discover and define
The second stage serves to
specify the solution
with the objective of confirming value, establish more accurate costs, and identify the potential risks.
The value, cost, and risk (VCR) is compared to the expected return on investment. If the solution is viable -- ROI exceeds VCR -- the documentation is forwarded to the next two stages.
If the solution is not viable, the specification can be modified until an acceptable ROI is reached, or we may return to the possible solutions identified during stage one and repeat this second stage with a different set of assumptions.
deploy and release
The final stage launches or releases the specified solution into common use. This includes
the "early life" support of the solution as well as promoting the solution to customers
Live deployment also means maintaining and supporting the solution into the future, and collecting issues and ideas for future improvement of the product.
