Project: CapOne Merchant Partner Conversions(RPM/WSI/Ridge/BB) As part of the project, set of raw source files containing the customer demographics, human data, NPI, PCI, income, credit worthiness data, events, transactions, statements, Offer, etc. were processed using Ab Initio, Spark, Scala and Databricks. The processing involved decrypting/converting the files and tokenizing them using Ab Initio and Spark scala codes. For further downstream processing the tokenized files were processed through the implemented business rules in Ab Initio Conduct IT plans, psets, graphs and were used to create the LR files using Databricks. Those LR files were then shared with TSYS, who in turn generated a new set of Day0 files for CapOne. Those Day0 files were then processed through Ab Initio conversion plans, pset and graphs setup as workflows and jobs on Automic Scheduler to go through the business rules and generate the LR files on AWS S3 buckets for downstream teams and to also load into Snowflake database and created Views for various applications and user teams.

Project: Cheers Ratesheets Conversion to Ab Initio As part of the MF conversion program, FedEx converted the Cheers rate sheets generation process to Abinitio processes. Cheers rate sheets generated current and proposed rates for letter, pak, service and heavy weight package types for the current and proposed proposals sent by the EPRS users. In order to generate those rates the new programs process the messages through Ab Initio continuous flow graphs received from the Java application Xopco, pull data from different EDD tables and IMS databases that were converted to Ab Initio ICFF, process data collected from multiple Ambassador services using Abinitio continuous flows, pull data from multiple SSI files and internal db at various stages of the program flows to be processed by the complex set of program rules implemented in multiple Conduct It plans, psets, graphs and micrographs. Apart from different types of rates, the ratesheets also contain zone chart information if the user requested for it. Rate Sheets can be of different types like, Non-US Intra, Import, Export, Inbound, L3P and G3P, depending on the need of the business and the users, for each kind a different set of Ab Initio process was designed and developed.

Project: Streamlining ID Data Integration

This project was executed to streamline the delivery of information from the CIL layer to various downstream consumers. It was a Technical Implementation project and the aim was to revise the design of the old data flow architecture from CIL to the downstream consumers, which was flawed with data losses in the MQ channels, delays in data deliveries and in some places absence of adequate checks and balances. Some of the changes implemented as part of this project were switching the data staging layer from MQ to soft links, implementation of checks and balances, smart reading/archiving/deleting of the soft links in Ab Initio.

Project: Enhancements and Incident Fixes in Commission application of Blue Cross This project was part of an Enterprise Initiative that was run by Blue Cross to fix all gaps and data issues that had accumulated over the span of couple years since the Enrollment, Product, Producer, Delinquency and Income data of Blue Cross was migrated to Facets. Because of the out of sync old Commission application process and the accumulated data issues the data coming out of the Commission app was down to 40% accuracy rate, which was resulting in faulty Commission payments to the Producers and was also creating a lot of manual work for business users. To improve the data accuracy, all the Enrollment, Product, Producer, Delinquency and Income data coming from the Facets system was thoroughly analyzed along with the old business rules implemented in Commission application and then a series of enhancements and fixes were implemented in Ab Initio processes. That resulted in the improvement of data accuracy from 40% to more than 98% rate, which significantly reduced the faulty Commission payment and manual work for Business users.

Project: Provider Information Management System (PIMS) The project is aimed to integrate McKesson application PIMS into provider management processes of BCBSNC. After integration PIMS a Provider Information Management System application would be used by BCBSNC to store & process updates related to Business Entities, Providers, Practitioners, their locations, specialties, affiliations & networks. Updates fed through PIMS would be provided to downstream applications such as PMHS, NTS & EDW. This project involves a one-time setup of PIMS Data Warehouse, which would house all the necessary information for Business Entities, Provider, Practitioners, etc. This information is extracted from the currently operational sources such as PMHS, Blue Provider & NTS. This one time setup would be done with the help of Ab Initio, Unix & Pl/Sql. Project also involves creation of an adapter that would process daily updates to downstream applications such as PMHS, Blue Provider & NTS, after the Data Warehouse is ready and PIMS application is live in the production environment.

