Differentiate between resource smoothing and resource levelling

Question 1

Resource Smoothing

Answer 1

• Used when the time constraints take priority
• The objective is complete the work by the required date while avoiding peaks and troughs of resource demand
• Resource levelling is used when limits on the availability of resources are paramount
• Time-limited scheduling; time is relatively more important than cost
• Can be applied to ensure that resources are used as efficiently as possible
• Involves utilising float or increasing/ decreasing resources for specific activities
• Peaks and troughs of resource usage are evened out
• Does not affect project duration

Question 2

Resource Levelling

Answer 2

• Technique in project management that overlooks resource allocation and resolves possible conflict arising from over-allocation
• When project manager undertake a project, they need to plan their resources accordingly
• Resource-limited scheduling
• Applied when there are resource constraints
• Forces the amount of work not to exceed the amount of resource available
• Asks the question ‘with the resources available, when will the work be finished?’
• Can result in durations being extended or delayed at both activity and project level
