This is a common lament in the #Noestimates community We've never done this before, so how can we possibly estimate how long it will take? Well the first question is has it actually never been done before, or is the... Continue reading

Thanks for the link. I changed the title to be less obtuse and added a link to your post. This all comes back to developers assuming it's there money and they can try out any cockamamie ideas they like. The next big topic which was discussed in detail at the NDIA (National Defense Industry Association) meeting this week in Orlando is how to status a project using Agile on a government procurement program. Along with that the Director of PARCA (Performance Assessment and Root Cause Analyses) stated clearly that Agile will cost more money. There is huge benefit, but the produced software that is replaced when new requirements come in must be written off as a loss. Unless of course there is 100% reuse of the software that is being replaced. That's another Dark Secret of agile.

A recent Blog post used an example of negotiated estimates between the developers and management. In the example buying a car is used and compared to negotiated the cost of software development. The car was an example of knowing information... Continue reading

The notion of a balanced discussion of the topic of Not estimating work on agile projects has yet to produce any principles on which this can occur. The #NoEstimates advocates have not provided the principles by which a decision about... Continue reading

Estimating in the presence of uncertainty is a critical success factor for all project work. Uncertainty prevails on all projects, no matter the domain, development process, or governance method. Uncertainty from underlying statistical variances. Uncertainty from probabilistic events. Here's an... Continue reading

It is pure beauty. Just finished Vulcan a book about the the applicable of GR to the perihelion of Mercury. An easy read, not math, but a nice exposition of the thought processes of how mass and space are connected. My Gravitation, Missner, Thorne, and Wheller is sitting on the shelf from Grad school days. I can't do the math anymore, so need books will simple equations.

Todd, The question that needs an answer is "why do the estimates shown in the charts above different from the planned estimates?" If it is assumed the straight is "Plan" and the samples are "actuals" then what's the Root Cause of the unfavorable variances. The is core Six Sigma Closed Loop management control. If you're interested there is a paper in the current issue of "Journal of Cost Analysis and Parametrics, by Christian Smart on the issues with realism in estimate. This paper is marked "Not subject to US Copyright," so I can send you a copy. The "estimating problem" is universal. We work sometimes as a support contractor with on "Essential Views" that seek to find the root causes and provide corrective actions to cost, schedule, and performance shortfalls on programs. Without a root cause, corrective actions needed to keep the program inside the variance bands will be difficult at best.

Any effectively generated theory capable of expressing elementary arithmetic cannot be both consistent and complete. On particular, for any consistent, effectively generated formal theory that proves certain basic arithmetic truths, there is an arithmetical statement that is true, but not... Continue reading
