W8_AFS_ Managing Small Project: Work Breakdown Structure Selection


Problem Recognition, Definition, and Evaluation

The new project has been established with name Water Pre Treatment Package Project. The Project objectives are:

  1. To ensure there is no solid particles carry over from water well to WTP
  2. To increase potable water production capacity
  3. To reduce time for backwash activity
  4. To Prevent RO membranes damage due to contamination in its feed water

During FEL-0, Operation people defined that to achieve all of project objective above, we shall install pre-treatment unit at Upstream of WTP. This week blog, we will try to select WBS with using multi attributes decision making technique

Development of The Feasible Alternatives

There are 3 WBS alternatives to compare

  1. Homegrown WBS (explained on my W5 blog)
  2. Omniclass 3D WBS (explained on my W6 blog)
  3. Norsok 3D WBS (explained on my W7 blog)

Development of The Outcomes For Each Alternative

Selecting the optimum WBS which is more fitted to this project

Selection of Criteria

There 4 selections criteria that will be used as parameters

  1. Level of Details, this will explain how detail each alternative structures their WBS for design process.
  2. Number of design activity phase, is the number of engineering phase from the project scope development to the final design.
  3. Work flow of activities, is how the activities work together from the project scope development to the final design.
  4. Complexity of the WBS

Analysis and Comparison of The Alternatives

We will using one of noncompensatory model as our tools which called Lexicography. Lexicography is particularly used to judge a single attribute is more important than all other attributes.

Selection of The Preferred Alternatives

Summary Information for Selecting WBS to this project


Table 1. Summary Information

Ordinal ranking is to make paired comparisons between each possible attribute combination


Table 2. Ordinal Ranking of Attributes

Following table is illustrates the application of lexicography to the ordinal ranking developed in table 2.


Table 3. Application of Lexicography

Performance Monitoring and Post-Evaluation of Results

Based on exercised above, the preferred alternatives is Omniclass 3D WBS. The Omniclass 3D WBS is giving us level of details is better than the Norsok 3D WBS which is the second option. The level of details is the most important attributes due to by knowing the detail of the project scope, we can eliminate all the possibility of increase the cost or delaying project due to additional activities (growing scope) that is not defined on the planning phase.

  1. Awesome case study and very well done analysis….. Big question is whether you can convince your management to switch from a home-grown to a standardized WBS?

    Keep us updated on your progress!!! IF they do agree to adopt Omniclass, it will save them many times over the cost of your training in this course!!!!

    THIS is the kind of “Return on Training Investment” (RoTI) that I would hope to see from everyone.
