Project Manager case manual Study Series [6]-develop implementation plan

Once a suitable strategy is selected for the project, a detailed approach to implementing the Strategy must begin. The work breakdown structure (WBS) is the most important tool in project management. The work breakdown structure lists all the tasks that must be done in the project to meet the requirements.

6.1 prepare and use the work breakdown structure

The work breakdown structure can be used to identify all tasks, and the integrity of the breakdown structure can be reviewed by all project stakeholders before other plans are developed.

Form of work breakdown structure

There are two types of Work Breakdown structures: one is similar to the organizational structure diagram, but the box indicates work activity 2 is not the structure, and the other is the form of work breakdown structure.

Organizational structure:

Straight-line contraction form:

The typical work breakdown structure is six levels, and more than six levels are acceptable.

When doing a work breakdown structure, you do not need to consider the order of each task. You only need to list the tasks.

6.2 work breakdown structure Overview

• Up to 20 levels
• There is no need to break all directions in the work breakdown structure into the same level.
• All the next-level tasks under a subtask are completed, and the subtask is completed. In addition to this meaning, the work breakdown structure is not realistic. The sequence is determined when a plan is made.
• The work breakdown structure should be done before the task is planned and the resources are allocated.
• The work breakdown structure should be prepared by personnel who know the work.

6.3 estimated time, cost, and resource requirements

Estimation is never a simple task. The higher the risk level, the more anxious the work. However, if the estimation problem is not well managed, the project will never be completed on time and within the budget.

Parkinson's Law: work continues to extend to the allowed time.

Estimation addition: project members always require more time than the average time, because the more time allowed, the easier the work, and the higher the probability of success.

6.4 other factors in Estimation

Other factors include: Skill proficiency and experience of personnel, and the effective time for project members to work (the effective time does not include meetings and training ).

Estimation Method:

1. Consensus Estimation Method: project members participate in estimation and take the time that everyone can accept.
2. Average table: calculate the average time required to complete a job based on the company's historical data.

6.5 use Cortana for work breakdown structure Encoding

Each scheduled task in the project is assigned a time report when a person executes a task, it indicates how many hours they have spent and how much work they have done. This type of report provides good control over the project and allows you to create historical databases over time.

6.6 linear responsibility table

After completing the work breakdown structure, enter a linear responsibility table to indicate who is responsible for a specific task.
