Concepts
Project resource requirements play a pivotal role in the realization of a project’s objectives. Gaining a clear understanding of these resources helps in efficient planning, allocation, and management, thereby bringing a project to a successful conclusion. Project Management Professional (PMP) candidates are expected to have a strong grasp of how to deduce project resource requirements, an essential competence that is tested extensively in their certification exam.
Understanding Project Resource Requirements
In the context of a project, resources refer to the individuals, materials, equipment, and time needed for the project’s execution. Correctly identifying these requirements is critical as it determines the project’s cost, timeline, and overall feasibility. The requirements are categorized into four primary types: Human Resources, Material Resources, Equipment, and Time.
- Human Resources: These are the personnel required to perform the work of the project. These can range from project managers, department heads, team members, or even external consultants.
- Material Resources: All tangible materials necessary for project execution compose material resources. These include consumables, office supplies, software, etc.
- Equipment: Infrastructure, machinery, or tools needed to offer support to human resources or facilitate material resources usage are the equipment resources.
- Time: This resource refers to the project timescale, outlining the duration for project completion.
Given the wide range of resource varieties, estimating project resource requirements becomes a significant factor for project success.
Effective Strategies for Deduction of Project Resource Requirements
Use of techniques like Expert Judgement:
Leveraging Expert Judgement involves consulting individuals or groups with specialized knowledge in the relevant area. For example, a software engineer would be proficient at estimating how much time would be needed to write a specific code, or a construction foreman could deduce the perfect amount of concrete needed for a construction project.
Implementation of Analogous Estimating:
This technique leverages data from previous similar projects to deduce resource requirements for the current one. For instance, if a past software development project of a similar framework required four developers and took three months, then a current similar project might have analogous resource requirements.
Employment of Parametric Estimating:
In this approach, statistical relationships between historical data and variables (like scope, cost, duration) are used. For example, on understanding that it takes one hour to test a code of 100 lines and the current project has 500 lines, it can be deduced that five hours of testing time would be required.
Utilizing Three-Point Estimating:
This technique is based on determining three types of estimates (Most Likely, Optimistic, and Pessimistic) and then averaging them to deduce the final estimate. If a designer thinks an architectural design will likely take three days to complete, could possibly be done in two days, and at the worst might take five days, the time resources required equates to three days.
Applying Bottom-Up Estimating:
It involves the estimation of resources at the individual task level, which are then collectively used to deduce the overall project resource requirements. If a website development task requires a designer for five days and a developer for seven days, the total time resource necessary for the project is twelve days.
Comparison of Strategies
Here’s a comparison of these strategies in table form:
| Estimation Technique | Advantages | Disadvantages |
|---|---|---|
| Expert Judgement | Makes use of expertise and specialized skills | Dependence on individuals |
| Analogous Estimating | Useful when project is similar to past projects | May not be accurate for unique projects |
| Parametric Estimating | Makes use of statistical measures and calculations | Requires plentiful accurate historical data |
| Three-Point Estimating | Provides a range of possibilities | Can be overly optimistic or pessimistic |
| Bottom-Up Estimating | Very accurate as it considers each task | Time consuming and intensive |
Understanding and properly employing these strategies ensures efficient resource requirement estimation, a vital aspect in project planning and execution. This is a crucial subject area for those studying for the Project Management Professional (PMP) exam, as deducing project resource requirements successfully plays a key part in project management.
Answer the Questions in Comment Section
The project resource requirements refer solely to the personnel needed to complete a project.
– True
– False
Answer: False
Explanation: Project resource requirements encompass personnel, equipment, materials, budget, and time required to complete the project.
Which of these methods is not used to deduce project resource requirements?
– Expert Judgement
– Bottom-up Estimating
– Grey Squirrel Method
– Analogous Estimating
Answer: Grey Squirrel Method
Explanation: The Grey Squirrel Method is not recognized in project management. Expert Judgement, Bottom-up Estimating, and Analogous Estimating are all used in resource requirement analysis.
Identifying project resource requirements is the first step in project scheduling.
– True
– False
Answer: False
Explanation: The first step in the project scheduling process is the definition of activities. Identifying project resource requirements comes later in the project planning phase.
Which of these would not be considered a component of project resource requirements?
– Software tools
– Trained personnel
– Stakeholder communication
– Work materials
Answer: Stakeholder communication
Explanation: While stakeholder communication is crucial in project management, it is not considered a direct resource requirement like software tools, trained personnel, or work materials.
Project resource requirements analysis is performed only once at the start of the project.
– True
– False
Answer: False
Explanation: Project resource requirements analysis is an ongoing process which is reviewed and adjusted as needed throughout the life cycle of the project.
Include the following in project resource requirements estimation:
– Technical skills
– Cost of materials
– Project timeline
– All of the above
Answer: All of the above
Explanation: All these elements — technical skills, cost of materials, the project timeline — are critical in estimating project resource requirements.
Stakeholder risk tolerance does not affect your project resource requirements.
– True
– False
Answer: False
Explanation: Stakeholder risk tolerance can significantly influence the allocation of resources in a project, including time, money, and personnel.
Bottom-up estimating is good for complex projects with unclear requirements.
– True
– False
Answer: False
Explanation: Bottom-up estimating is more appropriately used for projects with a clear, detailed scope and requirement. Unclear requirements might call for other methods like analogous or parametric estimating.
Resource smoothing is a technique used to adjust the project schedule to meet the organization’s resource capacity and demand.
– True
– False
Answer: True
Explanation: Resource smoothing is indeed a technique by which project schedules can be adjusted according to available resources.
Resource leveling is a technique used to balance demand for resources with the available supply.
– True
– False
Answer: True
Explanation: Resource leveling is a schedule adjustment method that allows a project manager to balance the demand for resources with the available supply.
Project resource requirements should be re-evaluated and updated after every project lifecycle phase.
– True
– False
Answer: True
Explanation: Project resource requirements should be reassessed and updated as a project moves through its lifecycle to ensure the accuracy and efficiency of resources used.
The project manager alone is responsible for deducing the project resource requirements.
– True
– False
Answer: False
Explanation: While the project manager plays a vital role in settling project resource requirements, this task is usually a collective effort involving team members, stakeholders, and sometimes external experts.
