W2_Muslem_Introducing WBS and WBS Coding to Project Development.
Opportunity
Definition:
Project Development Department (PDD) in OPWP is responsible
for developing project requirements of any new power and water capacities, and conducting
a fair and transparent competition process to procure a qualified developer for
the supply of such capacities. PDD has been following a standard procurement process
for both power and water projects until recently when new-in-nature
projects are handed over to the department. The objective of this report is to identify
the best approach to create a standard WBS for any new procurement, encouraging
the implementation of WBS coding and potentially WBS Dictionary in the department.Figure 1: Sample of PDD's Current Practice in Scope Definition |
Feasible Approaches to Develop WBS:
There are a number of approaches to develop the WBS for any new procurement; include analogy approach, top-down approach, and bottom-up approach [1,2]. Analogy approach is the use of the WBS of a similar procurement process that have been done in the past. Top-down approach is the process of decomposing bigger tasks into smaller and manageable components until deliverables are detailed enough. Bottom-up approach requires a brainstorming activity to list down all the tasks and deliverables needed for the successful procurement, which then grouped into phases.
Outcomes of Each
Approach:
Adopting an analogy approach would make it easier and
quicker for the team to use already designed templates for new procurements as
a starting point. Top-down approach uses past experience to initially list down
all big deliverables, then develop the detailed WBS. Bottom-up approach, on the
other hand, can be potentially more efficient to identify all deliverables because of high team input. This approach, however,
is a very time consuming process [3].
Selection of
Criteria:
Ease of implementation, and completeness or quality of the delivered
WBS are two important criteria for selecting a preferred approach.
Analysis and Comparison
of Approaches:
Analogy approach is easy and effective when WBS for similar procurement
has been created previously, which is not in our case currently. Top-down
approach is a more plausible option as the key deliverables are known due to PDD’s
long years of experience in the procurement of power and water projects. However,
and due to the new nature of current projects, there is a need to identify some
new or additional deliverables or tasks. Bottom-up approach would be helpful in
this case through brainstorming sessions led by the PDD team. This would avoid the
late identification of critical tasks, which might cause unnecessary delays or unplanned
costs.
Selection of Preferred
Approach:
The preferred approach is recommended to be a combination of
top-down approach, through using scope of similar previous procurements, and bottom
up approach to identify any specific new requirements or tasks for the specific
nature of the project.

Post Implementation;
The initially developed WBS might not be complete. Therefore,
it is recommended to keep track of unplanned deliverables or tasks, and log
them as lessons learnt to improve the WBS for the next procurement cycle. It is
also recommended to follow an analogy approach for the next procurement process
using the already created WBS and coding structure as a base.

Very well done analysis Muslem but your posting raises a couple of very serious questions and they are 1) Why are you using a FLAT FILE (single dimension) WBS when clearly the best practices are showing that a RELATIONAL or OBJECT oriented, Multi-Dimensional WBS structures are the way to go and 2) Why are you "reinventing the wheel" by creating your own "ad hoc" or "custom built" WBS structures when there are already in existence STANDARDIZED WBS such as Omniclass?
ReplyDeleteI would hope that you dig deeper into this subject and start to think critically about the pros and cons of creating "ad hoc" single dimensional systems over the advantages of adopting multi-dimensional WBS structures that have been STANDARDIZED.
Well worth another 2 or maybe even three blogs to explore this subject in more detail.... ?
