Once the project has begun, senior management will require an approximate estimate of how long each stage of the project will take. There are three methods that are commonly used within organizations for giving estimations: top-down, parametric, and bottom-up. The first method is not very accurate but can be useful in giving a rough estimate at the start of the project management process. The parametric system is slightly more accurate in that this process sums the number of work units by the time it takes to complete one work unit. This technique is generally useful when a certain task has previously been completed and thus the new task can be estimated based on that fact. Lastly, the bottom-up method is the most accurate, but every single detail is required to give an approximation on how long a task will take.
In terms of issues that may come up in project management, I feel that lack of clarity plays a huge part in the project not going to plan. At the beginning of the project, if every step is not laid out, then it will be difficult to determine which processes have been completed. A written agreement should be made between the project manager, the project customer, and the project sponsor. This document should identify the project’s objective and how this objective will be met. It may be that the project needs to change slightly once the process has begun. If this is the case, then the change management process needs to be implemented so changes can be made when needed. This leads to the next issue with project management—shifting managerial priorities. The business environment is always changing so there is always the need to change with it. For project managers, this will require pre-planning to account for any future market changes, whether they are internal or external. Projects are largely in the hands of outside forces. One such force may be an incoming company president who orders any current projects to remain on hold. This can potentially slow down the implementation of a project manager’s recommendations. A project manager needs to have open lines of communication with his subordinates and always be ready to change the project plan depending on the situation. Once again, the change management process will be required because it can address the needs of a business at short notice. More specifically, change management has the tools to deal with external changes that the organization has no control over.
To sum up, project management is a vital component of an organization. A big part of achieving this is to appoint the right people for the right positions. All employees involved in the project management process need to be adaptable and open to change.
