Discussion Overview

The discussion centers around a project management problem involving the concept of "crashing" a project to reduce completion time by 4 days. Participants are seeking clarification on how to approach part B of the problem, particularly in relation to a provided table and the critical path of the project.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the definition of "crashing" a project, suggesting it refers to speeding up project completion.
  • Another participant notes that simply subtracting crash time from normal time worked for some activities but not for part B, indicating a potential misunderstanding or error in approach.
  • There is a suggestion to consider immediate predecessors to understand dependencies between activities and which can be worked on simultaneously.
  • A participant asks about the critical path and which tasks on that path are cheaper to speed up, implying that this could affect the overall project timeline.
  • Concerns are raised about the implications of speeding up tasks on the critical path and how it affects project completion.

Areas of Agreement / Disagreement

Participants express differing views on the approach to solving part B, with no consensus reached on the correct method. There is acknowledgment of the need to consider dependencies and critical paths, but specific solutions remain contested.

Contextual Notes

Participants have not fully resolved the mathematical steps involved in determining the correct adjustments for part B, and there are limitations in the information provided regarding the table and critical path analysis.

Who May Find This Useful

This discussion may be useful for students or individuals studying project management, particularly those interested in the concepts of crashing projects and critical path analysis.

By how many days should each activity be reduced the project completion time by 4 days? I have all the parts right except for part B. I thought it was 2 but it's not. What I did was subtract normal time from crash time and it worked for all the problems except B. Here's a link to the table. Any ideas?

A couple questions, or observations:
1. What is "crashing" a project? Is that the term now used to refer to speed up a project towards earlier completion? In economics, or engineering?
2. I feel that what you have done is just subtract the values in crash Time from those in Normal Time. That gave the correct answer for some cases, but apparently not for Activity B.
3. You have to take into account Immediate Predessor to see which activities are dependent upon others, and which activities can be simultaniously worked upon.
4. IF this is homework please POST in homework section
 
What is your critical path?

On that critical path, you have two tasks. Which one is cheaper to speed up?

When you speed that up by the maximum, you now have two parallel critical paths, with four items, but only 3 can be sped up. To advance the completion date, both paths have to be sped up.

What effect does B have on the project completion time?
