W10_TOM_Developing WBS & Risk Register for “Our Lovely House Brownfield Project” by using Humphreys Earned Value Project Management Technique


1. Problem Definition

Refer to my W9 Blog (https://simatupangaace2014.wordpress.com/2013/11/07/w9_tom_setting-up-our-lovely-house-brownfield-project-by-using-humphreys-earned-value-project-management-technique/), I have finished the step 1 – Identifying Project Objective and already proceeded into Step 2 – Work Scope Definition and Risk Assessment. The problems to be solved in this W10 blog are creating the WBS and do the Risk Assessment.

2. Development of Feasible Alternative

As presented in my W9 blog that I will try to develop my project WBS by using OmniClass Classification System (OCCS).

As shown in Figure 1 that there is various OmniClass WBS type and as recommended by my AACE Class mentor Dr. Paul D. Giammalvo then I will use Table 22 – Work Results.

To develop my Project Risk Register, the best reference is Humphreys Project Management using Earned Value Book as shown by example in Figure 2.

3. Development Outcomes for Alternatives

WBS:

Figure 3 is showing the List of Standardized Level 1 WBS and I need to identify which of the list that most likely suitable to be adopted into my Project Level 1 WBS.

Risk Register:

Humphreys said that the identification of project risk is the single most important activity and arguably. The most difficult activities in the project is managing the project risk. Identifying project risks can take many paths such as project assumptions, risks experiences from previous similar projects, industry sources, expert opinion, Earned Value Management System Variance Analysis Reports, lesson learnt on similar project, brain storming, Delphi analysis, company list management guidance and procedures. The most excellent source of risk exposure from the present project is risks experienced from previous project.

Fortunately I had previous house renovation project experience (although it is in smaller scale) to list down potential list of my forthcoming project. Based on it I have listed down the risk as shown in Figure 4.

4. Selection of Criteria

WBS:

By adopting OmniClass Table 22 Level 1, I have developed my level 1 project WBS as shown in Figure 5.

Risk Register:

I will continue completing my Risk Register (Figure 4) after I have finished developing Level 3 WBS.

5. Analysis of the Alternative

I have 2 (two) options whether to classify my level 0 WBS into 2 headers which are Kitchen Renovation and Car Port Construction or just classify into 1 (one) header which is House Renovation Project. By having 2 headers meaning that it will be like having 2 sub-projects under the main project and each project will have individual phase breakdown.

Just having 1 header in Level 1 WBS it will create less complicated WBS (kitchen renovation and car port is combined into one phase) however I will not be able to see full breakdown of each header and at the end I will not be able to know how much duration and cost of each header/sub-project.

6. Selection of Preferred Alternative

If my preference on the contract strategy is provisional sum (at cost) contract then separate the level 0 into 2 (two) sub-project is the best option since it gives better to prepare the cost estimation.

If my preference on the contract strategy is lump sum contract then not to separate the level 0 into 2 (two) sub-project is the best option since the EPC Contractor who will be executing most of the works as well with the cost.

7. Performance Monitoring & Post Evaluation Result.

I have not decided yet regarding the contract strategy whether it will be a provisional sum or lump sum contract project and hopefully after I have finished the 6th step of the Project Management using Earned Value process. In the coming W11 Blog my expectation is that I already came out with a Level 3 WBS.

  1. Nice work, Tommy!!! You are developing the step by step process perfectly following Humphrey’s…..

    My only challenge to you would be to compare Humphrey’s Risk Register against the one I provided to you? (see day 3, slide #53?) What do I have in my recommended template that Humphrey’s DOESN’T have? What does Humphrey’s template have that I DON’T have?

    I will send you out the Excel template under separate cover so you can compare them and see which one you like or prefer most. You might also want to Google on “Risk Templates” and “House Construction” and see if you find anything the either Humphrey or I are missing….?

    Keep up the good work on this simple but very appropriate case study.
