills, and motivate them to improve overall performance. As a result, analyzing employee performance will enable the firm to enhance its overall ROI and identify prospective leaders.

4. Training and development 

Many organizations confront the challenge of a skills mismatch. Thus, most employees lack the necessary skills to perform various tasks. In-house training is also in high demand because there is always a shortage of adequate skills in entry-level professions. HR analytics can assist in more efficiently bridging that gap. It can aid in collecting data about employees and their level of expertise to determine how they can be taught. Analytics may also assist in directing resources to the appropriate locations for staff training and in reviewing the overall development process. This will help companies in making their personnel more qualified and competent, which will not only improve corporate performance but also provide a competitive advantage.

5. Employee Retention 

One significant benefit of adopting HR Analytics and having a data scientist on the HR team is the potential to identify why people leave and remain. HR can essentially forecast (and hence avoid) employee attrition by evaluating data from techniques like employee satisfaction surveys, team evaluations, social media, and leave and stay interviews, among others.

Data science specialists could also assist the HR team in identifying issues that contribute to low employee engagement and chances to increase engagement, resulting in a more successful workforce. 

For example, suppose an organization has been experiencing high turnover rates among salespeople. In that case, they could use predictive analytics tools like machine learning algorithms to find out why this is happening—and design strategies to prevent it from happening again.

Summary 

As you can see, the world is rapidly moving towards digitalization, which has revolutionized several industries in many ways. HR Analytics is one such industry that has undergone a lot of changes, especially with the wide range of advanced data science techniques present to help businesses take important, data-driven decisions regarding their staff requirements.

When you think of big data architecture, you may think of big servers and complex software systems. Right? But big data architecture is actually much simpler than that. It's all about getting the right balance between storage units and file systems, so your data is stored effectively, allowing for fast retrieval and keeping it secure from malicious users and hackers.

Big Data has become a new field of research and application in the last few years. As Data volume, velocity, variety, and value keep growing exponentially; we must ensure we can handle them all effectively. This article will provide you with an overview of big data architecture.

What is Big Data Architecture? 

Big data architecture is the process of designing, developing, and deploying solutions that utilize a wide range of data sources. It's essential to understand how to create a big data architecture to use your data in the most efficient way possible. 

But why is it so important? 

Suppose you're analyzing something that has nothing to do with statistics or machine learning, like how many people buy one specific product at a particular retailer each year. Well, you'll need an entirely different type of architecture than if you were analyzing something like clickstreams worldwide!

1. Data sources — These are the data sources that your business uses to generate insights and make decisions. For example, if you own a car repair shop, you may access vehicle information such as mileage, when it was purchased or serviced, and its maintenance history. This information would be considered a "source" of information because it's used by the business itself to make important decisions about how people should be treated when they visit your store for repairs.

2. Data stores — These are physical locations where your organization stores its data. Today's most common database organizations use relational databases such as MySQL (MySQL) or PostgreSQL (PostgreSQL). Others include NoSQL databases such as MongoDB (MongoDB), Cassandra (Cassandra), Couchbase (Couchbase), Redis (Redis), etc.

3. Data processing pipelines: This refers specifically to how you use these different types of

There are three major categories of big data architecture:

Distributed Storage 

This type of architecture uses multiple servers to store the data. It provides fault tolerance and high availability because it distributes the load across multiple servers, which can be located in different locations. However, this approach can be costly due to the additional hardware costs involved with establishing other servers.

2. Hierarchical Storage

This type of architecture uses one or more central servers to store the information and then distributes queries through these servers in a round-robin fashion until they reach their destination server. This approach is often used when extensive datasets must be searched through without having access to each individual record (for example, when searching for a specific piece of information within a database).3. Columnar Storage

This type of architecture stores each record as a single flat file rather than using relational databases like MySQL or Oracle's In Big data architecture is a framework for designing an organization's data-centric information architecture. Big data architecture aims to establish a system that can efficiently handle the processing and storage of large amounts of data while also improving the overall business value.

Benefits of big data architecture

High-Performance parallel computing 

Big data architectures use parallel computing, wherein multiprocessor servers conduct several calculations simultaneously to accelerate the process. By parallelizing large data sets on multiprocessor computers, large data sets can be processed quickly. Part of the job can be completed concurrently.

Elastic scalability 

Big Data architectures allow for horizontal scaling, which enables the environment to be adapted to the magnitude of the workloads.

Big data solutions are typically run in the cloud, where you only pay for the processing and storage power you use.

Freedom of Choice

Big Data architectures can use various commercially available platforms and products, including Apache technologies, MongoDB Atlas, and Azure-managed services. You can choose the best combination of solutions for your unique workloads, installed systems, and IT expertise levels to get the best outcome.

The ability to interoperate with other systems 

To build integrated platforms for various workloads, you can leverage Big Data architecture components for IoT processing, BI, and analytics workflows.

Applications of big data architectures

Different big data architecture layers

The four logical layers that perform the four fundamental activities make up most of the big data analytics architecture components. The layers serve only as an analytic organization tool for the architecture's parts.

1. Big Data source layer – The sources and formats of the data that can be analyzed will differ. The format could be structured, unstructured, or semi-structured; the speed of data arrival and delivery will vary depending on the source; the method of data collection may be direct or through data providers; batch mode or real-time; and the location of the data source may be internal or external to the organization.

2. Data massaging and storage layer — This layer gathers information from the data sources, transforms it, and stores it in a format that data analytics programs can use. Governance policies and compliance standards generally determine the most appropriate storage format for various data types.

3. Analysis layer – To gain insights from the data, it collects the data from the data massaging and storage layer (or straight from the data source).

4. Consumption layer – This layer accepts the output from the analysis layer and presents it to the appropriate output layer. The output's consumers could be people, business processes, visualization software, or services.

Applications of big data architectures

Using and implementing big data applications is vital to big data architecture. In particular, the following big data applications are used and applied by the big data architecture:

. Due to its data ingestion process and data lake storage, the big data architecture's structure enables the deletion of sensitive data from the beginning.

A big data architecture involving batch or real-time ingests data in both formats. There is a regular schedule and frequency for batch processing. 

Data from the table is divided using SQL, U-SQL, or Hive queries. By splitting the tables, the query performance is enhanced. Since data files can be segmented, the ingestion process and job scheduling for batch data are more straightforward.

Distributed batch files can be further divided using parallelism and quicker work times. Workload allocation across processing units is also employed.

The static batch files are built and saved in further-splittable file formats. The formats used to create and store the static batch files might be further divided. The Hadoop Distributed File System (HDFS) can process files simultaneously across hundreds of nodes, reducing job times over time. The Hadoop Distributed File System (HDFS) may group hundreds of nodes and process files in parallel, thus reducing job times.

Conclusion

It is important to understand the different components of big data architecture and how each of the components can impact a big data strategy. With a proper understanding of big data architecture, companies can prepare to handle structured and unstructured data. It helps them make strategic decisions about what actions they should take with those data sets.

High-quality data is key to most business models, and the importance of this point cannot be overstated. It's interesting to note that Amazon is already in the big data space (via AWS). They will likely continue to drive innovation here and ultimately gain a significant market share.
