The solution design process begins once the analysis phase has been completed. By now, the project plan is ready, the requirements document has been signed off, the Conference Room Pilot (CRP) has been completed, and the fit-gap exercise has been completed and documented as part of the analysis phase. In the fit-gap exercise, if the team has decided on using some ISV solution to fill the gaps, then you may need to evaluate the best ISV solution. For any other gaps, the implementation team needs to document the overall solution and produce the functional and technical design documents to address the gaps through customization and extension. However, before starting on writing design documents, a functional and technical consultant also needs to know the common features that can be used to fill the gaps or complement the solution design they are proposing. 

In this chapter, we will cover the following topics:

• Finding the right app for your business needs
• Common features
• The functional design document 
• The solution design document 
• The technical design document
