Waterfall methodology for Microsoft Dynamics 365 Finance and Operations one version

waterfall implementation has following phases :

• Diagnostic: This is primarily presales phase or requirement gathering phase.
• Analysis: This is the phase where an advisor/partner understands requirements and maps them with the solution. During this phase, the extent of solution fitment becomes known and the decision to customize, buy, or build the solution verticals are decided upon.
• Design: In this phase, solution blueprint needs to be prepared, which in turn needs to be supported with other designs, such as functional, technical, data migration, security, and so on. This is done for both fitment as well as solution gap areas.
• Development: In this phase, all gaps for which design documents are prepared in the earlier phase are undertaken for development and unit testing. Some implementations perform functional testing as part of this phase or in the subsequent phase.
• Deployment: This is solution validation phase, where solution is tested to fit the business requirements of the initiative. Preparation for go-live also happens in this phase and so do activities and deliverables related to data migration, security, training, and so on. 
• Operation: This is the phase after go-live, often known as support/sustenance.
