Beware false accuracy with quantitative risk assessment

Kiron Bondale

If you view an advertisement touting multiple benefits of a product with which you’ve had no previous personal experience and are later asked about the risks associated with its use, you are likely to state that it is less risky even though there is no connection between its benefits and risks.

There are two reasons why Project Estimation is a big deal for project managers. And second, poor estimates are often a primary reason for a project cost or schedule over-run. So, in this article, we’ll take a careful look at project estimation, to help you learn how to master the art and craft of doing it well. What is Project Estimation? Why is Project Estimation so hard? The Estimation Knife Edge. Methods and Tools for Project Estimation.

Project Estimation Techniques Everyone Needs To Know

Project estimation techniques help project managers accurately estimate essential elements, such as cost and scope , within their projects. What are project estimation techniques? An estimate is a rough calculation of something. Why are project estimates important?

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.

Software Estimating Resources

Herding Cats

This blog page is dedicated to the resources used to estimate software-intensive systems using traditional and agile development methods. The reason for this resource page is the lack of understanding of how to estimate, the urban myths about software estimating, and the fallacies that estimating is not needed, when developing software, in the presence of uncertainty, when spending other peoples money. Estimating Probable System Cost,” Stephen A.

RBS is one more technique for your estimation tool belt!

Project managers need to be comfortable with different estimation techniques. Foundational project management courses will teach you about analogous, bottom-up, parametric and three-point estimating. Take a course covering agile delivery and you’ll learn about relative sizing techniques such as estimating poker or t-shirt sizing. Estimate the size or effort of that story or work package.

Why Johnny Can't Estimate?

Risk Management is How Adults Manage Projects - Tim Lister. Since all risk comes from uncertainty - reducible (Epistemic) and irreducible (Aleatory), estimating is a foundation of all we do. There is no discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately. This includes planning for and execution the project by phase and activity level cost estimates.

Analogous Estimation Vs Parametric Estimation

iZenBridge

As a Project Manager, doing project ESTIMATION is a key responsibility but how often are we able to deliver the project under budgeted cost and time? What will help in this scenario would be the right understanding of estimation tools and techniques. There are many techniques for project estimation like Bottom-Up Estimation, Parametric Estimation and Analogous Estimation. To start with, let’s understand Analogous Estimation, what exactly does it mean?

Principles of Cost and Schedule Estimating

Herding Cats

One of the 4 summary root causes of project performance failures is Unrealistic Cost and Schedule Estimates based on inadequate risk-adjusted growth models. Those making these claims may have their own personal purposes, their own agenda, their own reasons for sell this idea that estimates are somehow no longer needed when we're spending other people's money to produce value in exchange for that money. If you have no uncertainty, then estimates provide no value.

Estimating is a Learned Skill

Herding Cats

Estimating is a learned skill, used for any purpose from every-day life to management of projects. When I left for the airport this morning to catch my flight to a customer site I estimated, given the conditions, how much time I need to get to my favorite parking spot at DIA. The same process for estimating is applied to multi-billion dollar projects we work. Here's some materials that provide the tools and processes needed to learn how to estimate.

Reasons to Estimate and Measure

Herding Cats

Estimating Software-Intensive Systems: Project, Products, and Processes , Richard D. Stutzke is a starting point for estimating software projects. I recommend it for anyone starting out in the estimating business all the way to seasoned veterans. Any estimating process requires discipline and repeatability to produce accurate and precise results. The estimate can also be produced parametrically, empirically, or through a modeling and simulation.

Risk Management is How Adults Manage Projects

In a recent exchange in social media, it was clear the notion of risk and the sources of risk, the consequences or risks and managing in the presence of risk was in very unclear, when it was conjectured , we can simply slice the work into small bits and REDUCE risk. . First, the only risk that can be reduced is the risk created by Epistemic Uncertainty. Making things small does not reduce the risk it may make the uncertainty smaller.

Small Batch Sizes are NOT Risk Management

Herding Cats

There is a popular fallacy in the Agile community that small batch sizes are Risk Management. What small batches do is provide information that informs risk management at a fast rate. This approach is a closed loop control system, where the estimates work (in your choice of ordinal units) is the starting point. As the work progresses the TO DO value goes from the original estimate to the new estimate to complete. We Handle risks" in a variety of ways.

A nice conversation on twitter about estimates on software brought up the topic of estimates as commitments. The #NoEstimates advocates see estimates as making commitments. Yes, commitments are made when we estimate. Just for the reference, . Just for the reference, a commitment is the state or quality of being dedicated to a cause, activity, etc. But that's got NOTHING to do with the need for the estimate and EVERYTHING to do with bad management.

4 Fallacious Reasons to Estimate and Why Those Are Fallacious

Risk, Their Sources, and Handling Strategies

Herding Cats

Risk identification during early design phases of complex systems is commonly implemented but often fails to identify events and circumstances that challenge program performance. Inefficiencies in cost and schedule estimates are usually held accountable for cost and schedule overruns, but the true root cause is often the realization of programmatic risks. This is sometimes labeled an Unknowable Risk. Separating Aleatory and Epistemic Uncertainty for Risk Management .

One of the more subtle changes in the Sixth Edition of the PMBOK Guide is the elimination of all references to Critical Chain Method (CCM). I was unable to convince team members to provide such aggressive estimates given the organization’s prevailing culture. Given that a fair bit of padding remained in each activity duration estimate, the buffers ended up being bloated and milestone dates were later than would have been previously planned.
