## Parametric Estimating | Definition, Examples, Uses

When you need to estimate the cost of a project or parts of a project, you almost inevitably come across the technique of parametric estimating. This is a quantitative approach to determine the expected cost based on historic or market data. It is also a method that is used in the ‘estimate cost’ process in …

## Discounted Payback Period: Definition, Formula, Example & Calculator

The discounted payback period (DPP) is a success measure of investments and projects. Although it is not explicitly mentioned in the Project Management Body of Knowledge (PMBOK) it has practical relevance in many projects as an enhanced version of the payback period (PBP). Read through for the definition and formula of the DPP, 2 examples …

## Cost of Quality (COQ) – Cost of Conformance vs. Cost of Non-Conformance

Cost of quality is a technique under the Project Quality Management Knowledge Area of the PMI framework (PMBOK®, 6th edition, ch. 8.1.2.3). The concept comprises of a short- and long-term consideration of quality expressed in its two components: cost of conformance and cost of non-conformance.

## Estimating Cost of a Project: Techniques and Examples

Estimating cost is an important process in project management as it is the basis for determining and controlling the project budget. Costs are estimated for the first time at the beginning of a project or even before a project has started. Subsequently, the (re-)estimation of the project cost is repeated on an ongoing basis to …

## What Is the Rough Order of Magnitude (ROM) and How Is It Calculated?

During the project initiation phase (or when you are preparing for a project management exam) you will likely come across the term rough order of magnitude (ROM). The PMI’s Project Management Body of Knowledge refers to the rough order of magnitude as an initial estimate in the “estimate cost” process (source: PMBOK®, 6th edition, part …

## Calculator for the Rough Order of Magnitude (ROM) Range

If you are in the initiation phase of a project or studying the PMBOK for your PMP exam you will find this ROM Range Calculator useful. This tool helps you determine the minimum and maximum values of the range of your rough order of magnitude estimate. Introduction to the ROM Calculator There are numerous estimation …

## What Is Schedule Variance (SV)? Definition, Formula, Example, Calculator

When you are in the process of controlling the schedule of your project, or when you are preparing for your PMP exam, you will likely make use of the Schedule Variance (SV) at some point. This is one of the key indicators of the variance analysis which is part of the earned value management of …

## IRR Calculator: Internal Rate of Return (IRR) of Projects

The Internal Rate of Return is one of the most common success measures of projects and investments. It is a profitability metric that can be used to assess and compare different project options even if their investment amounts, timeline and cash flow characteristics differ. In project management, it is often used for cost-benefit analyses as …

## Three-Point Estimating and PERT Distribution (Cost & Time Estimation)
