DSM helps Dunelm realign SAP landscape

Dunelm realigns its SAP non-production system landscape with Data Sync Manager (DSM) and moves to AWS

Data Sync Manager is very good at taking selective pieces of data that we need, and slicing that into different sizes. So for each environment, you wouldn’t necessarily take the same amount of data, because you don’t need as much data in a sandbox system as in a test system. So DSM is good at slicing and dicing the data as you need it, to reduce size.

Dunelm: the UK's largest homewares retailer

Dunelm is the UK’s largest homewares retailer with a wide range of products for every room in the home. The Dunelm story started 40 years ago, when founder Bill Adderley decided to take on a stall with his wife at the Leicester Market. Since then, the company has grown to what is today a multi-channel retailer with 169 superstores, three high-street stores and a web-store, featuring extended ranges and delivery convenience.


About Dunelm

Dunelm's SAP landscape challenges

As part of a newly deployed SAP Hybrid Cloud landscape, a key requirement for Dunelm was to realign and rationalise its SAP non-production systems. The current systems were not being used for their intended purpose, and the lack of a formal data refresh strategy exacerbated the problem of out-of-date data. Ageing data in test environments had a negative impact on the quality of testing, ultimately increased the risk of issues in the productive environment.

The high demand of everyday Basis tasks consumed all resources and made refresh activities even more challenging to prioritise internally. Consequently, over time the rapidly ageing data in test environments was impacting the quality of all BAU activities and project testing, increasing project timelines and increasing the risk of major incidents in the productive environment. In addition, Dunelm wanted to move their Development, Quality Assurance and Sandbox SAP systems to Amazon Web Services (AWS).

Dunelm runs multiple projects in parallel. The demand on the IT infrastructure was high with the need for multiple systems for all the projects, and no opportunity for downtime to provide traditional SAP system copies or refreshes. Dunelm’s landscape didn’t support an agile development approach; inadequate testing at an early stage resulted in disruptive changes in the production system.

The scope of the realignment project

The scope of the realignment project included SAP ECC (Enterprise Central Component), SAP EWM (Extended Warehouse Management), SAP PI (Process Integration) and SAP BW (Business Warehouse) systems.

The EPI-USE Labs team held a workshop with the Dunelm team to define the project scope, and suggested the process for the landscape realignment. Once agreed, this formed the project plan for creating the new landscape. The new systems would be built on new infrastructure in the AWS public cloud environment.

The project was mapped to three simple steps: Build, Refresh, Transform.

Scope: Build, Refresh, Transform

One of the key elements for us was the flexibility that the EPI-USE Labs team provided, both with landscape alignment and on a project management level. Dunelm did not have the resources to do that. We needed a partner that could come in with a technical mindset as well as a project management mindset.

Dunelm benefits from Data Sync Manager

The benefits of the project are that Dunelm now has a fully refreshed 5-tier landscape that has a Sandbox environment as well as a Pre-production. All the systems have been configured and there is data alignment across the landscape. Dunelm has implemented Governance around development and change processes, a transport management tool and a refresh strategy while migrating all the systems to the cloud. The ultimate benefit is that the Dunelm team now has the setup to perform regression, integration and performance testing before changes go into production, and this gives them confidence in the testing outcomes.

The simplicity of Data Sync Manager for rapid landscape transformation was a key factor that ensured a successful project. This, combined with the expertise from the EPI-USE Labs team across the fields of Project Management, Basis, and GDPR and Data Security, gave Dunelm the broad spectrum of skills that they did not have internally. Steve Ross notes, “One of the key elements for us was the flexibility that the EPI-USE Labs team provided, both technically and on a project management level.”

The EPI-USE Labs team showed that they had the ability to become part of the Dunelm team; they had an excellent depth of knowledge, and the ability to engage with multiple internal teams with a “can-do” attitude. The combination of using software with the right team guaranteed that Dunelm has a landscape that can support their business into the future.

The EPI-USE Labs team was very good at communicating the need, requirements and benefits of the projects and to get buy-in from the project teams so that everyone knew what we needed to do.
