Project time (Project Schedule Control) Notes

Project Progress control is to continuously track, compare, analyze and adjust the project progress based on the project progress plan and the actual progress of the project, so as to ensure the realization of the project objectives.

Schedule control is one of the three major objectives in the project implementation process, tied to quality control and cost control. It is the last part of time management.

Project progress plan controlFinal GoalIs to ensure the implementation of project progress, cost and quality objectives. Project Progress is generally divided into the following situations:

1. Set up goals by project implementation stage

2. Set up by sub-projects included in the project

3. Set Goals by project implementation unit

4. Set the score by Time

Implement project schedule controlGeneral Process: Project (benchmark) plan ---> project tracking-> project control and feedback are the general principles of project plan control.

 

Progress tracking system

The core of the project tracking system is to timely and accurately reflect the actual changes in the project progress and provide various information reports on the project progress.

The main functions of the project tracking system include: establishing a project progress tracking organization system, determining the collection methods of project progress information, implementing photo album inspection, and holding project on-site meetings.

In order to fully and accurately understand the progress, the project manager must conscientiously do the following three tasks:

1. regularly and periodically collect progress report data

2. Send inspection (Supervision) personnel to the site to check the actual implementation of the Progress

3. Hold regular project on-site meetings

How to collect project progress information

1. Sending Frequency Statistics

2. Raw Data Record sending

3. Empirical Method.

4. Indicator Method.

5. Oral Determination

Content and system of project progress report

The purpose of the project progress report is to timely reflect the project progress and internal and external environment changes, discover existing problems and changes, and analyze potential analysis and forecast development trends, so that the project manager or project management personnel can make correct judgments and decisions to achieve effective project control.

1. Report details

2. Report Frequency

3. Report time point.

Project Progress Report Form

1. Daily (or weekly, ten-day, monthly) Progress Report

2. job status table

3. Problem tracking table

Problems in the project progress report

1. Report responsibility line

2. authoritative line of the report

3. report details

4. Report Economics

5. Information system compatibility

6. control correspondence planned

Two methods to obtain project information

On-site inspection

On-site meeting

Project tracking process

1. Observe

2. Measurement

3. Analysis

4. Report

Deviation Analysis Technology

The deviation analysis technology is a method that intuitively compares and analyzes the actual progress and progress baseline of a project using graphs.

Gantt chart comparison method

It is an intuitive and easy-to-use deviation analysis method. Gantt chart comparison method is one of the simplest and most familiar methods for project schedule control.

1. Comparison Method of uniform Gantt chart.

2. Comparison of Two-proportion one-side Gantt Chart

3. two-sided Gantt chart comparison method.

Limitations:

1. When there are a large number of activities, the preparation of the progress plan is troublesome.

2. The logic between activities cannot be clearly expressed, and key activities and routes cannot be determined. Therefore, key management is not convenient.

3. When there is a deviation in the activity progress, it is difficult to predict its impact on subsequent activities and the overall progress plan, and the adjustment method cannot be determined.

Project Progress change

There are many factors that lead to project progress changes, such as human factors, technical factors, financial and equipment factors, financial factors, climate factors, and environmental factors. Generally, human factors are the most important interference factors.

1. Uncertainty in technical requirements during project implementation

2. incorrect estimation of project characteristics and conditions for project implementation

3. modify the scope of the project during project implementation.

4. the deliverables for the project implementation process and project output are constantly changing.

5. mistakes made by members of the project organization.

6. Unforeseen events

Project Progress Change Control System

Changes to the project schedule may affect the project progress as follows:

1. add and delete project activities

2. Re-Sort project activities

3. Estimated change of project activity duration or update of project requirement completion time

4. Re-calculate the Network Time of the project activity

5. Resource allocation (human, material, and capital.

Project Progress Control

The main methods include the administrative method of progress control, the economic method of progress control, and the management technical method of progress control.

The progress control system must contain at least five elements.

1. Establish System (target) standards.

2. Get the latest progress in time.

3. Progress deviation analysis and evaluation.

4. Take corrective measures in a timely manner.

5. Notify all relevant departments in a timely manner.
