The system is being complete replaced . It is not uncommon to see homegrown systems for human resource functions being replaced by COTS systems such as SAP or Oracle Financials.

  • The system no longer needed to support the current business model . A organization may explore a new business area by developing new systems only to discover that it is not cost effective.
  • The system is redundant . Organizations that grow by mergers and/or acquisitions often end up with redundant systems as they consolidate their operations.
  • The system has become obsolete .
  • In most cases, the retirement of older releases is a handled during the deployment of a newer version of the system and is a relatively simple exercise. Typically, the deployment of the new release includes steps to remove the previous release. There are times, however, when you do not retire a release simply because you deploy a newer version. This may happen if you can not require users to migrate to the new release or if you must maintain an older system for backward compatibility.

For example, rather than one engineer or team creating one cooling system design, several alternatives may be explored at Toyota in parallel by different teams—and so too for other components. These sets of alternatives are explored and combined, and gradually filtered in cycles, converging on a solution from what was at first a large set of alternatives, then a smaller set, and so on. They outlearn the competition by increasing alternatives and combinations .
