In the case of Progressive Elaboration, resource allocation is carried out as required throughout the project. This approach allows for high flexibility as resources are allocated based on the specific requirements of each phase. Effort is gradually increased as the project progresses, and risks are minimized in the early stages.

On the contrary, Rolling Wave Planning involves pre-allocating resources for the entire project duration. This approach provides less flexibility as resources are allocated upfront based on the initial project plan. Effort tends to be front-loaded, with more resources allocated in the early stages. Risks are higher in later stages as accommodating changes may be more challenging.

When choosing between Progressive Elaboration and Rolling Wave Planning, consider the required level of flexibility, the project’s nature, and the availability of resources. Progressive Elaboration is suitable for projects with evolving requirements and a need for adaptability, while Rolling Wave Planning works well for projects with well-defined scope and stable requirements.

In summary, resource allocation is a critical aspect of project management. The decision between Progressive Elaboration and Rolling Wave Planning relies on the project’s specific needs and objectives. Proper resource allocation ensures that adequate resources are allocated at the appropriate time, leading to the successful completion of the project.

Risk Management

Risk management is an essential aspect of both progressive elaboration and rolling wave planning. It helps to identify potential risks and develop strategies to mitigate or address them.

  • Identify risks: During the planning phase, it is important to identify all potential risks that could impact the project. These risks can include financial risks, technical risks, operational risks, or external risks.
  • Assess risks: Once the risks are identified, they should be assessed to determine their potential impact on the project. This involves evaluating the likelihood of the risk occurring and the severity of its impact.
  • Develop risk management strategies: Based on the assessment, appropriate risk management strategies should be developed. This may include avoiding the risk, transferring the risk, mitigating the risk, or accepting the risk.
  • Implement risk management measures: The identified risk management strategies should be implemented to reduce the likelihood or impact of the risks. This may involve implementing contingency plans, allocating additional resources, or implementing monitoring and control measures.
  • Monitor and review risks: Throughout the project, risks should be continually monitored and reviewed to ensure that the risk management strategies are effective. Adjustments should be made as necessary to address any new or changing risks.
