Understand the technology estateyou already own.
Most transformation programmes begin with a discovery phase that produces a document. The document is accurate on the day it is signed off and decays from there. The estate keeps changing; the understanding does not.
/ the situation
The estate keeps changing. The understanding does not.
Most transformation programmes begin with a discovery phase that produces a document. The document is accurate on the day it is signed off and decays from there.
/ the questions
Six questions the register cannot answer.
What systems hold customer data?
Including the ones procured by a department and never added to the register.
Where is duplication?
Two systems performing the same function for different teams, both paid for.
What breaks if we retire this system?
Named systems, named fields, named processes, named owners.
What depends on this API?
Every consumer, every version, every automation that touches it.
Where could we consolidate?
Overlapping capability, ranked by what it would cost to remove.
What must be migrated first?
Sequence derived from dependency, not from programme convenience.
/ why documents decay
A discovery phase produces a snapshot of a moving thing.
It is accurate on the day it is signed off. Every vendor release, every departmental purchase and every retirement moves the estate out from under it, and nothing re-runs the discovery until the next programme pays for it again.
/ why the answers hold
Rebuilt continuously from the systems themselves.
The understanding is derived rather than drawn. When a vendor changes an API, the estate model changes with it. There is no document to go stale.
/ what it is worth
The discovery phase stops being a cost you pay per programme.
The same understanding serves integration, automation, governance and migration, and it is current when the next programme starts rather than needing to be established again. Environments describes how deployment and operational responsibility change as that scale grows.
Start with the part of the estate nobody wants to touch.
The system everyone routes around is usually the one holding the relationships that matter.
