Summary by Senior Project Manager-Project Control

Range control

L Scope change control tools and methods include scope change control system, performance measurement, and supplementary plan preparation.

L performance measurement is used to help assess the degree of deviation. There are many related technologies, such as performance review, deviation analysis, trend analysis, and earned value analysis.

L factors that affect scope changes include:

1. Strategic Adjustment of enterprises;

2. The project requirements have changed;

3. Technological Revolution;

4. Resource Conflict;

5. Changes in the operating environment;

L The purpose of the project scope management plan is to analyze the reliability and stability of the project scope.

L project scope validation is a process in which project stakeholders formally accept the scope of the project. deliverables and work results need to be reviewed to ensure that they have been completed correctly and satisfactorily.

L project scope validation should be performed by all key project stakeholders. Therefore, key project stakeholders should know the scope of the project and deliverables to be submitted by the project.

L coordination of implementation of multi-objective scope plans should be achieved in the following six aspects:

1. priority;

2. Scope change;

3. Resource Plan;

4. Document work;

5. Project staggered work;

6. Organizational structure;

Change control

L overall change management aims:

1. Check whether changes made during the project process constitute changes;

2. exert some influence on the various factors that cause changes to ensure that these changes occur in the desired direction;

3. When a change actually occurs, the actual change is managed;

L performance measurement is used to help assess the degree of deviation, identify the cause of the deviation, and determine whether the deviation requires corrective measures, and then determine whether to take changes. There are many performance measurement techniques, such as performance review, deviation analysis, trend analysis, and earned value analysis.

L The methods used for project change control include the information feedback system, control system, and organization implementation system.

L The project change control system is a set of procedures to be followed when modifying project documents, including written documents, tracking systems and change approval systems, including measures, information and feedback.

L The change control and overall project and other change control methods within the project scope are universal and mainly include the information feedback system, monitoring system and organization implementation system.

L The specific control work is mainly completed through the control system. There are mainly three tools and technologies used in this process: Scope change control system, performance measurement, and supplementary plan preparation.

L there are many performance strategy technologies, such as performance review, deviation analysis, trend analysis, and earned value analysis. From blog.csdn.net/caisini_vc

Progress Control

L basic methods for adjusting project progress:

1. Change the logical relationship between related jobs;

2. Change the duration between related jobs. You can shorten the total duration of the Schedule by adding resources for key jobs on key lines and shortening the duration;

3. Change the start time and end time of work;

4. Improve equipment and labor productivity;

5. Subcontracting of some tasks;

L project progress report is the simplest written report for recording inspection results, project progress status quo and development trends. It is generally divided into a project summary-level progress control report (a report that describes the implementation of the progress plan for the entire project) project management-level progress control report (Report on the Implementation of the progress plan by Project) and business management-level progress control reports (reports written for a key part or key issue ).

L The most basic analysis of progress deviation is to analyze and compare the deviation between the actual progress and the planned progress. The commonly used method of comparison analysis is chart representation. The commonly used chart comparison method is as follows:

1. crosstab chart (Gantt chart)

 

2. S-type curve

 

3. Banana Curves, etc.

 

L adjustment of the project progress plan:

1.Key work adjustments;

A) Adjustment Method when the actual progress of key work is compared with the advance progress;

B) adjustment methods when the actual progress of key work is relatively low;

2. Change the logical relationship of some jobs;

3. recompile the plan;

4. Adjustment of non-critical work;

5. add or remove work items;

L The project progress change and control system describes the process of project progress change, which includes paperwork, handling process and improvement measures. The project progress change control is based on the project progress plan, Progress Report, change request, and Progress Management Plan, and is implemented through the progress change control system.

L a line with a negative time difference is the key to correcting the project progress.

L The key to effective progress control is to focus as early as possible on the line with negative time difference or deviation from progress.

L common methods to resolve conflicts include:

1. Establish methods and procedures for resolving conflicts within the enterprise;

2. Establish guidelines and procedures for resolving project conflicts during the project planning phase;

3. Use superiors to resolve conflicts;

4. Both parties have a positive attitude towards solving the problem and communicate with each other;

L The five basic conflict resolution policies include:

1. Withdrawal or withdrawal;

2. competition or coercion;

3. Easing;

4. Compromise;

5. Face to face;

Cost Control

L expense audit can be arranged according to the project's life cycle or milestones, which are generally divided into the following three phases:

1. Expense audit during the project planning period. Audit basis: project description, feasibility report, work breakdown structure, cost estimation and budget. Audit results: Expense audit report for the project planning period.

2. The audit basis in the audit of cost reports during the project renewal period: Cost Report, process report, and quality report. Audit results in the cost report audit: audit reports during the project renewal period. Audit basis in implementation cost audit: cost report, Progress Report, quality report, etc. Audit results in implementation cost audit: implementation cost audit report during the project renewal period.

