Making a critical integration easier to support and extend
As a critical integration became harder to change and support, I made the case to C-level executives for delaying new features and investing in a more robust foundation. With their backing, I supported my team through the rebuild, accepting a short-term delay so the integration could better support the business over time.
When progress became harder
I was the IT owner supporting a regional retailer’s demand-planning and replenishment transformation. My team developed integrations connecting the planning platform with the ERP and warehouse systems.
As the integration grew, issues accumulated and became harder to diagnose and resolve. Changes required more investigation, and the connections between different flows made it difficult to assess their effects. We needed to reconsider the design before continuing to add to it.
Making the case
I recommended pausing new functionality so the team could refactor the integration. That was a difficult trade-off: business users were waiting for capabilities they could use, and we were asking for more development effort before delivering them.
My main contribution was making that case to C-level executives. I explained how the growing complexity was affecting delivery and support, why adding more functionality would make the underlying problems harder to address, and what we expected to gain from a more robust foundation. We discussed the additional investment and the cost of delaying features, and secured support for the work.
With that agreement in place, I backed the team through the rebuild and kept business leaders informed about what would wait and why. The decision required taking a longer view of the platform while acknowledging the immediate needs of its users.
What we changed
The team developed a more modular design, separating different flows into smaller components and improving visibility into processing and exceptions. I supported their technical decisions and helped them carry the work through, with the executive backing we had secured.
It became easier to understand what had been processed, locate problems and work on one part without having to untangle the entire interface. That gave us a more manageable foundation for continued development.
