Teach you how to manage project time breakdown in three steps

　　The project time is limited, so reasonable configuration and management are needed to better ensure the project is completed on schedule. To manage the project time, it is necessary to list the work involved in the project as much as possible and make careful arrangements. In the limited project time, it is the key to do a good job in the management of project time decomposition by making good use of the project personnel and property conditions and doing the best possible job decomposition. The following content will teach you how to manage project time breakdown in three steps.

　　1. Definition

　　of decomposition of project work into smaller, more manageable work packages, also called activities or tasks, should be detailed and implementable tasks that ensure the completion of the deliverables. In project implementation, all activities should be listed in a clear list of activities, and each member of the project team can clearly understand how much work needs to be processed. The list of activities should be in a documented form for ease of use and management in other processes of the project. Of course, as the decomposition of project activities deepens and refines, the work breakdown structure (WBS) may need to be modified, which also affects other parts of the project. For example, cost estimates may increase when activities are considered in more detail, so when activities are defined, the content of the project work breakdown structure is updated.

　　2. Activity duration estimation

　　Project duration estimation is to list the duration required for project activities according to the project scope and resource status plan. Estimated duration should be realistic, valid and of quality. Therefore, when estimating the duration, it is necessary to fully consider the list of activities, reasonable resource requirements, the ability of personnel, and the impact of environmental factors on the project duration.

　　Generally speaking, the construction period estimation can take the following ways:

　　1) Expert review form. Analysis and evaluation by experienced and competent personnel.

　　2) Simulation estimation. Estimated duration is calculated using previous similar activities as the basis for estimating the duration of future activities.

　　The impact of risk factors on the duration should be fully considered in the duration estimation of each activity. After the project duration estimate is completed, quantified duration estimate data can be obtained, documented, and the activity list refined and updated.

　　3. Sequence of activities

　　On the basis of product description and activity list, it is necessary to find out the dependencies between project activities and the dependencies and work sequence of special fields. Here, it is necessary to consider not only the special order and priority logical relationship desired within the team, but also various dependencies between internal and external, external and external, and some related work to be done to complete the project, such as in the final hardware environment. Perform software testing, etc.

　　In the definition of project activity relationship, four methods are generally used: priority diagram method, arrow diagram method, condition diagram method and network template, and finally a set of project network diagram is formed. One of the more commonly used methods is the priority diagram method, also known as the single-code network diagram method.

　　Setting project milestones is an important part of sequencing. Milestones are key events and key target times in a project, and are important factors for project success. Milestones are an integral part of the sequence of activities that ensure completion of project requirements. For example, in a development project, key tasks such as final confirmation of requirements and product handover can be regarded as project milestones.

　　To do a good job in the three steps of project time decomposition management, such as project definition, activity duration estimation and activity sequencing, these will test the professional knowledge and management experience of the project manager. Do a good job in time decomposition, and use project management software to manage the project implementation process, and project time decomposition management can be more effective. Strictly require project members to do their own work plans and work reports, so that the project manager can timely understand the completion of the project size and work through the project management software, and can better control the project progress and adjust the project plan to ensure the quality of the project and the completion of the project on schedule. .
