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.

Basis of Estimating Software Development

Herding Cats

The estimating of software development is both straightforward and complex. When it is suggested that estimating is hard, of no value, and unnecessary, always ask what principle is used to support that claim? Here are some resources that will provide guidance to produce credible software development estimates, in both traditional and agile domains. Software Sizing and Estimating: Mk II FPA , Charles Symons, John Wiley & Sons, 1991.

Risk Management is How Adults Manage Projects

Herding Cats

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. .

Tips and Tricks for Smart Project Planning

Thus, the formal critical path for small projects is often obvious enough for project managers and for project management software. Project management tools are helpful in the visualization of the schedule, and in quick calculation of an approximate end date when there are estimates in place.

Risk Management is essential for development and production programs. Risk issues that can be identified early in the program, which will potentially impact the program later, termed Known Unknowns and can be alleviated with good risk management. requires making estimates) ?

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. Johnson, STC 2010.

Misunderstanding Making Decisions in the Presence of Uncertainty

Herding Cats

What happens if you shift focus from "accurate estimation" to "reliably shipping by a date"? . If your project has no uncertainty, there is no need to estimate. The risk is created when we have not accounted for this natural variances in our management plan for the project.

One of the #Noestimates advocates has now discovered a phrase: Estimates are non-ergodic. The term “Black Swan event” has been part of the risk management lexicon since its coinage in 2007 by Nassim Taleb in his eponymous book titled The Black Swan: The Impact of the Highly Improbable.

One chapter on the Principles of Risk Management and the second chapter on the Practices of Risk Management. Since reducible and irreducible uncertainties create risk, those uncertainties need to be reduced as the project proceeds for the probability of project success to increase.

Resources for Cone of Uncertainty

The planned uncertainty not only needs to decrease over time passing, but this reduction diminishes any impacts of risk on the decision-making processes. Some feel that the cone does not provide any value for the work they do and does not match the reducing uncertainty in their estimates.

Estimation is part of project management. . The most important estimates for the project manager are related to time and cost. . Since it is easier to estimate small tasks, these estimates are often calculated and performed as point estimates, for example, a task will take 3 days.

LiquidPlanner: A Microsoft Project Alternative

LiquidPlanner

Which makes sense—after all, Microsoft Project was the go-to project management software for years. We built LiquidPlanner based on the belief that teams work best when they organize tasks by priority, make best/worst case estimates, collaborate in one central location, and can rely on a scheduling engine that automatically updates whenever plan items change. Estimating effort: LiquidPlanner manages uncertainty by using ranged estimations based on best case/worst case scenarios.

Deconstructing The Cone of Uncertainty

Herding Cats

The paper on the Cone of Uncertainty is used by many in the No Estimates community as an example of why estimates are of little use. In this paper, there is data that does not follow the Cone of Uncertainty, in that the uncertainty of the estimates does not reduce as the project proceeds. Shipping on time, to specifications, and within budget might be meaningless if a competitor is shipping software that has a greater value to the market.
