The big difference from the monolith, though, is that this is now a standalone service deployed as a separate “application” (service) in our cloud infrastructure. Functional Testing Functional testing was the most straightforward of them all: a set of tests alongside each path exercised it against the old and new endpoints.

It’s a known fact that if we setup all the infrastructure needed for cross-browser testing, we would need to invest in the maintenance and up-gradation of both old and new browsers as well. One of the biggest concerns with a traditional setup is that we still pay for its maintenance and infrastructure even when they’re not in use.

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. STPA is based on a functional control diagram of the system, and the safety constraints and requirements for each component in the design.

Employees will see replatforming as an exercise in re-creating software. Not only is this not value-generative, it adds a layer of decision making intermediation and creates ambiguity in responsibilities for requirements, analysis, design, and prioritization. We'll build the platform first, then change the organization once it's live.

In some cases, if only a very few, these assets continue to be used because they still work very well, were thoughtfully designed, and have been well cared for over the years. The exercise of assessing, modeling and dispositioning the landscape does offer valuable new ways of looking at legacy assets.
