How many types of work breakdown structures are there?

How many types of work breakdown structures are there?

The Project Management Institute (PMI) Project Management Book of Knowledge (PMBOK) defines the Work Breakdown Structure as a “deliverable oriented hierarchical decomposition of the work to be executed by the project team.” There are two types of WBS: 1) Deliverable-Based and 2) Phase-Based.

What should be done by a project manager to ensure that all work in the project is included?

What should a project manager do or follow to ensure clear boundaries for project completion?

• Scope verification.
• Completing a scope statement.
• Risk management plan.
• scope definition.

What are the estimation techniques?

Major project estimation techniques

• Top-down estimate.
• Bottom-up estimate.
• Expert judgment.
• Comparative or analogous estimation.
• Parametric model estimating.
• Three-point estimating.

What is 3 point estimation in project management?

Three point estimating is a technique which utilizes an optimistic and pessimistic estimate to determine the ideal estimate value for a project task. It is a shoe-in for PMP exam questions, which is not likely to change anytime soon. It allows known risks to be quantified and built in to the project budget.

What is the best way to estimate a project?

How Do You Estimate Time for a Project?

1. Break down the project into activities and then further into smaller tasks, then estimate each task.
2. Take a look at similar projects you’ve done in the past and how many hours they took.
3. Take past project timelines and adjust them for differences in the new project.

Which estimation technique is most accurate?

Bottom-up Estimating

• This is the most accurate technique and provides reliable results.
• You can use this technique when you have all the project details.
• This technique is costly and time-consuming.

What are the steps for project planning?

1. 9 steps on how to create a project plan online.
2. Step 1: Identify all stakeholders.
3. Step 2: Define roles and responsibilities.
4. Step 3: Hold a kickoff meeting.
5. Step 4: Define project scope, budget, and timeline.
6. Step 5: Set and prioritize goals.
7. Step 6: Define deliverables.
8. Step 7: Create a project schedule.

What is the major advantage of using analogous estimation technique?

Analogous estimation is a better way of estimation in the initial stages of the project when very few details are known. The technique is simple and time taken for estimation is very less. Organization’s success rate can be expected to be high since the technique is based on the organization’s past project data.

What is analogous estimating?

Analogy Cost Estimating is a technique used to estimate a cost based on historical data for an analogous system or subsystem. In this technique, a currently fielded system, similar in design and operation to the proposed system, is used as a basis for the analogy.

What is the difference between analogous and parametric estimating?

Analogous estimating uses an “analogy” – comparing a past similar project to your current project. Parametric is more accurate, specifically when the underlying data is scalable. Parametric uses a relationship between variables (a unit cost/duration and the number of units) to develop the estimate.

What is the parametric estimating technique?

Parametric estimating uses a statistical relationship between historical data and other variables (e.g., square footage in construction) to calculate an estimate for activity parameters, such as cost, budget, and duration.

What is bottom-up estimation in project management?

Bottom-up estimating involves the estimation of work at the lowest possible level of detail. These estimates are then aggregated in order to arrive at summary totals. Bottom-up estimates take more time to complete, but they also are more accurate than either analogous or parametric estimates.

What is top down estimating in project management?

Top-down estimating occurs when company management imposes a cost and/or duration on a project, usually without a detailed cost analysis. The estimating process is derived from the opinions of a group of experienced managers, possibly supplemented by outside experts.

Which is the most important in managing costs?

One of the most important elements of a project cost management tool is cost estimation, which is the practice of forecasting the price of a complete project with a defined scope. There are several types of cost estimation in project management, including fixed, variable, direct, and indirect cost estimation.

What are the advantage of top-down approach?

Benefits are realized in the early phases. You can replace many manual processes with early automation. You can implement password management for a large number of users. You do not have to develop custom adapters in the early phases.

What is the cost management?

Cost management is the process of estimating, allocating, and controlling project costs. The cost management process allows a business to predict future expenses to reduce the chances of budget overrun. As the project plan is executed, expenses are documented and tracked, so things stay within the cost management plan.

Why is cost planning important?

Cost planning is an essential part of the project management process. Project managers need to understand where costs fall in their schedule to manage demand for resources. This type of schedule is essential to cost planning, to help build up picture of planned costs over time.
