4.1 Traditional Calculation
A traditionally developed project plan typically consists of:
- 250 work tasks
- 50 specific deliverables
- A PERT chart
- Assignment of staff
- Development of a project management proposal
The amount of time for such a project is commonly:
- Work tasks of 3 minutes each or 12 hours
- Deliverable specification at 1 hour each or 50 hours
- PERT chart at 2 minutes per task or 10 hours
- Assignment of staff at 3 minutes per task or 12 hours
- Development of an overall project management proposal, 8 hours
The total time is therefore 92 hours or 8 calendar days.
4.2 Changed Approach Calculation
- Initialize Project Table, 2 minutes
- Select Project Templates, 5 minutes
- Generate Work Plan that includes deliverables and tasks, 20 minutes
- Assign Work Environment Factors to Deliverables, 1 minute each
- Assignment of staff to deliverables, 2 minutes each or 2.5 hours
- Generate complete set of required resources, 10 minutes.
- Export Project Data for Project Graphics, 10 minutes.
- Import and Generate Project Graphics, 20 minutes.
- Development of an overall project management proposal, 2 hours.
The total time is therefore, 5 hours or one staff day.
4.3 ROI Summary
Comparing the two approaches, the traditional approach, even if a correct one, takes about 92 hours or 8 days. In contrast, using the Whitemarsh Project Management system takes about 5 total hours. That's a 16:1 ROI. More that 10:1 means that this approach is a Project Management Silver Bullet.
4.4 The "Real" ROI
The real ROI is almost incalculable because with the Whitemarsh Project Management approach:
- Every WBS is drawn from a standardized collection of that makes comparisons quick and easy.
- The assignment of and assessment of assigned persons is both easy and comparable as deliverable-accomplishment results are entered by each assigned person on a no less than weekly basis.
- Every deliverable specification is standardized, and the actual deliverables accomplished are able to be retrieved and reviewed during the project's actual execution.
- The effect of assigned work environments can be determined, and if possible changed along with the ability to re-generate the remaining project deliverables estimates.
- Quick, easy, and effective assessment of various project performance across the enterprise by mission, organization, business function, and by type of deliverable.
- Quick and easy prototyping of project plans through changes in person skill and performance levels and changes in work environment factors.
- Generation of current and predicted earned value reports.
