This episode is part of a wider mini-series looking at Estimation in Software Development.

In last week's episode, I looked at a number of methods that fall under the Qualitative approach to software estimation.

Qualitative estimation is predominantly based on expert judgment, something based on subjective thought process.

In this episode I wanted to take a specific look at another method I personally consider a qualitative approach

But it's so different to those discussed in the last episode, I felt it needed its own, the #NoEstimate approach

#203: Estimation - Is Artificial Intelligence the answer? 15:23

15:23

This episode is part of a wider mini-series looking at Estimation in Software Development. In this episode, I ask the question, is AI the answer? Following on from the episodes on Qualitative and Quantitative approaches, it's easy to see there are pros and cons to individual practices. And realistically, it feels like you will need a blend of various approaches to create truly valuable estimates. But, this all seems like a lot of work and investment, a lot of training, tools and time to achieve. And even more so to iteratively improve to nudge towards those valuable estimates. As I'll say many times in this series, producing estimates costs. Producing valuable estimates costs a lot. Thus, it doesn't take much of a leap of logic to ask the question, can AI help us here? In an ideal world, there would be an AI-powered tool that would just do the work for us. Thus, I explore how such a tool could come into being, and probably more importantly, why I doubt it will happen any time soon. ----- Find this episodes show notes at: https://red-folder.com/podcasts/203 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In the last couple of episodes, I've looked at a number of methods that fall under the Qualitative approach to software estimation. Qualitative estimation is predominantly based on expert judgment, some think based on subjective thought process. In this week's episode, I want to move on to discuss some Quantitative estimation approaches. While Qualitative estimation is predominantly based on expert judgement, Quantitative is based on something we can count or calculate, a use of statistical analysis based on historical data. In this episode, I specifically want to discuss two quantitative techniques - Monte Carlo simulations and Statistical PERT (or SPERT for short). ----- Find this episodes show notes at: https://red-folder.com/podcasts/202 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In this episode, I wanted to highlight the emotional baggage that you developers may associate with estimation, and through no fault of your own, will carry that baggage into future estimation work. In the episode, I look at the psychological scarring left behind from decades of using estimates as punitive targets. Like most experienced developers, I've worked in organisations that turn estimates into punitive targets - where a well-meaning estimate has been turned into a commitment, and ultimately, a stick to beat the team with. Now that stick has ranged from the aggressive to the passive, be it threats of dismissal or simply discussing the failure to hit the estimate. ----- Find this episodes show notes at: https://red-folder.com/podcasts/198 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In this episode, I wanted to look at the impact that dependencies have on software estimation. This episode was inspired by a blog post on scrum.org entitled "Eliminate Dependencies, Don't Manage Them", which I read while preparing this series. In brief, the article talks about how you're better off eliminating dependencies rather than trying to manage them through normal traditional management processes. In his book, Software Estimation, Demystifying the Black Art, Steve McConnell says that size of the software is the single most significant contributor to project effort and schedule. Personally, I'd like to suggest that dependencies, if not of similar importance, are a close second. ----- Find this episodes show notes at: https://red-folder.com/podcasts/197 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In this episode, I want to encourage you to mentally separate estimation and planning. They are often conflated, which leads to confusion, distrust and dysfunctional behavior. An estimate is generally part of a plan, and a plan can be the outcome of the act of planning. Software development can't be delivered without planning, even if it's only the most cursory of activities. Software development can be delivered without an estimate. ----- Find this episodes show notes at: https://red-folder.com/podcasts/196 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In last week's episode, I asked you to think about what the term "estimate" means to you, your team and your organisation. In the episode I talked about different definitions that could easily be conflated - the amount of effort, a target, and a commitment. In this week's episode I want to continue the discussion by looking at estimates "proxies" - what they are, why they can be useful and how to avoid the trap of confusing them for scheduling. ----- Find this episodes show notes at: https://red-folder.com/podcasts/195 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In this week's episode, I want to discuss what the term "estimate" may mean to you and the colleagues that you work with. The term 'estimate' is often used interchangeably to mean the effort required, the target completion date, or even a commitment to complete the work by a specific date. Often the meaning of an "estimate" changes between people within even a single team, let alone a organisations - thus it is often a cause of friction and dysfunction due to it being in "the eye of the beholder". ----- Find this episodes show notes at: https://red-folder.com/podcasts/194 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

