3-point estimates. good for you!

Musings on Project Management

Here's my three point estimate paradox: We all know we must estimate with three points (numbers). so we do it, reluctantly None of us actually want to work with (do arithmetic with) the three points we estimate. In a word, three point estimates suck -- not convenient, thus often put aside even if estimated -- and most of all: who among us can do arithmetic with three point estimates? But Monte Carlo Risk Management Statistics

Musings on Project Management

We all make estimates; and we all make estimates all the time. When I make the 20 mile trip each Tuesday to a client site, I estimate adjustments to a baseline based on weather and road construction and if I know about an accident. Really, no one sets out to do anything meaningful without some estimate in mind re time, or cost, or risk; usually we can also notionally estimate the scope. So, agile estimate

How to Evaluate Risk Velocity

Project Risk Coach

Ask a PM: How to Get Proper Estimates

Evaluating Project Schedules Utilizing Quantitative Risk Analysis

Often times, risks occur and project managers lack adequate schedule reserves. If a project is estimated at 120 days, the project manager may add a 10% pad, an additional 12 days. The project manager estimates the project duration to be 132 days. Analyzing the Highest Risks.

Estimating the Risk

Herding Cats

Risk is everywhere on projects. This risk comes from two types of uncertainty. The idea of risk and its management and handling is a critical success factor for all software development. One of the most rigorous theorems of economics [1] proves that the existing means of production yields greater economic performance only through greater uncertainty that is, through greater risk. Without these estimates, there is no risk management. NoEstimates Risk

Risk Management is one of the well established fundamentals of Project Management. Whatever system or tool you use, the basics of rating risks with some degree of severity and impact is well understood, and then doing something to stop it (because they usually are threats).

Estimates, Forecasts, Projections

Herding Cats

Estimates. An Estimate is a value inferred for a population of values based on data collected from a sample of data from that population. The estimate can also be produced parametrically or through a simulation (Monte Carlo is common, but Method of Moments is another we use). . Estimates can be about the past, present, or future. We can estimate the number of clams in the Pleistocene era that are in the shale formations near our house. Estimate to Complete.

Uncertainty creates Risk, Decisions in Presence of Uncertainty Requires Estimating

Herding Cats

According to ISO 31000, a risk is the effect of uncertainty on objectives and an effect is a positive or negative deviation from what is expected. Every step has an element of risk that needs to be managed and every outcome is uncertainty. In the context of risk management, uncertainty exists whenever the knowledge or understanding of an event, consequence, or likelihood is inadequate or incomplete. Let's define what an estimate is. IT Risk Management.

Decisions Without Estimates?

Can you make a decision without an estimate? There are NO means of making a credible decision in the presence of uncertainty without estimating the outcome of that decision. Don't assume, Estimate. This process is the basis of all risk management. IT Risk Management.
