Background

The client, a renowned premium apparel company, places significant emphasis on merchandise planning and allocation within its business operations. This strategic approach ensures that stores are well-equipped with vital information such as inventory management, order planning, and store layout optimization. Initially relying on Anaplan, the client encountered challenges as data volume increased, leading to the development of TIGER (Transfer Engine) utilizing PySpark. This solution aimed to enhance customization and flexibility within the planning process, reflecting the client's commitment to operational efficiency and customer service.

Pain Point

Despite meticulous efforts to mirror Anaplan's codebase, the client's internal Transfer Engine faced a significant setback in execution time. While Anaplan completed processes within a swift 60 minutes, the Transfer Engine lagged far behind, requiring a cumbersome 240 minutes for execution.

This notable disparity posed a considerable challenge for the client, impacting critical planning processes and store operations. The extended runtime not only hindered operational efficiency but also led to delayed decision-making, directly affecting revenue potential and customer experience.

As a result, the client recognized an urgent need to address the inefficiencies plaguing their in-house Transfer Engine, seeking a customizable and scalable solution to align with their operational objectives.

Key Objectives

1. Improve Transfer Engine's performance, scalability, and aim for a daily runtime closer to one hour.
2. Extend planning capacity to accommodate long-term goals, targeting up to 500 days of planning.
3. Enable the client to seamlessly generate automatic purchase orders based on available inventory, aligning with the planned strategy.

Solution

To address the performance issues of the Transfer Engine, a collaborative effort was orchestrated involving both the client's internal team and Altimetrik. The approach involved solving the problem for an impactful category – Women’s Pants!

The process began with an in-depth analysis of the Transfer Engine's codebase, where various inefficiencies were identified.
