Retail Data Analysis



Part I

Analytics play a pivotal role in the data flow scheme within a retail organization. A typical retailer generates more than thousands of data points through POS machine. It is difficult for a retailer to make strategic decisions based on this raw data.

A typical retailer has large amount of sales data stored in their systems. The new technologies have the ability to use these historical data to improve retail productivity. To create sustainable advantage over competition, retailers are trying to enhance their product offerings, service levels and pricing models. To prevent value attrition and to protect margins, retailers are trying to reduce their cost-to-serve per customer and thereby making sure that the total cost of ownership of a customer over time is reduced. Managing promotional plans is another critical area for retailers to focus on and target customers more effectively and efficiently.

Small and midsize retailers are facing problem with limited analytical resources to read the pulse of their business processes. Retailers are not able to follow up with day to day sales analysis, category analysis and brand share analysis for all the products.

Most retailers collect every transaction from every store, track every movement of goods and record every customer service interaction. Hence there is no shortage of data, but how does one translate all that data into actionable information? How this information can be used to make better decisions? The main objective of a retail store IT department is to convert the raw data into valuable and useful information.

Business analytics helps to get insights from the structured data, such as sales and productivity reporting, forecasting, inventory management, market basket analysis, product affinity, customer clustering, customer segmentation, identifying trend, identifying seasonality and understanding hidden patterns for loss prevention and store administration.

Analytical techniques such as statistical analysis, data analysis and analytical tools help in understanding patterns and trends within large databases. When we use them for creating analytical models, they provide the edge to decision making. While descriptive analysis helps to identify issues and examine causes, predictive analytics enhances the accuracy and effectiveness of decision making process.

Some analyses applicable to retailers are:

1. Reporting and Sales Analysis
2. Predictive Analysis
3. Inventory Management
4. Promotion-Effectiveness Analysis
5. Demand Forecasting
6. Brand and Category Analysis

Predictive analytics helps a retail organization to enhance its decision making powers by looking at the future with analytical rigidity. Predictive analytics holds the key to taking advantage of these opportunities such that retailers can increase their ability to forecast their customer’s behaviour and plan accordingly. Data analytics capabilities cover a number of possible analyses, using statistical software such as SPSS, SAS, Excel and Minitab.

Data analysis helps in decision making process with operational efficiency, saves costs by providing high quality solutions, facilitates flexible working models and state of the art data security. A well trained analytical team can help in the automation of data cleansing, processing and recurring reporting.

Part II

In the constantly changing competitive business environment, informed and intelligent decisions are the centre stage for every business organization. Data analytics and statistical techniques help to make business decisions and provide valuable insights to an organization.

Data Analytics is the science of playing with sales numbers to arrive at logical decisions by slicing and dicing the data to understand patterns and correlations that could give the company a competitive edge.

Retailers need to analyze various strategies surrounding merchandizing, pricing, promotion, markup and markdown to be able to make the right decision. Statistical and mathematical techniques are used to analyze current and historical data to make predictions about future events. The patterns found in historical and transactional data is used to identify risks and opportunities.

Data analytics gives a summary on top performers, bottom performers, key value items, sales performance, forecasting, trend and seasonality. Inventory management analysis helps a retailer to keep minimum inventory without running out of stock. Analytical team use the power of advanced statistical software, super computers and sophisticated mathematics to give actionable insights to the customer. Advanced mathematical techniques, formulas and statistical methods are used to predict the future demand of a product. This analysis considers the impact of holiday, seasonality and trend effect.

Retail data analysis helps a retailer to target their customers more effectively by campaigns, to improve response time to market changes, to increase employee productivity and to improve customer service at stores. Analytic models examine a customer’s recency, frequency and monetary value of customer visits along with purchase behaviour and provide a customer’s attrition probabilities on which retailers can take corrective action to reinforce loyalty. Some of the key analyses are:

o Customer profitability analysis
o Market basket analysis
o Opportunities for up selling or cross-selling
o Customer satisfaction analysis
o RFM Analysis

An analytical process can take care of data preparation, modelling activities and generates reports. Analytics provide actionable and powerful decision insights. These decisions are required for developing and maintaining profitable customer relationships. Retail reports give powerful insights and actionable analytics to the desks of retail managers and analysts in real time.

Data Collection Tools In Six Sigma



You can not imagine being able to organize the enormous amount of data and manipulate them as easily as you would be able to do without data collection tools. Then again, the task is not easily done unless you have selected the right kind of tool appropriate for the project. You need these data collection tools at all steps where you generate numerical data.

Six Sigma Data Collection Tools

The data collection tools are mostly in excel format and come as Macro Plug Ins, barring a few exceptions of stand-alone applications.

