Which Software Sizing Metrics Are Best for Your Type of Work?

The size of your house is measured in square feet, and the bigger the size, the more time and money it will take to build. The same principle applies to software development projects. Not only do time, effort, staff cost, quality and productivity increase with software size, they increase exponentially. So, what's the best unit for quantifying software size? You're probably using one or more of these familiar function units. Which one is best for you?

 

 

In Episode 5 of our video series, Software Size Matters Why Quantifying Software Size is Critical for Project Estimating, Tracking, and Performance Benchmarking, we take a closer look at sizing function units and how to capture complexity. In previous videos, we discussed why quantifying software size is important, what software size is and is not, and how to use different sizing methods. In Episode 3, we said that the sizing method you choose is largely determined by where you are in the development lifecycle because that dictates the amount of data available. When choosing a function unit, a good question to ask is what type of work will you be performing?

New Video: Negotiating Realistic Cost & Schedule Targets with Agile Estimation

In agile development, it's not unusual for software teams to have a fixed schedule or budget before any work begins. This is great information for stakeholders, but what if those targets are unrealistic? What if there were a way to evaluate trade-offs early in the decision-making process, before any detailed planning occurs?

With a top-down estimation tool like QSM's SLIM-Estimate, your scrum teams can quickly determine how much functionality they can deliver in a planned release schedule. If that target schedule turns out to be unrealistic, you can leverage SLIM-Estimate's time-tested models to calculate the impact of trade-offs. What happens if you add more people to the project? If the schedule is non-negotiable, how much functionality can you deliver in that period of time? SLIM-Estimate provides you with visualizations that are powerful when presenting to senior-level management and stakeholders. Plot your estimates against relevant agile trendlines from QSM's database of over 13,000 projects (the largest of its kind) and you can see how your estimates check out against the industry.

The video above shows how to use this powerful tool to generate defensible agile estimates you can present to stakeholders early in the planning process. Having data-driven information like this at your fingertips will allow you to plan and negotiate, and maybe even avoid disaster.

Upcoming Webinar: Larry Putnam, Sr.'s Legacy and Understanding the Physics of Software Projects

Larry Putnam, Sr.'s Legacy and Understanding the Physics of Software Projects

On Wednesday, Nov. 3 at 1:00 PM EDT, Larry Putnam, Jr. will present "Larry Putnam, Sr.'s Legacy and Understanding the Physics of Software Projects."

QSM was deeply saddened by the passing of our founder, Larry Putnam, Sr. just a few months ago. Larry's left behind a 40 year legacy in the software estimation and measurement field. His models were the basis for our SLIM-Suite of tools and many of his discoveries about the behavior of software projects still hold true today. In this webinar, his son and QSM Co-CEO Larry Putnam, Jr. reviews Larry Putnam, Sr.'s original research and the data it was based on. He then explores if that original research continues to stand the test of time when compared with data derived from modern development approaches. He also shows how modern agile development practices exploit some of the laws Larry discovered over 40 years ago. Finally, he discusses the role of estimation in today’s increasingly agile world.

QSM's Most Popular Resources of 2020 - Estimation, Sizing, Cloud Migration, Agile and More!

Top Software Estimation Resources in 2020

This year has brought many challenges. Many of us have pivoted to working remotely, trying to maintain open communication with our teams while confronting new business problems presented by COVID-19. At QSM, we've made it our goal to provide the resources our clients need during this period of uncertainty, whether it's online support, consulting, or virtual training. We've also worked to continue offering a steady stream of free resources to the online community, such as webinars, white papers, and blog posts. So as we close out 2020, we wanted to take a moment to highlight a few of our most popular. 

We'll start with one of our most widely-attended webinars to date, "Taking Software Estimation and Planning to a Higher Level." Being able to generate estimates early before detailed planning takes place is essential and can have a major impact on annual budgeting, resource allocation and cost and schedule overruns. A useful presentation if you're new to estimation or if you're a seasoned estimator, this PDU-approved webinar summarizes best practices for top-down estimation and how to leverage estimation tools. Make sure and watch until the end to catch the lively Q&A session from our audience!

How Does Agile Quality Compare?

During a recent consulting engagement, a customer asked if the QSM defect discovery model applied to Agile projects.  Of course, the best (and only) way to determine this was empirically.  From our database we extracted a sample of business IT projects that had completed since 2013 that recorded pre-implementation defects.  81 of these projects were Agile and 354 did not specify Agile as their development methodology.  We created average trend lines for both datasets and they displayed very similar patterns that conformed to the QSM defect discovery model.  This allowed us to answer our customer’s question affirmatively.

Agile Quality

Having a large project sample at hand and being curious, we decided to compare these metrics:

  • Mean time to defect (which measures the average time a system runs defect-free in the first month after implementation)
  • Average development time in months
  • Staffing
  • Cost/effort

Agile Quality

In a nutshell, the Agile and non-Agile projects used very similar staff sizes.  The Agile projects completed sooner and expended slightly less effort.  Quality was where the two project sets differed significantly.  Pre-implementation, Agile projects recorded fewer defects than non-Agile ones.  However, post-implementation the non-Agile projects operated longer between discovering defects in production than did Agile projects.

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.
