These techniques become necessary when projects fall behind schedule or when stakeholders require earlier delivery dates. There are two primary schedule compression techniques recognized in project management: crashing and fast-tracking.
Crashing involves adding extra resources to critical path activities to reduce their duration. This typically means assigning additional team members, authorizing overtime, or bringing in external contractors. While crashing can effectively reduce the schedule, it almost always increases project costs. Project managers must carefully analyze which activities will provide the greatest schedule reduction for the least additional cost. The key is to focus crashing efforts on critical path tasks, as compressing non-critical activities will not shorten the overall project duration.
Fast-tracking involves performing activities in parallel that were originally planned to be done sequentially. For example, if design and development phases were scheduled consecutively, fast-tracking would have them overlap. This technique can significantly reduce the project timeline but introduces additional risk. When activities overlap, there is potential for rework if earlier activities produce changes that affect later ones. Fast-tracking also increases complexity in coordination and communication among team members.
Project managers should consider several factors when selecting compression techniques: available budget, risk tolerance, resource availability, and the nature of the activities involved. Often, a combination of both techniques yields the best results. It is crucial to document the impacts of these decisions and communicate changes to stakeholders.
Both techniques have trade-offs. Crashing increases costs while fast-tracking increases risks. Neither technique can guarantee success, and both require careful planning and monitoring. Understanding when and how to apply these techniques is fundamental knowledge for project managers seeking Project+ certification and demonstrates competency in managing project constraints effectively.
Schedule Compression Techniques
Why Schedule Compression Techniques Are Important
Schedule compression techniques are critical project management tools that allow project managers to shorten the project timeline while maintaining the original project scope. In real-world scenarios, projects often face delays or stakeholders may request earlier delivery dates. Understanding these techniques is essential for the CompTIA Project+ exam and practical project management success.
What Are Schedule Compression Techniques?
Schedule compression techniques are methods used to reduce the overall duration of a project schedule. There are two primary techniques recognized in project management:
1. Crashing Crashing involves adding resources to critical path activities to reduce their duration. This typically means adding more people, equipment, or working overtime. The key characteristic of crashing is that it usually increases project costs. When crashing, project managers focus on activities that provide the maximum schedule compression with the minimum cost increase.
2. Fast Tracking Fast tracking involves performing activities in parallel that would normally be done in sequence. This technique takes advantage of overlapping phases or tasks. While fast tracking does not necessarily increase costs, it does increase project risk because tasks that depend on each other are being performed simultaneously.
How Schedule Compression Works
To apply schedule compression effectively:
1. Identify the Critical Path: Focus compression efforts on critical path activities, as these determine the project end date.
2. Analyze Options: Evaluate which technique is most appropriate based on budget constraints, risk tolerance, and available resources.
3. Calculate Trade-offs: For crashing, determine the cost-per-day saved. For fast tracking, assess the additional risks introduced.
4. Implement Incrementally: Apply compression in small increments and reassess after each change.
5. Monitor Results: Track whether the compression is achieving desired results and adjust as needed.
Key Differences Between Crashing and Fast Tracking
- Crashing = More resources = More cost = Same or similar risk - Fast Tracking = Parallel activities = Same or similar cost = More risk
Exam Tips: Answering Questions on Schedule Compression Techniques
1. Remember the Cost-Risk Association: If a question mentions budget concerns or cost increases, think crashing. If it mentions increased risk or rework potential, think fast tracking.
2. Critical Path Focus: Compression only works on critical path activities. If a question asks about compressing non-critical activities, recognize this will not shorten the overall project duration.
3. Look for Keywords: Questions containing words like 'additional resources,' 'overtime,' or 'more staff' point toward crashing. Words like 'parallel,' 'overlap,' or 'concurrent' indicate fast tracking.
4. Understand Limitations: Neither technique can compress a schedule indefinitely. There are practical limits to how many resources can work on a task and how much overlap is possible.
5. Scope Remains Unchanged: Both techniques maintain the original project scope. If a question suggests reducing features or deliverables, that is scope reduction, not schedule compression.
6. Scenario-Based Questions: When presented with a scenario, first identify the constraint (budget or risk tolerance), then select the appropriate technique.
7. Common Exam Trap: Do not confuse schedule compression with scope changes or quality reductions. The exam may present options that reduce scope as schedule solutions, but these are not compression techniques.
