I found a great Gartner article which details a documentation checklist needed for a successful project. This article is specific to ERP projects, but can be leveraged for many other types of projects. The checklist includes the following items:
- Business strategy
- IT strategy
- Application strategy
- Business case
- Selection artifacts
- Project charter
- Project plan
- Board approval documents
- Project status reports
- As-Is and To-Be process documentation
- Gap analysis and gap closure documents
- Customization documentation, including modifications, reports and interfaces
- RICEFW objects and documentation, including objects' owners and business cases for justification of the objects
- All licenses for the software and hardware covered by the project, including any license restrictions
- All maintenance agreements with software and hardware vendors or third parties, including SLAs
- Organizational change management plan, including status
- Risk management plan, including status
- Benefits realization plan, including assigned metrics
- Blueprint/configuration documentation
- Milestone sign-off/acceptance documents
- Testing strategy, including test data, plans, scripts and tools for future changes
- Testing documentation, including unit, integration, capacity/volume and user acceptance testing (UAT)
- Training documentation, including training needs, training plan, training evaluation and ongoing training
- Data conversion documentation
- Support model
- Support roles and responsibilities (if not included in the support model)
- User procedures
- System operation procedures
- Change control/release management strategy and schedule
- Open issues register
- Escalation process (Tier 1, Tier 2, Tier 3 rules)
- Governance model
- Post-implementation review schedule
This full list provides a great understanding of the types of items required from a documentation perspective and is a fairly comprehensive list.
