Real World Example

Motto: Better, faster, cheaper
Three year development cycle with a $150 million cost cap, managed by Jet Propulsion Laboratory.
Critical 30 day launch window occurs only every 26 months.

Real World Example
te: Pinnacol Assurance – A Denver-based Medical Insurance Provider (page 122)
Current system was a disaster with huge backlogs and daily overpayments of more than $5,000.
A new project was started with a six month time frame and a development staff of two dozen.
No project management principles were applied and the project spiraled out of control. Twelve months later nothing had been delivered and jobs were on the line.
A project re-start was initiated with clear objectives and controls. This time the deadline never budged!

Project Control Process
The key to effective project control is to measure actual progress pare it to planned progress on a timely and regular basis and to take necessary corrective action immediately.
Establish a regular reporting period.
During each reporting period, collect:
data on actual performance
information on any changes to project scope, schedule and budget.
If changes are incorporated, a new plan must be established.

Effects of Actual Schedule Performance
Actual finish times (AFT) pleted activities will determine the earliest start and earliest finish times for the remaining activities.

Incorporating Project Changes into the Schedule
Changes might be initiated by the customer or the project
