Application portfolio assessment
Each system rated for business fit and technical condition, with the resulting course: tolerate, invest, migrate or eliminate.
The deliverable
What it is
The TIME model, associated with Gartner’s application portfolio work, sorts systems on two axes into four courses of action. Its usefulness is that it forces a verdict for every system, including the unglamorous ones that would otherwise continue by default.
The assessment rates the entries of the system landscape and does not keep a list of its own. The replacement dates and costs of held assets are recorded under Business Assets as lifecycle; this assessment decides what should happen to each system architecturally.
