W2_Hilal_GAO Assessment of Schedule (Scoring Method)

By -
Problem Recognition

In our company we receive monthly reports for the project companies and it is important to review and analyze their schedule. However, currently, we are not following any standards or benchmark in order to assess how good or poor is the schedule. Sometimes, not enough information is provided in the schedule or the information misrepresented and all of this can lead wrong analysis of project status. Contractual obligation might be the reason, as we did not specify what to include in the schedule. The GAO assessment of schedule includes ten best practices which can be used as a checklist to assess the schedules we have in hand. Now, we need to develop a checklist that can tells how good or bad the schedule is.

Feasible alternative

The Guild of Project Controls Compendium and Reference suggests two methods for multi attributes decision making. Therefore, these two methods will be used to develop a scoring model which will help us to rate how healthy the schedule is. These methods are:
a.       non-compensatory approach
b.      compensatory approach

Outcomes from alternatives

-          Non- compensatory approach is effective when we are looking for specific features/ attributes. But this will rule out all other features whether they are relevant to assessment or not. In other words, non-compensatory does not trade-off a low value on one criterion against a high value on another attribute.
-          Compensatory approach, in the other hand, will compensate for all the features, therefore, this is effective to account for all features. This approach balances a low value on some criterion against a high value on another criterion.

Acceptance Criteria

The method I am looking for should include the following attributes:
·         Can it be built in excel spreadsheet?
·         Account for all features?
·         How score is calculated?
·         Can it include GAO assessment (ten best practices)?
·         Is it possible to account for HSE performance?
·         Can it provide rating?

Table 1: Analysis of the feasible alternatives

The table above analyze the two approaches against acceptance criteria using weighted method. Column A, shows the importance of the criteria on scale of 1 to 3 where 3 being the most important. Columns B & C represents how the two approaches are meeting the criteria on scale of 1 to 4 where 4 means that it met the requirement.

Preferred Alternative

Based on the results in table 1, we conclude the compensatory approach is the preferred alternative.

Tracking/reporting plan

This alternative is to be used in developing an excel spreadsheet to evaluate the selected schedules.  The spreadsheet will include GAO assessment ten practices and other criterions. This approach will be used to account for all features/attributes in order to use the spreadsheet as a standard evaluation sheet to assess the reported schedules.

    EXCELLENT 1st blog posting on your own. Very well done. Don't forget that there are TWO compensatory options you can choose from so you will have to do another analysis to decide which one is "best" or "better" to use for your analysis.

    Whichever one you choose, what you want to make sure of is that the results will provide you with a true ratio scale which not only will give you the rank order of of the GAO Attributes for assessing the health of your schedules but also the order of magnitude between any two or more of the options. http://study.com/academy/lesson/scales-of-measurement-nominal-ordinal-interval-ratio.html

    This way when you make your recommendations to management, you can show them the relative importance of each of the GAO attributes in the context of what is important to OPWP.

Problem Definition Bruce Tuckman model used to identify the team status and the development phase of the project team. As the team go through these phases, different strategies should be implemented by the team leader and managers. This assessment will provide enough information for the team leader and even for the team members that would give a good understand the team performance.   Identify the Feasible Alternative There were 4 stages model of "forming, storming, norming, and performing" introduced by Bruce Tuckman in 1965. However, a fifth stage was added “adjourning” which describe the phase that the team go through after the achievement of project tasks and completion of the project. Figure 1 , development stages [2] In each phase, the leadership style should be in alignment with that specific phase which enhance the development of the team and improve the performance of the team as well. There are different styles that could be used by the team le...
