01 · Starting point
Situation
Applications had to be made compatible across different systems and then rolled out in a controlled way as a software or system upgrade.
Constraints
- Changes within an already established IT environment
- Short, clearly scoped engagement
- Internal system and operating details remain confidential
02 · Responsibility
My scope of responsibility
I designed and documented the initiative, analysed application compatibility and planned and monitored the rollout phase.
- I analysed application compatibility issues on different target systems.
- I supported the implementation and monitored the rollout process.
03 · Technical work
Documented scope of work
Key decisions
Establish compatibility analysis as a mandatory gate before the rollout. Problems should surface before broad distribution instead of escalating in the production rollout wave.
- I created a rollout strategy for software and system upgrades.
