||Date: 2008/02/25 13:41:28
The list below describes the steps necessary to perform in order to create a DEX.
- Identify the business need to be supported by a DEX.
- Send a request to the organisation or person who is responsible for the management
of the DEXs. The request should contain,
- The business needs, which should be the basis for the scope statement.
- Life cycle stage.
- Request responsible.
- Investigate whether the business need is covered, or partly covered, of an existing
DEX. Compare business needs with business needs already covered by DEXs. All needs
must be supported by capabilities. Investigate if existing capabilities are relevant
for the business needs.
- If a new DEX has to be defined, a new unique number is allocated to the DEX in
addition to a short name and a long name. If the business need is partly covered by
an existing DEX it has to be considered if a new DEX shall be defined.
- Create a new DEX in DEXLIB.
- Run '\dexlib\utils\dex\mk_DEX.wsf' to create DEX XML outline.
- Update '\dexlib\dex_index.xml' with the DEX short name.
- Perform the capability dependence check in DEXlib.
- Write the introduction statement.
- Write the scope statements.
- Describe the business process. All PLCS DEXs should be related to the AAM model.
- Establish a DEX longform.
- Establish test plans.
- Perform testing. Reference should be made to separate document for testing of DEXs
- Quality assurance, see separate check list...
