How To Be An Estimating Superhero

Girl's Guide to PM

A statistical model for estimating isn’t normally something I’d put in the ‘make my job easy’ box, but I might just have found one that works. What if you want an estimate that is, say, 75% reliable? PERT can’t give you those kinds of estimates. How reliable is this estimate?”.

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.

No more initial estimates? NOOOOOOOOOOO!

Kiron Bondale

You are assigned to manage a project and before you or your team have had an opportunity to start to chip away at the looming mountain of uncertainty, you get put on the spot to provide a cost or schedule estimate by your project sponsor or some other stakeholder.

Estimating Resources

There's a never-ending opportunity to learn how to estimate in the presence of uncertainty. When you hear that estimates are a waste (we'd rather be coding), estimates are fiction, we're bad at estimating, and the plethora of other excuses for not learning how to estimate, ask if that person has done the minimal homework to learn how to estimate needed to make decisions in the presence of uncertainty found on all software development projects. .

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. 2 (2016), pp.

Why Johnny Can't Estimate?

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. To be informed how to estimate in this broad range of domains, problems, and impacts - education, exp[erience, and skill are needed. Gow to avoid common estimating mistakes.

Estimate everything?

Musings on Project Management

Mike Cohn on estimating (from his email blasts): "Because I've written a book on estimating, people seem to think I estimate everything on my product backlog. I ask a team to estimate a product backlog item only when having the estimate will lead to actionably different behavior. So, for example, I might ask a team for an estimate on a user story so that I can decide if I want. agile estimate

Why We Need Estimates

The ability to generate reliable cost and schedule estimates is a critical success factor necessary to support business projects. Why Guessing is not Estimating and Estimating is not Guessing.

Quick Summary of Estimating Advice

Herding Cats

We can't estimate things we've never done before - this is simply not true. If you truley haven't done the work before, you're probabiliy not the right person to be estimating for those wanting to pay you. . Estimates are guesses, because we don't know that the future is - this is a fundamental misunderstanding (either with intent or omission) on how estimates are made. We've never done this before, so how can we possibly estimate how long it will take?

Why Ranged Estimates Are More Effective Than Single Point Estimates


This is why making ranged estimates for your projects is more realistic and reliable than aiming for a singular deadline. We use ranged estimates all the time in daily life. The advantage of making ranged estimates. Ranged vs single-point estimates.

What would be the evidence that we could make decisions in the presence of uncertanty without estimating the impacts and outcomes of those decisions? . The Myths of No Estimates and the busting of them is one purpose of this blog post. Before we start, let's look with the notion of estimation.

Estimating on Non-Trivial Software Projects

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. I have an 80% confidence (an estimate) I can deliver what you need on or before September 15 (an estimate), at or below $15,000.oo (an estimate) with a 15% error band (an estimate). .

And, as these things go, it has a lot of humor, but also a lot of wit.

Common Ground for a Conversation about Estimating

Herding Cats

Neil Killick posted a good question, what's the common ground for talking about estimates. All estimates have two attributes - accuracy and precision. The values of these two attributes are what those needing the estimates are after. With the knowledge of the two values of these two attributes the decision makers can assess the "value" of the estimate. That request comes from those asking for the estimate. But that dysfunction is not "caused" by the estimate.

Estimating is an Everyday Life and Everyday Projects

A recent twitter post started out with I predict my train will depart from platform 12 in 10 minutes: degree of predictability correlates with length of time I then asked and what is the evidence on which you base this estimated time of departure? I got back I didn't estimate departure, there is a timetable there, but Trains someone's run late & platform sometimes changes. But in fact - mathematical fact - there was an estimate made.

Book of the Month - IT Project Estimation: A Practical Guide to the Costing of Software

Estimating is part of all decision making in the presence of uncertainty. Accuracy and precision are two primary attributes of all estimates. We all know estimates are hard. So why is estimating a topic that seems to be the whipping boy for software developers these days?

The Pseudo Science of No Estimates

Herding Cats

estimates are the smell of dysfunction, so let's not estimate and the dysfunction will disappear." Because "we're just developers who can't even make high level estimates how much it will cost and we work for bonehead managers who can't tell the difference between a good estimate and a bad estimate," doesn't have the same ring. This comes to the discussion of Value at Risk and what are estimates for other than to protect Value at Risk.

Visualise Estimated Time vs Actual Time spent on Tasks


You can now easily view task estimates, actual duration and remaining hours left on your tasks so you can easily analyze your project’s progress at a glance. When you add a new task to your project, you can include the estimated amount of time it will take to finish the task.

Forecasting versus Estimating - are they Different or are they the Same

One of the escape clauses of #Noestimates is to re-label Forecasting as NOT Estimating , It is forecasting, based on empirical data. This is in comparison for estimating purpose for a theoretical model that produces data, parametric from empirical or theoretical models that produce data.

Can You Make a Decision in Presence of Uncertainty Without Estimating?

They started with “Estimates are a waste, stop doing them.” Those advocates also started with the notion that estimates are a waste for the developers. The size of the “value at risk” is also the starting point for estimates. If the project is small (de minimis) meaning if we over run significantly no one cares, then estimating is likely a waste as well. Next comes an original post from Woody – “you can make decisions with No Estimates.”

Advice for Project Managers: Stepping in to Manage an Ongoing Project and Promoting Ranged Estimates


For the last year we’ve been using ranged estimates to build out our schedules. How do we convince them to go with a two-point estimate? Dear Reality: Ranged estimates are awesome, so I’m totally with you on that one. I would start a campaign of education: Talk to your customers about why two-point estimates are actually a more mature and realistic way of scheduling and why that should give them more confidence.

This approach makes it look like the voter turnout is dramatically different between 2008 and 2016. Each dot (diamond and triangle) needs a confidence band from the original estimating process. Was that estimate an 80% confidence estimate, a 60% confidence estimate, a wild ass guess.
