W9_Murtadha_schedule compression methods


  1. Problem Definition.

In a previous project I have worked on, company had assigned me as a project engineer for an EPC project of a certain compressor to be used in a flare gas recovery system. Although, the project wasn’t considered a high value it was though considered a high profile project because it was the first of its type for my client.

For this weeks blog I will analyze the schedule compression methods used to help minimize the effects of the schedule overrun.

  1. Identify the Feasible Alternative.

The Following techniques are widely used for schedule compression:

1) Crashing

2) Fast tracking

  1. Development of the Outcome for Alternative

Both techniques provide the same outcome which is to help the project manager to shorten the duration of the project. It is a matter of in what scenario you would use each technique.

  1. Selection of the Acceptable Criteria.

The acceptable criteria are any possible compression in the schedule that would result in shortening the duration of the project.

  1. Analysis and Comparison of the Alternative.

Crashing: this technique implies involvement of additional resources, hence it affects project’s costs. It is based upon an assumption that the project can be accomplished faster when more of workforce and equipment will be engaged into completing its critical tasks

Fast Tracking: This method stands for rearrangement of tasks in the project plan so some of these tasks, which were initially planned to be in sequence, should be executed in parallel. This can be achieved by overlapping of certain project phases and activities.

We have to keep in mind that crashing a schedule increases the cost of the project whereas fast tracking increases the risk.

In my case a combination of both were implemented where we had additional resources flown in to the vendors offices to speed up certain activities and to start other activities so that they can be done simultaneously.

  1. Selection of the Preferred Alternative.

After looking at the analysis above, a combination of the two techniques depending on the scenario you are working on would give you an optimized schedule compression.

  1. Performance Monitoring and the Post Evaluation of Result.

Due to the nature of the changeability in the schedule and how the critical path could change with the slip of a certain activity, it is recommended that  an analysis is carried out at certain intervals throughout the duration of the project.

One thought on “W9_Murtadha_schedule compression methods

  1. Hmmmmmmmm……….. Where is your ANALYSIS? While your case study is a valid and potentially good one, you really didn’t develop it……. WHAT activities did you crash and why? What activities did you fast track and why?

    Also your references are VERY weak…….

    I provided you with perhaps one of the best reference books on scheduling that I have ever seen published- the GAO’s “Best Practices in Scheduling” but you didn’t even bother to cite it? http://www.gao.gov/products/GAO-12-120G Also you have FREE access to AACE’s “Recommended Practices” http://www.aacei.org/non/rps/welcome.asp and there again, I have provided you with some of the best possible references I can find. Compare your references to what I provided you with. SURELY you can do better than that?
