Planning

The service include the robust appraisal of different delivery options for your project. Depending on the case stage, the team can facilitate workshops to develop high level implementation approaches, can cost more detailed delivery options or can develop more complex cost models to consider different implementation scenarios for an already selected option. For the selected option, the team can facilitate planning and scheduling of delivery with the project team or delivery partner, including the prioritisation of a delivery backlog, the breakdown of work into a defined methodology and the forecasting of delivery cadence accounting for risk. With either an outline or more detailed implementation plan, the team can develop benefits models to forecast the realisation of benefit in line with delivery milestones, including the consideration of different scenarios and multi-point estimates of modelled parameters where required. The team can consider the role of optimism bias and risk in an implementation plan, modelling risk scenarios with associated impacts to cost, schedule and quality of the delivered service. The team can calculate optimism bias to cover residual uncertainty and to more accurately forecast the eventual whole life cost of the implementation. The team can also model ongoing run costs post-implementation.

Setup and migration

The team can support the appraisal of the best option and approach for cloud migration and can appraise the relative costs and benefits of different services. The team can facilitate market test exercises through to full procurements to appraise detailed responses from competing suppliers of target services. The team can provide a comparative cost benefit analysis of on-premise and cloud based services to determine the net benefit of planned cloud migrations.
