A metaphor in agile development of building a transportation device in the picture below. The logic goes like this: In the end I want a Panel Van to deliver groceries for my door-to-door organics company. I want vehicle for a... Continue reading

In a CrossTalk article Risk Management for Dummies, Tom DeMarco speaks about late software projects and the approaches for the solution. The notion of early start as the solution for late finish needs to address the core question, but fails... Continue reading

When I hear "we suck at estimating," or "we can't make good estimates, because people take them as commitments," I wonder what would be the answer if those statements were restated as... "We suck at designing good database schemas." "I... Continue reading

Risk Management is about many things - but it is first and foremost about estimating future outcomes. Suppose one of you wants to build a tower. Will he not first sit down and estimate the cost to see if he... Continue reading

Plans are critical, a schedule to implement that plan comes next. With the Plan, the sequence of the work is needed to assure the value to the customer is delivered in the proper order. That order is an order because... Continue reading

Many times I hear about Cost of Delay, Deliver Value, Measure story points, or Measure Stories. And a myriad of other assessments of project performance, all of which - OK, most of which are examples of Open Loop Control. Back... Continue reading

In project work we're looking to create or change something, in some defined period of time, for a defined cost. This means we're going to spend money now for some future outcome. The elements that go into this effort to... Continue reading

When we hear descriptons of Dilbert style management, with posting and reposting Dilbert cartons showing pointy haired bosses Doing Stupid Things on Purpose and no actionable advice on how to take corrective actions - then you know for sure the... Continue reading

The use of Bayesian Statistics in project work is well developed. Here's an example of the approach. The drivers for each uncertainty can be modeled to produce on estimate of the risk of the project not producing the desired outcomes.... Continue reading

When I hear what are the odds of success for a project, it tells me there is an undertstanding gap in how statistical processes are used in projects to produce probabilistic estimates of three things: The probability of completing on... Continue reading

Qualitative risk analysis includes methods for prioritizing the identified risks for further action, such as risk response. The project members must revisit qualitative risk analysis during the project’s lifecycle. When the team repeats qualitative analysis for individual risks, trends may... Continue reading

Planning for an uncertain future calls for a shift in information management — from single numbers to probability distributions — in order to correct the "flaw of averages." This, in turn, gives rise to the prospect of a Chief Probability... Continue reading

For any model, you'll need to create a mechanism for the underlying statistical processes of the "variable of interest." In this case the probability that a hacker will appear. That data may be available outside in a database. But as well a model for that actual vulnerability. There are tools we use to assess those by looking at all the access points and other external facing systems.. With that information - and I know that's hard to come by - a probability distribution function can be generated from which you can sample data and performance analysis. Google "modeling security of software systems" as a start. I'll ask our cyber team what the tool is they use for assessing external threats.

Decision theory is concerned with the problem of making decisions. Statistical decision theory is decision making in the presence of statistical knowledge, by understanding some of the uncertainties involved in the problem. Decision theory deals with the situations where decisions... Continue reading

There is a popular notion - and a fundamentally false one - that we can't estimate, forecast, or plan something we haven't done before. Research supports the hypothesis that there are universal principles of creativity that are the basis for... Continue reading
