New Article: Function Point Sampling Holds Promise for Software Metrics

Cone of Uncertainty

As we embark on 2017, which is also the 30th anniversary of IFPUG Bylaws, there are reports that the software development industry is making progress. The 2015 Standish Group CHAOS report cited that agile projects are, on average, three times more likely to be successful than waterfall projects (based on their survey of over 10,000 projects.) The not-so-good news, however, is that the percent of successful projects (defined as on-time, on-budget, and with a satisfactory result) hasn’t changed much since the first CHAOS report in 1996, and hovers around 40%. The top three success factors in the 2015 report were not technical: 1. Executive Support, 2. Emotional Maturity and 3. User Involvement (agile processes ranked #7.) The need for software sizing measures to support project estimating remains just as critical as it was 30 years ago, yet IFPUG function points are not used as extensively as they could be to support software sizing. Rather than “throwing the baby out with the bathwater,” so to speak, or creating new metrics to solve old problems, Carol Dekkers and Joe Madden suggest a new way to repurpose function points to achieve estimating successes today. This article was originally published in IFPUG's Metric Views.

New Article: How Everyone Can Plan for 2017

2017 IT Budgeting

No one got into software development to budget. Developers love to code and create. If they wanted to create budgets, they’d have become accountants. Still, creating a development plan for 2017 is essential and will inevitably require budgeting and estimating, a process that should be done in partnership with business teams. This will ensure the creation of software that cost-effectively meets their needs. In this article, originally published on SD Times, Doug Putnam identifies three strategies for better budgeting and planning in the new year.

New Article: Common Ground Through PPM

Project Portfolio Planning

The most effective project portfolio planning brings IT managers and business leaders together to prioritize, scope and staff initiatives as a single team with common goals. In doing so, the process fosters better working relationships — and provides a roadmap for delivering value to the organization. In this article for Projects at Work, Larry Putnam, Jr. outlines best practices on how to determine the maximum capabilities that can be delivered within the confines of budgets, resources, and time.

AI and Automation Make Software Reliability More Important Than Ever

AI and Automation Software Reliability

If you were thinking about purchasing a driverless car, and the salesperson told you that there’s a “slight” chance that the car will fail during transit, would you still feel comfortable laying down your money? Or, if you faced an emergency, would you trust an automated robot to perform open-heart surgery, rather than the hands of a skilled physician?

While these questions might seem like the stuff of a science fiction novel, they’re quickly becoming a part of our normal, everyday world. We’re hearing a great deal about artificial intelligence and how it is replacing tasks that were once done by humans. AI is powered by software, and that software is becoming increasingly vital to our lives. This makes ensuring its reliability more important than ever.

But here’s a sobering thought: right now, IT operations teams are building software that is, on average, 95% reliable out the door. That’s right; today, a 5% unreliability gap is considered “good enough.”

How Can We Leverage Summary Level Analytics to Support Enterprise Planning?

What if you could leverage summary level cost, duration, and productivity data to support estimates for future projects, at the release and enterprise level? C-level executives, development managers, and project stakeholders are all involved at some level in project planning. They want quick access to information on a regular basis and they want web-based solutions to make it happen. So how does it all work? There are web-based analytics tools that allow you to create a centralized database for all of your projects. These tools store the data, leverage it to generate project and portfolio estimates, and then provide a communication vehicle throughout the organization to ensure that everyone involved is on the same page. It all starts with having the data in one place. 

Software Project Database

Once you have all of your project data in one place, then you can focus on analyzing the completed projects. You can compare them against industry trends and leverage a 5-star report to show how they rate on performance in the industry. The initial measures to focus on would be size, duration, effort, reliability, and productivity. A project's productivity will be calculated automatically once you have entered the size, duration and effort. We call this measure a Productivity Index. This measure can be compared to industry and used as a benchmark to measure process improvements over time.  These numbers give you a quantitative picture of your current project environment.

The 2017 Software Almanac: Development Research Series

QSM Software Almanac: 2017 Edition

Software plays an increasingly vital role in our everyday lives. It powers everything from autonomous cars and aircraft, life-saving medical equipment, and the data that allows the government to protect our country. When companies develop software, there’s no room for error. 

That’s why software predictive analysis and estimation are still extremely important. Last year, with the release of the 2016 Software Almanac, we learned that the last 35 years of predictive analytics and estimation principles were still incredibly relevant for providing reliable and applicable business intelligence for implementing successful software projects.

This year’s version of QSM’s annual Software Almanac further strengthens those findings. The 2017 Software Almanac builds on the principles identified in last year’s publication and highlights the dangers of not applying predictive analysis and estimation processes.   As stated by Angela Maria Lungu, Almanac Editor and Managing Director at QSM, these principles can be a “double-edged rearview mirror.” If you move forward without applying the historical principles of estimation and analysis correctly, their value is diminished.   Here’s what else you can expect from this year’s Almanac:

New Article: Big Rock Estimation in Agile

Agile Big Rock Sizing

Big Rock Estimation: Using Agile Techniques to Provide a Rough Software Schedule / Resource Estimate is the third article in the QSM Agile Round Table series.  The QSM Agile Round Table was formed to discuss the role of estimation in agile environments.  QSM customers shared their questions, challenges, and experiences on the relevance and benefits of scope-based estimation in an agile environment.  The Round Table spent several meetings on the key topic of sizing an agile release. The discussion centered around two main questions:

  1. How can you determine the size of a release early in absence of a “big upfront requirements phase,” and thus when the requirements are only known at a very high level and subject to refinement and change?
  2. How can you determine size in a consistent way across multiple products, projects, and agile teams so that you have good historical data on which to base an estimate?

This and the next article in the QSM Agile Round Table series are based on those discussions. Aaron Jeutter, a participant in the Round Table from Rockwell Automation, presented the technique of “Big Rock Sizing.”  This technique is used at Rockwell Automation for early sizing and estimating based on high level requirements that will be refined using agile techniques as the work progresses.

Agile Development and Software Estimation: Two Processes That Go Great Together

This post was originally published on Linkedin. Join the QSM Linkedin Group and Company Page to stay up-to-date with more content like this.

New approaches to software development can sometimes seem at odds with the needs of business customers. For instance, ardent practitioners of the agile development methodology continue to advocate for rapid response approaches and the need for constant iteration to solve complex problems. On the other hand, companies and customers are demanding a strategic approach that provides insight into process, timing, and costs.

So, which of these yin and yang scenarios should developers employ? The answer is “both.”

Enter scope-based software estimation, which I maintain can be a powerful tool to ensure that projects remain on course and on budget. It is possible for schedule and budget estimation to be achieved without sacrificing any of the things that make agile development so potent.

Not everyone feels the same. Some would argue that there’s simply no place for estimates in an agile development world; that estimates cannot coexist with agile or “lean” methodologies like Scrum, which encourage teamwork, speed, and communication without constraints.
