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 release is no longer to be supported . Sometimes organizations will have several releases in production at the same time, and over time older releases are dropped.
  • 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  • In most cases, the retirement of older releases is a handled during the deployment of a newer version of the system and is a relatively simple exercise.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.

    Progress in manufacturing is measured by the production of high quality goods. The unit of progress for Lean Startups is validated learning-a rigorous method for demonstrating progress when one is embedded in the soil of extreme uncertainty. Once entrepreneurs embrace validated learning, the development process can shrink substantially. When you focus on figuring the right thing to build-the thing customers want and will pay for-you need not spend months waiting for a product beta launch to change the company's direction. Instead, entrepreneurs can adapt their plans incrementally, inch by inch, minute by minute.

    Waste reduction directly correlates with reduced energy consumption and carbon generation. Indeed, IBM asserts that IT and energy costs can account for up to 60% of an organization's capital expenditures and 75% of operational expenditures. [26] In this way, identification and streamlining of IT value streams supports the measurement and improvement of carbon footprints and other green metrics. [27] For instance, implementation of Lean IT initiatives is likely to save energy through adoption of virtualization technology and data center consolidation. [28] [29]

    Component teams are faster at developing customer features that primarily involve their single-speciality component—if such single-component customer features can be found (not always true). For that reason, when people are sitting in a room deciding what to do next, features are often selected according to what available component teams can do best or quickest. This tends to maximize the amount of code generated, but does not maximize the value delivered. [6] Therefore, component teams are optimized for quickly developing features (or parts of features) that are easiest to do, rather than of highest value . We once saw a component team assigned to code their small part of a low-priority customer feature that was not due for more than 18 months in the future, simply because it was easier to plan that way.
