Want to find out if a Design Sprint is the right first step for your project? Schedule an introductory meeting and let's look together at your challenge and how we go from insight to solution.

The Challenge
The maintenance calculation process was fragmented across individual Excel files, which made it error-prone, hard to oversee and difficult to scale.
Before Product League built a new platform for this, both parties wanted to be sure the direction was right. The solution had to match how specialists really work. The organisation's key concerns also had to be taken seriously upfront.


Our Approach
Product League chose a phased approach:
- First a Design Sprint to gain a shared grip on the current situation and the key pain points, then a Proof of Concept to make the chosen direction concrete
- Full platform development followed. This delivers a validated first-time-right process, instead of still having to search during development for what is really needed.

Deep dive
The sprint consisted of a number of consecutive steps, spread across half-day sessions.
From deep dive to wireframe
- Deep dive – broadly gathering what is going on: goals, context and the key pain points in business, IT and operations.
- Walking through the current process – looking in detail at how processes and systems currently function, including the exceptions that cause most problems in a spreadsheet-based approach.
- To wireframes – translating the gathered insights into concrete sketches of a possible solution.
- Validating with end users – the wireframes were briefly presented to end users, so the direction was tested against reality early on.

The Result
By first taking the time for a deep dive and validation, a shared and tested picture of the challenge emerged before the build began. This delivered not only a validated direction, but also buy-in from the decision maker and end users to actually follow that direction. From the wireframes, the project moved straight into a Proof of Concept, as the first tangible step towards the platform that grew out of it.