This episode is part of a wider mini-series looking at Estimation in Software Development. In the last episode, I talk about the short hand of a "valuable estimate" - an estimate that is desirable for the organisation asking for it. While what constitutes "valuable" will differ from organisations to organisation, team to team, and maybe even piece of work to piece of work, I feel that it will mostly be related to acceptable level of accuracy and precision. Accuracy is how close to the actual the estimate was - which realistically can only be assessed after the work - and precision is how broad a range is acceptable - which can be defined as part of providing the estimate - and if anything also indicates confidence in the estimate - a narrower range indicating a higher confidence, a wider range indicating a lower confidence. In this episode I wanted to talk about how Predictability is part of this conversation ----- Find this episodes show notes at: https://red-folder.com/podcasts/192 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

14:23

This episode is part of a wider mini-series looking at Estimation in Software Development. So for this episode I want to introduce the idea of a "valuable estimate" and what that may mean for you. As I go through this series I will use the term "valuable estimate" as a short hand for some value that is desirable by the organisation asking for it. This may seem a little vague … and to be honest, by design it is. I've spent a lot of time trying to decide what the best estimates should look like - but ultimately I feel it depends on a variety of factors - and is likely to be specific to an organisations - or maybe an initiative - or maybe even to an individual piece of work. We quickly find ourselves in the consultants stock answer of "it depends". So while, in this episode I'll discuss to key characteristics that I believe affect the value of an estimate, the actual (or imagined) value of an estimate will be in the "eye of the beholder". Thus the short hand of "valuable estimate" ----- Find this episodes show notes at: https://red-folder.com/podcasts/191 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

18:24

I started the mini-series in episode 189 by providing the following guidelines: Don't invest in estimates unless there are clear demonstrable value in having them Agree what a "valuable" estimate looks like - this will likely be a desirable level of accuracy and precision for an estimate Provide the team with training & time to develop their estimation skills Collect data on points 1-3 and regularly review if you have the balance correct In this episode we dive into "Don't invest in estimates unless there are clear demonstrable value in having them" Estimates are not free – and I would argue that truly valuable estimates are often prohibitively expensive to produce. Thus in this episode, I ask the question are you getting the ROI on that investment. And more importantly – can you prove that. ----- Find this episodes show notes at: https://red-folder.com/podcasts/190 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

#189: Estimation - a review 21:12

21:12

Back in January 2023, in episode #160, "Revisiting Software Development Estimation," I made the commitment to revisit and potentially revise my views on software development estimation. While I acknowledged the desirability of estimations for reasons like cost, risk, and planning, the episode recognized that these desires don't always make estimations attainable or accurate, particularly in complex or complicated domains like software development. In 2023, I planned to research estimation techniques, focusing on their feasibility and implications in the software development process. This research would involve exploring resources such as online courses, books, and audience suggestions, with the intention of sharing findings later in the year. This is the first, if somewhat delayed, in a series of episodes following that work. In this episode I will provide a summary of upcoming episodes and how they fit together. ----- Find this episodes show notes at: https://red-folder.com/podcasts/189 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

Following on from the last two episodes that look at the dysfunctional and unexpected results that can from the seemly well intentioned call for "more planning", this week's episode takes a look at a similar paradox - the call for "more developers". We look at why "more developers" does not generally equal "greater output" - the unexpected operational overheads that a larger team generate. We look at some circumstances, when used with caution, increasing the headcount can be the right thing. And we look at suggestion for improving productivity without increase numbers. ----- Find this episodes show notes at: https://red-folder.com/podcasts/188 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…

I began by defining small batch sizes - the breaking of work down into more manageable tasks, which can improve the speed and quality of your output. I then explore how small batch sizes play a pivotal role in transaction-based costing, promoting efficiency and cost-effectiveness by enabling more precise tracking and control of costs. I also examine the benefits that come with this combination - enhanced agility for software changes, better predictability for improved financial forecasting, enhanced transparency for granular insights into cost allocations, and streamlined processes for reducing waste and improving value delivery. And to wrap up, I talk about some the challenges of a transition from traditional methods and implementing small batch sizes. ----- Find this episodes show notes at: https://red-folder.com/podcasts/177 Have an idea for an episode topic, or want to see what is coming up: https://red-folder.com/podcasts/roadmap…
