Scope Management

Scope Management means:

  1. Not letting others randomly expand the scope of the project without a structured change control system

  2. Constantly verifying the completion of all authorized work

  3. Ensure all changes are within the project charter

  4. Defining and controlling what is and is not included in the project

  5. Not allowing extra work or gold plating

You can read more about it on Wikipedia.  (Yes, I contribute to this definition)

Functional Management

Functional management is the most common type of organizational management. The organization is grouped by areas of specialty within different functional areas (e.g., finance, marketing, and engineering). Some refer to a functional area as a "silo." Communications generally occurs within a single department. If information or project work is needed from another department, a request is transmitted up to the department head, who communicates the request to the other department head. Otherwise, communication stays within the department. Team members complete project work in addition to normal department work. By the way, when you go to Wikipedia and read about Functional Management, know that I was the creator of the page.

Gold Plating

Triple Constraint

I once had a customer became highly incensed when told the deliverables he wanted were not going to be completed on time, due to a lack of resources.  He said he didn't understand why his highest priorities didn't get completed but extra features not asked for were.  When told additional features had recently become priorities he strongly disagreed.  His response was the person requesting or making the changes thought the changes were important but they were NOT.  If the changes were important, they would have been requested directly by the President of the company. (It sounds dramatic but it was true) Though there were certainly issues, at the time, as to who had authority to authorize a change, what happened was an example of gold plating.  Gold plating refers to providing the customer more then they ask for. (e.g expanded scope, functionality, higher quality)  Though this practice is based on what someone thinks the customer would like, it doesn't necessarily add any real value.  Both risk and cost will increase on the project because the requirements must still be met in the allotted time and budget.  As tempting as it might be, it is strongly recommended not to gold plate.  Try to make your customer happy by keeping your project within scope, on time, and on budget.

If your customer (or person authorized to approve a change) does indicate the change will add value, inform them of the impacts to the schedule and budget (and potentially quality and risk) and get their formal agreement to do the work.  Though it's easy to say you should not agree to make the change, the reality is you need to make the customer happy and they will make the final call.  Negotiate with them, to ensure the requested change will have a minimal impact to the current scope being completed.  In a perfect project management world, free of zombies and runaway stakeholders, there would be a separate funding vehicle and it would not impact the baseline.

PERT Formula

PERT - Program Evaluation and Review Technique.If you’re going to take the PMP exam, you MUST remember this formula.  I’ve used it countless times in the real world and it works with surprising accuracy.

Formula: (P+4M+O)/6

Optimistic time (O): the minimum possible time required to accomplish a task, assuming everything proceeds better than is normally expected. Pessimistic time (P): the maximum possible time required to accomplish a task, assuming everything goes wrong (excluding major catastrophes). Most likely time (M): the best estimate of the time required to accomplish a task, assuming everything proceeds as normal.

How does it work?

Obtain three time estimates (optimistic, pessimistic, and most likely) for every activity along the critical path.  Plug your numbers into the formula and then sum the totals.  Though people will challenge you, you WILL have a more accurate critical path estimate.

I will speak to “Standard Deviation of an Activity” and “Variance of an Activity” at a later time.   They both leverage the same values but in different formulas.

Finding the critical path

PERT Critical Path Method includes determining the longest path in a network diagram and the earliest and latest an activity can start and the earliest and the latest that activity can be completed.  Here are a few basic things you need to think about.

  • It is the longest duration path through a network diagram and determines the shortest time to complete the project
  • It helps prove how long the project will take
  • It helps the project manager determine where best to focus his or her efforts
  • It provides a method to compress the schedule during the project planning phase and whenever there are changes
  • It provides a method to determine which activities have float and can be delayed without delaying the overall project.

The easiest way to find the critical path is to identify all paths through the network and add the activity durations along each path.  The path with the longest duration is the critical path.
