Over the years, project managers have learned an important lesson: projects often need more resources. Things change – like the project’s scope, employees leaving, or clients changing their minds. These changes can leave you with fewer resources than planned.
Sometimes, projects don’t go as expected. You might not have enough people or tools to finish the job. That’s where “resource leveling and smoothing” comes in. It helps you adjust the project timeline so that you can finish it using the resources you have. This technique lets you manage resources in a way that makes sure the project goals are still met, even if things don’t go as planned.
Resource Leveling
Resource levelling is like a juggling act in project management. It’s a method to make sure nobody on the team gets overwhelmed with too much work at once. Instead, it spreads the tasks out evenly over the project timeline.
This technique adjusts when different tasks start and finish. It considers things like how many people are available when they’re free to work and which tasks need to be done first. It’s a way to balance the workload and keep things running smoothly.
Explanation
Resource levelling is a smart way to prevent people or materials from being overwhelmed, making projects run smoother. It’s like making sure nobody takes on too much work or materials at once, which could slow things down.
This technique is needed when important resources like people or materials are only available at specific times or in limited amounts. It helps avoid giving too much work to one person or using up all the resources too quickly.
For example, if a resource can only work for 8 hours a day, and you’ve planned more work than that, you’ll need to adjust things. This adjustment could mean changing the project schedule.
Let’s say you have a 7-week project, but applying the 8-hour constraint might extend the project to 9 weeks to manage the workload better. This technique helps keep everything balanced and running smoothly, even if it changes the project’s timing.
Using a Project TimeTracking tool like TimeTrack aids in understanding the impact of these adjustments on the project timeline. By observing TimeTrack data, one can effectively assess how the workload changes throughout the extended project duration. Despite the shift in the project timeline due to the constraint application, the TimeTracking tool helps maintain a balanced workload, ensuring that tasks are appropriately distributed among team members.
How to Use
- If you have the freedom to change how long a project or its phases take, resource levelling can be effectively applied to balance workloads.
- When you have the ability to modify the critical path, resource levelling can help, as it might involve reorganizing tasks and timelines.
- When resources are stretched thin, but additional resources cannot be added, resource leveling becomes a crucial approach.
- This method works best when you’re dealing with limitations in resources, allowing you to manage tasks within those limitations without affecting project quality or timeline.
Resource Smoothing
Resource smoothing is like fine-tuning a project plan. It’s a method in project management that helps organize resources better without making the project last longer.
Once resource leveling has balanced out the workload, resource smoothing steps in. Its goal is to make sure the resources needed fit within certain limits without stretching the project timeline. This technique focuses on adjusting the schedule in areas where there’s room to maneuver, making sure the workload stays well-balanced. By making strategic tweaks in the more flexible parts of the schedule, resource smoothing aims to make resource allocation more efficient and improve how the work gets done.
Explanation
Resource smoothing is about making resource use more balanced over time. While resource leveling spreads out the work over the whole project, resource smoothing looks at keeping a realistic and manageable workload. It considers things like breaks, non-project tasks, or other responsibilities connected to the project.
It understands that making someone work on project activities for the entire 8 hours of the day might not be practical or efficient. So, resource smoothing helps project managers adjust how resources are used. It allows some flexibility in scheduling daily activities while still meeting the project’s needs. The goal is to make the most of resources and create a better, more manageable project plan.
Imagine a project that was initially set for 7 weeks but extended to 9 weeks to fit in the maximum available time of 45 hours. To meet the target of 38 hours per week, further adjustments are necessary to optimize how the time is used.
How to Use
- Begin by assessing the current workload distribution among resources. Identify areas where work is concentrated and where there might be underutilized time or overburdened periods.
- Pinpoint sections within the project schedule that offer flexibility or “float,” where activities can be adjusted without affecting the project’s final deadline.
- Within these flexible areas, reorganize and adjust the schedules of activities or tasks. This could involve minor shifts in timing or small pauses, ensuring a more balanced workload.
- Take into account the limitations of available resources. Ensure that adjustments made align with the capacity and constraints of each resource.
- It’s crucial to communicate with the team about any adjustments made to their schedules or tasks. This ensures everyone is aware of the changes and can adapt their workflow accordingly.
- Continuously monitor the impact of adjustments made through resource smoothing. Fine-tune and make further adjustments as necessary to maintain a consistently balanced workload without extending the project duration.
Utilize the Project Controlling tool by TimeTrack, to monitor these changes. Regularly assess how these adjustments influence the project’s workload distribution and resource allocation. This includes keeping a close eye on TimeTrack data to understand how the alterations impact the balance of work among team members.
Difference between Resource Leveling and Resource Smoothing
Resource Leveling
- Impact on Project Finish Dates: Resource levelling, when implemented, can lead to changes in the finishing dates of the project. By redistributing work among resources, it can cause adjustments in the project’s critical paths, often resulting in an extension of the overall project timeline.
- Critical Path Adjustments: This technique influences critical paths by altering task schedules to balance the workload across the project. As a consequence, critical paths may change, typically increasing in duration due to the reorganization of resources.
- Managing Over and Under Allocations: Resource levelling aims to schedule tasks considering when resources are either over-allocated (assigned more work than available) or under-allocated (not fully utilized). The goal is to balance the workload and optimize resource usage throughout the project.
- Resource as the Key Constraint: In resource levelling, the primary focus is on managing available resources effectively to meet the demands of the project. This approach prioritizes resource allocation and availability as the main constraints.
- Implementation on Critical Path Tasks: Resource levelling is commonly applied to tasks situated on the critical path of the project. It ensures the critical tasks are aligned and adequately resourced to maintain the project’s progression.
Resource Smoothing
- Maintaining Product Finish Dates: Resource smoothing aims to optimize resource usage while keeping the project’s finish dates unaltered. It focuses on balancing the workload without extending the project’s overall timeline.
- Flexibility within Float Boundaries: Activities within their float, the time an activity can be delayed without affecting the project’s final deadline, can be adjusted or paused without impacting the ultimate project delivery date.
- Dealing with Uneven Resource Allocation: Resource smoothing primarily focuses on scheduling activities when resources are unevenly allocated. It aims to ensure a balanced workload across the project without affecting the project’s final delivery dates.
- Project End Date as the Main Concern: The key priority in resource smoothing is to manage resources effectively while keeping the project’s end date constant. The emphasis is on resource optimization without extending the project duration.
- Not Altering the Critical Path: Resource smoothing is performed without altering the critical path. It concentrates on resource allocation adjustments in areas that do not affect the critical path, allowing more flexibility without impacting essential project milestones.
- Performed After Resource Leveling: This technique is typically executed after resource levelling. It fine-tunes the resource usage, providing more efficiency and balance without extending the overall project’s duration.