Initial Raw Data Collection Tools

1. Operational Definitions Sheet- This sheet defines the metrics so that data collection across the board is consistent.

2. Voice Of The Customer Data Collection Tool- Collect data from internal database, surveys, interviews, listening posts and observations at the point of sales and use and organize them systematically

3. Worksheet For Customer Segmentation- Worksheet for segmentation is essential to identify and concentrate on the demands of main and sub-segments which helps get down to finer details

4. Check Sheets- Very handy in collecting smaller sample data of different attributes or counts for use in defining problem areas or substantiating the outcomes.

5. Data sheets- These plain and simple datasheets are used to gather small amounts of measured or variable data to for the purpose of defining a problem or substantiating the results.

Data Assessment Tools

Data assessment tools are not decision-making tools such as the Ishikawa Fishbone Chart or the Thought Map Relation Diagram.

1. Customer Requirement Translation And Analysis Tool- Analysis of customer requirement is done to translate to an understandable and an unambiguous language. The translated and interpreted customer data converts into measurable functional requirements thus strengthening the operating team’s capability to deliver products and services that customers will immediately identify and really relish.

2. SIPOC Diagram- SIPOC diagram is rather a presentation diagram and an analysis tool at the same time. It provides an “at a glance” like overview of various processes, and helps identify the venders, inputs and outputs of a process and customers by critically contrasting the input data against each other

3. Pareto Chart- A Pareto chart is helpful in identifying those small numbers of problems which cause about 80% of all the troubles. This is a tremendous help in reducing or eliminating the avoidable waste of efforts so that you can channelize your improvement efforts on continuous productive applications.

4. Production Scheduling And Actual Scorecard- The simple production scheduling and actual score card comes handy to evaluate the production schedules and operations & sales planning as opposed to actual results. This is the same template which is used for Pareto chart, schedule to actual comparison and the checklist for quality.

5. QFD House Of Quality Chart- Quality Function deployment house of quality is an all in one tool. It helps identify customer requirements vis-a-vis products or services, develop an effective blueprint, formulate strategies to eliminate faults and failures and finally implement new design.

It would be futile to work without tools, either PC based or otherwise in a Six Sigma environment.

Data Management: Backup Strategies That Work



With cyber threats becoming a common phenomenon ensuring your data is safe and secure takes highest priority. With the right backup and recovery strategy in place you can make sure the information stored in your PC is kept private and well-protected.

Why Backup your Files
Backing up files is a virtual prerequisite to ensuring that any critical information remains secure in the event of a hard drive crash or a software failure. Duplicating important documents and media files can save a great deal of time and effort spent retrieving lost information. A number of PC mishaps that result in data loss ranging from hard drive corruption to unanticipated power shutdowns. Storing copies of files removes dependency on any one specific storage device while still allowing access to vital information when the primary memory is unavailable or non-functional.

Establish a Backup Plan
If data security is your prime concern, it makes sense to put in place an effective data backup schedule that will make sure you are able to manage a hardware crisis. To begin with, identify individual files to be duplicated such as sensitive business literature or media files including personal photos, videos and MP3. When relegating files to be copied, be sure to create a directory structure that is well-defined yet easily accessed. Establishing a backup routine involves making one-time copies of music files and photos, as also creating a schedule to duplicate files that are frequently modified. For instance, you may want to save business-related spreadsheets and reports or even backup work emails for reference at a later date. You could even copy zipped versions of software installation files, which can be particularly useful if you travel often.

Regular backups not only ensure that your data is maintained safe and sound, but makes scheduled duplication automatic using backup software. In addition you could even opt for off-site backups for a pre-negotiated fee, with several services online to choose from. In some cases, data loss can still happen in which case undelete software and recovery programs can come in handy.

Storage Options
There is no point in duplication done in the same disk drive, which makes external storage the most convenient choice. From CD Roms to DVDs and thumb drives, a range of options are available for the user to explore. External hard drives are the perfect backup accessory and are not only easy to tote around but offer significantly larger storage space. These devices are also more secure robust and come with other value-added features such as Bluetooth connectivity and Wi-Fi. Virtual storage is also gaining popularity with users choosing online cloud storage and file-sharing services to backup documents and media that are not particularly sensitive or private.

Storage tapes are the best option for users looking for consistent storage and a high level of security, although tapes can get quite pricey. A number of businesses even opt for additional reinforcements such as bank safes and fire-resistant storage units to maintain critical backups. Aside from onsite storage, off-site backup services abound in the market. Be sure to do your research right before investing in an online service, especially if data privacy is an issue.

Regardless of the backup procedure you choose, a consistent data backup routine can ensure that important files are well-preserved for enhanced ease of access.
