History Of Iterative

For the June 2003 IEEE Computer issue dedicated to agile processes (edited by A. Cockburn and L. Williams), Vic Basili and CraigLarman wrote history of iterative/incremental/agile lifecycle processes. You can get the PDF of the whole article from This is an excerpt from the beginning of the paper, from the 1950s-1980.

A brief history of agile methods · Intense Minimalism. There is a common misconception that agile methods are just for smaller projects.

A brief history of agile methods · Intense Minimalism

While it’s obvious the falsity of this statement to anyone that actually did it properly, it’s also obvious when we check the origins of agile. 1930s — Walter Shewhart proposes a series of short “plan-do-study-act” (PDSA) cycles.1950s — The X-15 hypersonic jet applied incremental and iterative development.1958 — Project Mercury (NASA) software development, ran with half-day iterations. “All of us, as far as I can remember, thought waterfalling of a huge project was rather stupid, or at least ignorant of the realities.” — Weinberg G.

Mile High Agile 2019 - 37 Invited, Accepted and Proposed Submissions

The good news is that the 'shouldn't be used for' list continues to go down. In fact - I'm encouraged by the trend from 'should not' to 'could' to 'absolutely should' - when it comes to applying Lean and Agile. But over that same time period, I've watched a number of organizations, populated with very smart, creative and passionate people, struggle with their own Agile journeys.

Non-verbal Exercises for Agile Retrospectives - Ben Linders

Earlier this year I attended a sessions at the Retrospective Facilitators Gathering 2016 where we explored different techniques and ideas that can be used in non-verbal exercises for Agile Retrospectives. Here’s what we came up with. Practical agile for enterprise IT. Scalable Agile Estimation and Normalization of Story Points: Introduction and Overview of the Blog Series (Part 1 of 5)The Agile Management Blog. Agile estimation topics such as relative size effort estimation in story points and velocity based on story points are well-known.

Relative size estimation done as a team effort leads to improved shared understanding of stories. It takes less time than estimating effort in time units (ideal hours or idea days). Relative size estimates in story points are more stable than estimates done in time units. Guiding Organizational Design With SOA Principles -LeadingAgile. A couple of years ago, Mike Cottmeyer wrote a blog post on How to Structure Your Agile Enterprise.

He contended at scale we need to organize teams around capabilities. He referenced refactoring legacy architecture into a Service Oriented Architecture (SOA). We have proven this with many of our clients over the last couple of years. We want to organize around products and their capabilities. A capability is an outcome-based view of what the product does.

Converting effort estimates into project durations and team sizes is an important part of project planning.

Schedule Questions: Pair Programming and the PNR Curve

How this is done varies from project manager to project manager, to some it is an art, others a science, and to many a case of living with everyday constraints. Today I will focus on the science and its implication to pair programming. If your initial project estimates indicate 72 person months of effort how do you best resource it? 1 person for 72 months? 72 people for 1 month? Intuitively we know that 1 person for 72 months might work (providing they had all the right skills) but typically business wants the benefits of a project as soon as possible. 72 people for 1 month is extremely unlikely to work, unless the project is simple and massively parallel, like cleaning oil off rocks on a beach. While adding team members to a project increases costs in a linear fashion, the project timeline is not reduced in a corresponding linear way.

LeadingAnswers: Leadership and Agile Project Management Blog

As work switches from industrial work to knowledge work, companies face a perfect storm of employee engagement and retention issues. On the one hand the time taken to learn a job is increasing as domains become more complex and new tools add layers of abstraction and integration problems. On the other hand the average time spent in a job is decreasing. Alleman EV Agile Success%20(V3) 14 Obstacles to Agile in Government. Why Scrum Doesn’t Work in the Enterprise. June 10, 2014 | Author: PM Hut | Filed under: SCRUM Why Scrum Doesn’t Work in the Enterprise By Curtis Guilbot Stop me if you’ve heard this one before: A couple of Fortune 50 clients I worked with had recently spent a few million on training their development staff in “enterprise scrum” with a well-known author/trainer in the field.

