A planning horizon, in the context of project management and planning, refers to the time period during which a project or plan is expected to be executed or implemented. It is crucial in determining the scope and duration of the planning process, as well as in establishing milestones and deadlines. When considering the planning horizon, it is essential to consider both short-term and long-term goals and objectives.
To better comprehend the concept of a planning horizon, let’s examine an example within the context of a construction project. Let’s say a company intends to construct a new office building. The planning horizon for this particular project might extend over several years, commencing from the initial design phase and culminating in the completion of the construction process. Throughout this duration, it is necessary to carry out various activities, including obtaining permits, conducting feasibility studies, hiring contractors, and procuring materials.
One method to present the planning horizon for the construction project is by using a table as shown below:
As depicted in the table, the planning horizon for the construction project encompasses the period from January 2023 to August 2025. This timeline offers a comprehensive overview of the different project phases, along with their respective start and end dates.
The planning horizon assumes a vital role in establishing the timeline for project execution. It ensures that all essential activities are accomplished within the designated timeframe, facilitating effective project management and successful project completion.
To comprehend the significance of resource allocation in project management, let’s examine a table that compares the resource allocation strategies for Progressive Elaboration and Rolling Wave Planning:
|Rolling Wave Planning
|Iterative and incremental
|Allocated as needed
|Allocated in advance
|Only for current phase
|Entire project duration
|Minimized in early phases
|Higher in later stages
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 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.