3. Audit of costs during the project renewal period. Audit basis: cost report, Progress Report, quality report, cost and resource plan. Audit Result: The audit report for the project's remaining period.

LEarned Value Method, Mainly using three billing values for analysis:

1. Completed work budget cost bcwp

2. planned completion of work budget cost bcws

3. Actual cost of finished work acwp

 

L when a fee exception occurs, two types of work should be rectified:

1. work to be done in the near future;

2. Work with a high budget;

L estimate the cost when the project is completed (EAC)

1. EAC = actual expenditure + changes made to the remaining budget based on the current situation;

2. EAC = actual expenditure + re-estimate the remaining work in the future;

3. EAC = actual expenditure + remaining budget;

Quality Control

L prevention and check: The purpose is to exclude errors from the process, and the check is to exclude errors before they are delivered to the customer.

L there are many types of accidental factors that often affect the product quality. However, they do not have a great impact on the product quality and will not cause waste products. Differences caused by accidental factors, also known as instant errors, are neither easy to identify nor eliminate, or economically worthy of elimination. Accidental factors include slight differences in raw materials, normal wear and tear of equipment, smiling changes in workers' operations, and slight fluctuations in temperature and humidity.

L system factors such as incorrect raw material specifications and varieties, failure of machinery and equipment, and operation not in accordance with regulations. This type of factor has a great impact on quality and can cause waste and defective products. Such factors are easy to identify and should be avoided.

L quality control tools:

1. An exclusive chart, also known as a Paret chart, is a method to find the primary and secondary factors that affect quality.

 

2. the causal analysis diagram, also known as the Fishbone Diagram, is a graphical method for gradually researching and discussing quality issues.

3. histogram, which describes the distribution range and features of mass frequencies.

 

4. The control chart, also known as the management chart, is used to analyze whether the quality fluctuation is caused by a normal cause or by a single cause, so as to determine whether the production process is under control. There are usually three lines in the figure. The above dotted line is called the upper control line, which is represented by UCL. The lower part is called the lower control line by dotted line, and the middle part is called the center line, which is represented by Cl.

 

5. A scatter chart, also known as a correlation chart, is a method for analyzing, judging, and studying whether there is a correlation between two corresponding variables and clarifying the degree of correlation.

 

6. hierarchy.

7. questionnaire form.

L corrective actions are the reason for the occurrence of nonconforming products, or the occurrence of nonconforming items found during internal audits or external audits or any other monitoring activities, take measures to eliminate the cause and prevent the occurrence of the fault again. Risks, benefits and costs should be weighed to determine appropriate corrective actions.

L preventive actions are taken to eliminate potential nonconformities or other potential undesirable situations.

L The relationship between quality management plan and control is that quality management plan is the control standard and basis, and control is the guarantee during the implementation of quality management plan. Without control, it is difficult to implement the quality management plan.

L quality trend prediction method:

1. Qualitative analysis, also known as the intuitive method, is simple and easy to use. The main form is the survey meeting or forum.

2. Quantitative Analysis. Any method that uses the measured data to speculate on the quality development trend is called the external method, which is commonly used with time series analysis. The causal method is commonly used to predict the trend of quality development by using the causal relationship between internal factors of things. From blog.csdn.net/caisini_vc

Communication Control

L information has the characteristics of authenticity, level, value type, delay and incompleteness.

L project progress reports generally include daily reports, exception reports, and special analysis reports. Special analysis reports are often used to publicize the project (especially the project's research results) or to comment on some issues that occur during project implementation.

L The methods for preparing the project progress report include progress report, cost report, and comprehensive report:

1. The progress report method uses multiple methods to report progress information. The most common methods are crosstab chart, milestone chart, key route chart, and banana graph.

2. The most common expense report method is the expense report table and S-type curve.

3. Comprehensive report. From blog.csdn.net/caisini_vc

Risk Control

L project risk monitoring is to track identified risks, monitor residual risks and identify new risks, ensure the implementation of risk plans, and evaluate the effectiveness of risk reduction.

L Establishment of Project Risk Monitoring System, this includes formulating the project risk monitoring policies, project risk control procedures, project risk responsibility system, project risk information report progress, Project Risk Warning System, and project risk monitoring communication procedures.

L the internal environment of the project includes customers, suppliers, and contractors.

L The environmental variables, management variables, and weights of each project are different.

L there are two types of risk prediction methods:

1. Qualitative Analysis Method

A) Risk Rating

B) subjective scoring method

C) Analytic Hierarchy Process

2. Quantitative Analysis method from blog.csdn.net/caisini_vc
