Activity A4.16

Plan construction and implementation stages

¤ Prepare implementation plan

Prepare the implementation plan which should include a schedule covering the construction and implementation stages.

» Creates deliverable D4.3.5 Implementation Plan.

¤ Review costs and benefits

Prepare a cost-benefit summary report. The remaining development costs can be accurately estimated from the implementation plan, so a new figure for the total expected development costs can now be produced.

The production costs were estimated at the end of BSD. More reliable production costs can now be estimated, based on the performance assessment summary prepared in the Assess Performance task of TD.

The benefits of installing the implementation area's system were previously quantified in BSD. These benefits should be reviewed, but they should not have changed unless the scope of the system has changed significantly.

¤ Gain management approval

Senior managers review the implementation plan and the cost/benefit summary. As a result, they may give the go-ahead, cancel the project, postpone the project, or seek changes to the project scope or plans.

If senior managers seek changes to the project scope or plans, they should state:

* What they do not approve of in the plan

* Areas they recommend for modification

* The nature of the modification required (e.g., postponement of some less-essential procedure, faster transition to some procedures, less-sophisticated terminals)

* Whether several alternative plans are to be prepared

* Required return on investment

ð Updates deliverable D4.3.5 Implementation Plan.

¤ Iterate

This subtask is performed only if requested by senior management in the previous subtask, Gain Management Approval.

The project team investigates the recommendations made by senior management and prepares:

* Proposed modifications to the current design, by repeating earlier BSD and TD tasks

* One or more new implementation plans

If the new plan is approved by management, the design is formally changed in the information library.

» Creates deliverable D4.28 Construction Plan.

ð Updates deliverable D4.3.5 Implementation Plan.