Project: Planogram – Item Shelf Min Override

In the existing Walgreen’s system, the Minimum Shelf Quantity for an Item at a Store is calculated based on the variable, store, BDM shelf min, corporate overrides and based on the item setup in planograms. Walgreens decided to change the current system in order to provide the screens to override Minimum shelf quantity by entering the specific WIC, planogram. The Shelf Min Qty Override at Planogram-Item level would affect the process of calculating the Total Min Shelf Qty for its Controlling Item at the store. Hence the Item Shelf Min process was to be changed to recalculate the Min Shelf Qty for a Controlling Item at a store if there is a Min shelf Qty override for its Item-Planogram. All this was being done in order to come up with the most optimum value of the shelf quantity for an Item at the Walgreens stores which in turn would directly impact the overall profit margin.

Project: Multi-sourcing FoRS Impacts

Walgreen wanted to implement a vendor multi-sourcing strategy for their items across all stores. In this strategy there are multiple vendors that compete to get the orders for a single Walgreen item. Different vendors may offer different deals, discounts or bonuses to get the orders for the item. Walgreen would then choose the most profitable offer and the contract for supplying the item would go to the vendor giving the offer. In order to implement the strategy the functional processes creating order forecast for Walgreen items had to be changed. Concepts like MVS item, Bonus item, Active Sub, Corp view, Sub Distr, Purch Sub had to be incorporated in the process. Forecasted orders that were earlier provided at the primary level had to be provided at the sub level to business users and vendors. CFP application had to be provided with the flexibility to view totals by Control WIC for all DCs or totals by WIC only for the DCs that WIC is supplied to. Users need to have multiple views to allow different roll-ups depending on how they intend to use CFP to work alerts, collaborate with a vendor or export data for analysis. VIF and EDI supply processes had to be changed to provide them the view of forecasted data and Item/Distr information at different levels. PMM data had to be interpreted and processed with the changing levels of Distr information.

Project: Item Sub-owner for RDF Workbooks

RDF workbooks are grid/graph views for day to day approvals and adjustment by RDF Forecasters and RBs. Workbooks are created by IF weekend batch and can be also created manually.

There are mainly two issues with current design:

• When a single RB or forecaster is assigned a huge number of opstudy and items, workbooks take too long to be built.

• New opstudy does not automatically come in WB. Since WB are created by a reference set of opstudy, which is static, new opstudy gets missed coming into WB if it is not in the reference file.

To resolve the issue, the new design will update the RDF product hierarchy to split the workbook in smaller sizes. This split will be based upon user provided data where one RB/FCT will be split in multiple for different sets of opstudy. Unlike static reference files, this process will be dynamic and include new opstudy every week. Also WB built time will be reduced due to the split of one big WB into many.

Project: IF PMM process revamp

Promotional Merchandise Management is a Walgreen custom built tool to forecast and manage promotional events. When there is a Promotional Event at the store, the appropriate PMM forecasts are selected so that an Ad Bulletin Projected Store Order can be generated in a future step. Only weeks with promotion events should have an Ad Bulletin Projected Store Order attached. Every week IF process gets feed from the PMM system regarding the promotions going on for different Walgreen items at different US locations. IF process then converts the feed to promotion forecasts for the items and sends it to PSO in order to generate orders.The IF PMM process needs to be revamped in order to improve the accuracy of PMM forecast that it generates for PSO. The sub processes like Ad Overlapping and Distr Overlapping need to be restructured. The concept of rolling ahead the PMM forecast for an Item on a particular Ad at a particular location, in order to replenish the store before the promotion starts needs to be revised.

Project: Scan week to Ad week conversion

The DC Forecasting week is Sun-Sat to allow replenishment buyers to have all information available to them on a Monday morning. Hence PMM week must align to this week.Two Wed-Tue PMM forecasts are generated for one Sun-Sat promotion week. These forecasts need to be summed to get total promo demand so that inventory can be ordered and front loaded before the promotion.

Action Items:

a)If a store adjusted PMM forecast exists, replace the original PMM forecast for week X and week X+1 with the store adjusted PMM forecasts(these incorporate store manager changes to suggested ad bulletin quantities.) Otherwise, use the original PMM forecasts for week X and

week X+1.

b)Add the non-zero PMM forecast for week X to the non-zero PMM forecast for week X+1 to get the total promo sales forecast for the event

this week.
