Upcoming Webinar: Measuring Software Size - Insights from the Past to Guide the Future

Measuring Software Size Webinar

On March 24 at 1:00 PM EDT, QSM will be hosting a PDU-approved webinar, "Measuring Software Size - Insights from the Past to Guide the Future."

Software size measures are critical to project estimation, governance, and closeout. Methods for measuring size have been around for decades, yet many organizations still struggle to establish consistent, repeatable processes for capturing software size. Common agreement is that project size is the most important predictor of cost and schedule.

In this webinar, Laura Zuber will describe ways to measure software size and gather actual data for completed projects to improve future estimates and in-flight project forecasts.

Webinar Replay: Demystifying Cloud Migration Using Estimation

Demystifying Cloud Migration Using Estimation

If you were unable to attend our recent webinar, "Demystifying Cloud Migration Using Estimation," a replay and slides are now available.

Technology organizations spend millions of dollars each year implementing cloud-related programs. Whether the programs are in-house or vendor-related, early planning can be a major stress factor in the management of these programs. Organizations often lose big money and time while trying to carry out cost and schedule targets that were unrealistic to begin with.

Join Kate Armel and Keith Ciocco for this PDU-approved webinar as they show the value of using empirically-based software estimation tools to help mitigate risk and improve early planning and negotiation capabilities when migrating to the Cloud.

Top 5 Resources for Increasing Software Development Predictability in 2020

Top 5 Software Estimation Resources in 2019
As we enter a new decade, it's important to take a look back at where we've been. The past 10 years saw the introduction of the Ipad, Microsoft Azure, Uber, 4G networks, and Instagram. Some might look back and call this the era of cloud computing and artificial intelligence with increased connectivity and efficiency in technology like never before. But software development goals have remained largely the same: to reduce cost and time to market, increase quality and maintainability, and allocate resources more efficiently. I'm willing to bet those goals will not change in the coming decade. At QSM, we have always believed that the only way to combat the unknown is with practical measurement and metrics grounded in data from our past. As we look to 2020, let's take a look at our top 5 resources from 2019, featuring the most current insights from our industry experts on the state of software estimation and project management and development trends. 

What better way to get a bird's eye view of software development's history than with a look at long-term trends? Leveraging QSM's industry database of over 13,000+ completed projects, Katie Costantini's "Long Term Trends from 40 Years of Completed Software Project Data" took a high-level look at changes to software schedules, effort/cost, productivity, size, and reliability metrics from 1980 to 2019. The study compared insights to similar studies QSM has completed at regular intervals over the past four decades and answered questions like, 'what is the "typical" project over time?' and 'why are projects "shrinking?"

Webinar Replay: Is Software Estimation Needed When Cost and Schedule Are Fixed?

Fixed Cost and Schedule Estimation Webinar

If you were unable to attend our recent webinar, a replay is now available.

In many agile and even non-agile development environments, the budget, team size, and schedule are fixed based on an organization’s predetermined targets. This leads many project managers to question how they should proceed with target negotiations and some even wonder if they should estimate at all. The problem is, without a reliable estimate, the amount of functionality promised within the time and money constraints could be difficult to achieve. This could cause the product delivery to be short on features, or late and over budget.

Join Keith Ciocco for this webinar as he demonstrates the role of scope-level estimation tools in evaluating if targets are reasonable and in determining how much functionality can be delivered. This crucial analysis helps set customer expectations and provides data-driven leverage for negotiations.

Keith Ciocco has more than 30 years of experience working in sales and customer service, with 25 of those years spent with QSM. As Vice President, his primary responsibilities include supporting QSM clients with their estimation and measurement goals, managing business development and existing client relations. He has developed and directed the implementation of the sales and customer retention process within QSM and has played a leading role in communicating the value of the QSM tools and services to professionals in the software development, engineering and IT industries.

White Paper: Long Term Trends from 40 Years of Completed Software Project Data

Software Project Size over Time

Although the software industry is known for growth and change, one thing has remained constant: the struggle to reduce cost, improve time to market, increase quality and maintainability, and allocate resources most efficiently. So how can we combat future challenges in a world where everything is software, from the systems in your car to the thermostat in your home to the small computer in your pocket? By using practical measurement and metrics, we can get a bird's-eye view of where we've been and where we could go, while keeping us grounded in data. Leveraging QSM's industry database of over 13,000+ completed projects, Katie Costantini takes a high-level look at changes to software schedules, effort/cost, productivity, size, and reliability metrics from 1980 to 2019. The current study compares insights to similar studies QSM has completed at regular intervals over the past four decades and answers questions like, 'what is the "typical" project over time?' and 'why are projects "shrinking?"' The results may surprise you!

4 Key Studies on Team Size

Software Team Size

It seems like ever since the dawn of software development, humans have struggled with the question of team size. What team size is most productive? Most economical? When does adding more people to a project cease to make sense? So it comes as no surprise that one of the most popular articles on our website is a study Doug Putnam did in 1997 on team size, Team Size Can Be the Key to a Successful Project. The article leveraged data from 491 completed projects in the QSM Database to determine what is the optimal team size - "optimal" being most likely to achieve the highest productivity, the shortest schedule, and the cheapest cost with the least amount of variation in the final outcome. The study determined that for medium-sized (35,000 to 95,000 new or modified source lines of code) systems, smaller teams of 3-7 people were optimal. This article continues to be referenced today, especially by the agile community.

The topic of team size reappeared again in Don's Beckett study of Best in Class and Worst in Class projects for the 2006 QSM Software Almanac. To identify top and bottom performers, he ran regression fits for effort and schedule vs. project size through a sample of nearly 600 medium and high confidence IT projects completed between 2001 and 2004. On average, Best in Class projects delivered 5 times faster and used 15 times less effort than Worst in Class projects. What made the Best in Class projects perform so much better? Best in Class projects used smaller teams (over 4 times smaller, on average) than the worst performers.

New Resource: QSM Software Almanac: 2019 Edition

QSM Software Almanac: 2019 Edition

We are pleased to announce the release of the QSM Software Almanac: 2019 Edition, an essential resource for anyone involved in the planning, management, or budgeting of software and systems projects and portfolios. This year's almanac focuses on agile development and the continued relevance and application of estimation and metrics.

The 2019 Almanac presents 18 articles from several perspectives, including both private and public. These articles show that there is indeed a compelling need to apply the basic principles of software estimation to projects, regardless of the methodology used, and that traditional metrics – even sizing metrics – can and should be applied to agile projects. Over the course of this book, the authors examine agile sizing approaches, effort and productivity, estimation best practices, as well as project and portfolio management best practices. All the articles offer research and insights into the foundational skills associated with parametric estimation and adapting those existing skills to account for changing conditions.    

Much of the content in the 2019 QSM Software Almanac is derived from the QSM Metrics Database, drawing data from over 13,000 completed software projects from North and South America, Australia, Europe, Africa, and Asia, representing over 1.2 billion lines of code, 600+ development languages, and 120 million person hours of effort.

We invite you to download the full, complimentary version of the 2019 QSM Almanac below.
