Which situation do you recognise?
Choose a scenario. Explore the problem and the possible paths worth evaluating.
01 Where do you start from?
Code and databases are accessible in all three scenarios.
We know how it works, but keeping it running costs too much.
People and documents are available. The work stays slow, expensive, or weighed down by accumulated interventions.
Choose this scenario →Everything looked clear. Then we tried to change it.
Documents and estimates seemed enough, but projects stalled or created new problems.
Choose this scenario →We have code and data. Nobody can explain the rules anymore.
The people who knew the system are gone, and available sources say little about how it is really used.
Selected ✓02 What is the specific problem?
What happens when a rule changes?
How a function behaves is unclear, and there may be dependencies nobody remembers.
Choose this problem →What happens to our historical archives?
The data is available, but its meaning and relationships accumulated over years are not documented enough.
