TIME Model

Tolerate: An application with high technical quality, but sub-optimal functional business value. The applications should be redesigned for better business alignment.

Invest: An application with high technical and business value. There is an attributable and recognizable value - and high and/or critical usage. The application is worth continued investment to get even better returns or reduce more costs.

Migrate: An application has high business value, but a poor technical fit. Discard the application but migrate its data and users to a new application or to a better-fit existing application.

Eliminate: Eliminate useless applications with low business value and a poor technical fit (possible reasons; no business value, not used, low utility, based on obsolete software)