Why Scrum Doesn’t Work in the Enterprise

There were posters everywhere, town hall meetings (which were expensive all-day affairs, since this was a global company), a gung-ho spirit among many department managers. #NoEstimates? Get a grip. Sprint level estimations are vital. The purist in me loves the concept of no estimates.

#NoEstimates? Get a grip. Sprint level estimations are vital

Imagine a world where designers could just design until everything looked perfect, developers could just code until everything worked exactly the way they wanted and at the end of it all, whenever that might be, their labour of love is packaged and delivered to the happily waiting customer. Let’s all take a moment to get realistic. The whole elitist, self righteous attitude towards the entire #NoEstimates movement needs to stop. Lean Agile in Construction Projects - 9/11/11 - 10 Years Later. I spent 2 fulfilling hours watching Discovery Channel‘s show on building the new Tower 1 of the World Trade Center called “Rising.” The commercial free special was especially poignant because of the many stories of individuals effected by the 9/11/2011 twin towers falling, and their calling to help re-build Ground Zero.

“The whole world is looking at us and our response to the tragedy.” Essentially, the story revolved around the contruction of Tower 1 and the goal of building it up to 1000 feet before 9/11/2011 (1776 feet at completion in 2013). Rocket to Mars: A Sprint Planning Game. “Many team and their product owners believe that the team's unique job is to deliver more and more story points, but we consider this to be a complete misunderstanding of the relation between the team and the product owner” said Damien Thouvenin and Pierrick Revol. At the XP Days Benelux 2013 conference, Damien and Pierrick facilitated a sprint planning game for teams and product owners to learn about deciding to invest their sprint time to produce stories, investigate issues, reduce technical debt, or do training. Initially team members are only skilled to do one activity, by doing training they can develop new skills. When team members have these skills they are able to do different activities and the team will become more multidisciplined and capable to do more work in an iteration.

Damian and Pierrick asked the teams what they have learned from playing the game. One team explained how they were hampered by illness, which caused their velocity to go down. Things Software. Simon's Estimating Course. The Workshops on Spacecraft Flight Software. No Estimates! Well, Maybe… A passionate debate about the value of estimates has erupted in the Agile community. Running under the hashtag #noestimates, advocates of ditching estimates and estimating on Agile teams argue that the estimates serve no discernible purpose other than to add overhead to the work of developing product. Even worse, they argue that estimates are overtly damaging to teams, teamwork, performance, and value delivery. Estimates become a weapon in the hands of management, which demands that teams adhere strictly to their estimates regardless of changing circumstances, new knowledge, etc.

One thing that I advocate since at least 2008 is the idea of project management and markets in general through the models of Complex Adaptive Systems, Chaos Theory and Evolutionary Biology. I've been largely influenced by the ideas of Nassim Nicholas Taleb and his magnum opus "The Black Swan". It's an incredible idea that the markets are not bound by linear paths, but by chaotic agents that influence a complex system.

All companies are managed to deal with averages, with limited sigmas as margins of operational error. But once something big, a "Black Swan", such as the 2008 economic crisis arrives, most are not prepared to deal with it, no models are able to predict it, and the whole system shuts down and collapse. If you're unfamiliar with the idea, Google it for a moment and you will understand that companies, markets and people relationships in general, are dynamic systems that conform to evolutionary biology rules. The same applies to companies. This brings us back to CONTEXT. Connecting it and business value. Why Agile is So Hard. Search the SEI Digital Library: agile. Cyber Security and Information Systems Information Analysis Center.

There are four parts to our discussion of Agile at scale. First, we set the context by providing an answer to the question, “Why is AAS challenging?” The ten AAS primary technical best practices follow. We then briefly address how an organization can prepare for and achieve effective results from these best practices. We conclude with a listing of selected resources to help you learn more. Also, we’ve added links to various sources to help amplify a point—be mindful that such sources may occasionally include material that might differ from some of the recommendations below.

Every organization is different; judgment is required to implement these practices in a way that provides benefit to your organization. These practices are certainly not complete—they are a work in progress. Agile Architecture Applied - Neotys Testing Roundup. CCRP - Command and Control Research Program.
