What are project management theories?

Project management seems to be based on three theories of management: management as planning, the dispatching model, and the thermostat model. The first is evident from the structure and emphasis of the PMBOK® Guide.

What are project management practices?

What are project management best practices?

• Document project requirements.
• Avoid estimating projects in a vacuum.
• Use a project brief to get stakeholder buy-in.
• Establish a clear project plan.
• Mind your team's workload.
• Clarify project roles and responsibilities.
• Communicate early and often.
• Monitor task progress.

What are the 5 project management processes?

Developed by the Project Management Institute (PMI), the five phases of project management include conception and initiation, planning, execution, performance/monitoring, and project close.

How a project manager selects a project?

The scoring model in project management is an objective technique: the project selection committee lists relevant criteria, weighs them according to their importance and their priorities, then adds the weighted values. Once the scoring of these projects is completed, the project with the highest score is chosen.

What is the difference between PERT and CPM?

PERT is that technique of project management which is used to manage uncertain (i.e., time is not known) activities of any project. CPM is that technique of project management which is used to manage only certain (i.e., time is known) activities of any project.

Can critical path change during project?

The critical path of a project will not remain static throughout its life, it can change during the course of project completion. ... For this reason, the project leader is required to closely monitor the project's activities by comparing the planned progress to the actual progress. ...

Is Critical Path the longest?

Fact: The critical path is the longest path through the network diagram, meaning the sequence of activities that collectivity define the starting and ending dates for the project and have no slack or float time (excess time). Conversely, non-critical paths have slack time which is the amount of time a task can slip.

How do you find the critical path of a project?

Calculating Critical Path is a simple 4-step process.

1. Step 1: Find Activities. Activities for this project are as below (output from Define Activities process) – ...
2. Step 2: Build Schedule Network Diagram. ...
3. Step 3: Find all Possible Paths. ...
4. Step 4: Calculate Duration for Each Path.

What are the advantages of critical path method?

The main benefits of critical path analysis

• It demonstrates the graphical view of any project.
• It helps to identify the most important tasks that you have to manage.
• It helps to save your time and reduce timelines.
• It helps to compare planned and actual progress.
• It helps to make dependencies visible and clear.

How does critical path help in project management?

Critical path allows teams to identify the most important tasks in a project. ... This provides a higher level of insight into your project's timeline and a correlation between tasks, giving you more understanding about which task durations you can modify, and which must stay the same.

What is the critical path in a Gantt chart?

The critical path in the Gantt chart is the sequence of tasks that could delay the project end date when any of the tasks get delayed. When this option is enabled, your cards are constantly checked, which can impact the performance of the Gantt chart.

Is Gantt chart useful?

Gantt charts are useful for planning and scheduling projects. They help you assess how long a project should take, determine the resources needed, and plan the order in which you'll complete tasks. They're also helpful for managing the dependencies between tasks.

What is the difference between Gantt chart and critical path method?

The disadvantage of the Gantt chart is that it does not show the dependency of tasks to each other and it does not show which tasks are 'critical' to finishing the project on time. ... Like with the Gantt chart, the first step in creating a critical path diagram is to list all the activities of your project in a table.

What advantage does the CPM Pert has over the Gantt chart scheduling tools?

PERT charts are generally used before a project begins to plan and determine the duration of each task—so they don't have to show the actual dates of your project. They also do a better job of showing whether certain tasks need to be completed in order or whether they can be completed simultaneously.

What is difference between Gantt chart and PERT chart?

Essentially, a Gantt chart is a bar chart that lays out project tasks and timelines linearly. ... A PERT chart, on the other hand, is structured as a flow chart or network diagram that displays all the project tasks in separate boxes and connects them with arrows to clearly show task dependencies.

Which is the link between Gantt Chart & Pert CPM network?

PERT and Gantt charts are visualization tools that are often used in project management. Both of these charts are used for task scheduling, controlling, and administering the tasks necessary for the completion of a project.

What is the purpose of PERT chart?

A PERT chart is a visual project management tool used to map out and track the tasks and timelines. The name PERT is an acronym for Project (or Program) Evaluation and Review Technique.

Why is PERT used?

PERT is a project management planning tool used to calculate the amount of time it will take to realistically finish a project. ... PERT charts are tools used to plan tasks within a project - making it easier to schedule and coordinate team members accomplishing the work.
