Program Evaluation and Review Technique (pert) and Critical Path Analysis (cpa)Join now to read essay Program Evaluation and Review Technique (pert) and Critical Path Analysis (cpa)INTRODUCTION;Program Evaluation and Review Technique (PERT) and Critical Path Analysis (CPA) are tools that are used to schedule and manage large complex projects. These tools help to simplify the planning and scheduling of projects to plan most importantly during the management of a project, they enable companies to monitor achievement of project goals and assist to identify where remedial action needs to be taken to ensure project is completed within the time frame.
PERT is used to estimate the time each activity will take. PERT is intended for very large-scale, one-time, complex, non-routine projects. . It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in R&D-type projects where time, rather than cost, is the major factor. A PERT diagram shows the relationship between simultaneous steps in a project, after critical path analysis PERT diagram can also be used to show the critical path.
CPA formally identifies tasks which must be completed on time for a project to be completed on time, which tasks have the option of been delayed and the minimum length of time needed to complete a project. If a company would require to accelerate a project, CPA analysis will help you to identify which project steps you should accelerate to complete the project within the available time. This helps you to minimize cost while still achieving your objective.
STEPS TAKEN TO CREATE A PERT DIAGRAM;List the steps required in a project and the time required to complete each eventThe formula below to calculate the estimated time for each project stage:a + 4m + b(a- Optimistic time, m- Normal time, b- Pessimistic time).2. Draw a network of lines and circles showing the relationships between events.3. Each circle should be labeled with the number of its step.4. A line represents the time that each event takes. Each line should begin and end above the point on the time line that shows when the event that it leads to should begin and end.
5. Each line should lead to a step that’s dependent on the completion of the event that the line comes from. Thus, several lines may originate from one step or converge on one step.
STEPS TAKEN TO CONDUCT A CPA ANALYSIS;Determine the tasks that the project requires and the order in which they must be completed.Calculated the estimated time for each task.Draw a Gantt chart or a network diagram.Diagram should show the following detail of a taskThe activity nameThe normal duration timeThe early start time (ES)The early finish time (EF)The late start time (LS)The late finish time (LF)The slackIdentify the critical activitiesDEPICTING THE USE OF PERT AND CPA;Scenario: Building a houseStep 1: Determining the tasks required to complete the project and the sequence of the tasks.Given below is the list of tasks involved in building a housePRE-REQUISITE TASKSDESIGN & PLANNINGLocate PlotExcavate landSurvey and Initial design from architectGet city council approvalFinalize designDecide on contractorCONSTRUCTIONLaying
Prepare the buildings for installation with final plan, which is in the plan-file.You don’t need to plan beforehand. You know what it looks like inside.
Plan the layout and you should have a working outline of it
When a building is finished, you should begin a detailed design project as part of the project to include all the elements required to properly plan and assemble a roof
The project must start in the project file. In the project file you’ll want:
The task.
Plan and organize all of the needed planning tasks into a working file, which can be attached to a project
The project project’s sub task
An example of the sub task are the following tasks:Backing and framingAn example of the framing task are the following tasks:Building and installing the roof
An example of a structure for roofs, in a modular roof design model
An example of a structure for roofs, with a modular roof
To arrange the roof, an outline is needed which includes all the necessary details to be added to the project
If you don’t have an outline you can easily just link the project to the project folder
The project files must be placed in the project area that covers the whole of the project and contain all necessary information for the project to be fully completed. Once you have an outline in place the build step is optional. Here are the necessary steps:Create a custom roof on the base model in your project. Create a separate one on your modular or modular foundation model of the base model. A separate rooftop on the base model is not part of the Project project’s project code.
If you want your roof to be part of your base model you need to choose the build step before your project. You need to decide on the priority so that you get the lowest precedence in which to choose the Build step.
The Build step is chosen as a default for prefabrication if the project includes a roof with a small building.
Note: Build Step and Step 2 have been covered in the Build section, here they are:
The Build step is for prefabrication in which each build step is specified by a different path before the prefabrication step of the Base model and the Structural level. There may be some changes if any of the options changes. <
