Why you should be using GQM to measure software quality and value
Amassing metrics or using an old set of metrics that a project manager or IT manager dug up is unlikely to provide value, and can even harm the effort. Rather, over time, software teams should define a small set of the most valuable “evergreen” metrics and retire the old ones that no longer answer pertinent questions. GQM, the initialism for “goal, question, metric”, is an established goal-oriented approach to software metrics to improve and measure software quality. GQM must be applied top-down and focus on goals and models. An organization must identify goals and trace those goals to data intended support to those goals operationally.
- The technical storage or access that is used exclusively for anonymous statistical purposes.
- In the software realm, since the first bit of software code was executed successfully in 1948, companies have striven to boost their software’s value and quality, often with mixed results.
- Neglecting to share the actions taken as a result of employee surveys.
- New Gartner research outlines how to put numbers to the concept, what meaningful action looks like from leaders, and potential pitfalls to avoid in the process.
- The GQM approach fosters learning and improvement—what we learn from one initiative informs us about what to do differently or better with the next.
- This shortcoming has obstructed efforts to develop a unified and coherent metric that tracks overall DEI progress over time.
- Gartner advises using a shorter, just-in-time pulse approach.
Questioning helps identify responsibilities, constraints, and prerequisites. It also reveals interrelated goals and their purpose in the context of the initiative being questioned. Novel application of GQM towards business data are described. Specifically in the software engineering areas of Quality assurance and Testing, GQM is used.
When undertaking an Agile transformation, there is a need to collect data to demonstrate progress and show improvement, but where does one even start? Common Agile metrics approaches do well at measuring team velocity and throughput but can sometimes overlook the requirements of executive sponsors, product management, and other key stakeholders. This problem is often rooted in a lack of understanding about what business goals are driving decision making throughout the organization and what questions we should be answering with the metrics we collect.
The Goal/Question/Metric method: a practical guide for quality improvement of software development
First, leaders should spend time interviewing areas of the organization that scored relatively well, not just hotspots. These areas may have suggestions for further improvement as well. Also, before the survey, leadership teams may have already spotted challenges, for instance, consistent conflict resolution.
Goals are developed from policy and strategy, process and product descriptions and viewpoint to develop the measurement. Very informative and thorough about the importance of Metrics, monitoring, Reviews, and retrospective in order to improve processes for upcoming and ongoing projects. One of the most valuable aspects of the GQM approach is its ability to identify for software teams exactly what constitutes each element. Organizations have been measuring output in some form and using it to fine-tune their efforts for ages, yet every generation seems to struggle to identify key metrics.
Different points of view can make it easier to decide which model applies best to your environment. There’s no doubt that in 2021 and beyond, companies will continue to devote more attention and resources to advancing diversity, equity, and inclusion . Unfortunately, many organizations still struggle to measure the impact of their strategies and communicate that impact to a growing number of stakeholders.
In the software realm, since the first bit of software code was executed successfully in 1948, companies have striven to boost their software’s value and quality, often with mixed results. An abstraction sheet is a one-page summary of a GQM plan that is used for structuring the presentation and interpretation of measurement data during feedback sessions. The most common and popular mechanism for goal-oriented software measurement is the Goal Question Metric approach which is presented in this article in combination with examples from GQM application in industry. A model is proposed, named ‗Optimum Measure Set Decision Model ‘, which is an extension of GQM paradigm based on a heuristics approach, which aims to provide the optimum set of measures from a large number of possible measures. This paper examines how a stakeholder driven Goal-Question-Metric measurement framework was derived and empirically validated with a survey from seasoned software professionals.
As with any new approach, innate resistance will be your greatest challenge. Reassure your team this approach won’t require them to give up the tools they currently use. Once you’re ready to go, tease your team with the idea that a new approach is going to make their jobs easier and their code cleaner.
As employees react to disruptions at work, at home, and in the world around them, feelings and opinions can change faster than an annual engagement survey can detect. Many organizations are still navigating a relatively new hybrid work environment as well. More than 1,600 CEOs have signed onto the CEO Action for Diversity & Inclusion Pledge, and 40% of companies discussed diversity and inclusion in their Q earnings calls versus only 4% the same quarter a year prior. According to Gartner research, the number of HR leaders identifying DEI efforts as a top priority was 1.8 times higher in 2020 than in 2019. Gartner analysis reveals an almost 800% increase in job postings for dedicated diversity recruiters. Here, goals create quality factors, an extension of the original concept to explicitly include a wider varienty of objects.
To get your team started with the GQM methodology, position it as an exciting opportunity rather than just another approach they need to master. If buy-in is required from upper management, show how this approach will result in better software, faster. A framework for structured measurement process, called Structured Prioritized Goal Question Metrics is discussed and a case study conducted in a CMMI Level 5 certified company is conducted in order to validate this framework. Needs to review the security of your connection before proceeding. So this is how questions and metrics are specified for one goal and for each goal in the scenario, a similar procedure is to be performed.
System Development Life Cycles: Phases, explanations, and methodologies
GQM is based on the theory that all measurements should be goal-oriented. There should be some rationale and need for collecting measurements, which in this case is software improvement, rather than collecting for the sake of collecting. Questions are then derived to help refine and articulate the goal. They specify what you need to know that would indicate whether the goal is being achieved. All things security for software engineering, DevOps, and IT Ops teams. Stay out front on application security, information security and data security.
When employees see firsthand the impact the survey has had, they will be more likely to share their honest opinion in the future. With these survey results, leaders can create a baseline measure of employee perceptions and look for pockets of inconsistency, both in variability within teams or more broadly between parts of the organization. They can also look at how demographics within their own workforce compare. In an era where companies are paying more and more attention to diversity, equity, and inclusion , inclusion remains the most difficult metric to track. From new research, Gartner developed the Gartner Inclusion Index to measure what true inclusion looks like across an organization. The authors outline how to use the Gartner Inclusion Index to measure employee perceptions of inclusion, what effective action looks like from leaders, and common pitfalls to avoid.
Validation on an Approach for Improving Existing Measurement Frameworks
This means that there is always a purpose with the defined measurements. A Six Sigma framework, such as DMAIC, forces us to pay careful attention to the definition of Critical-to-Quality characteristics , Performance Standards , Data Collection Plan, and Measurement System Analysis. The Define and Measure phases are particularly important in defining the right problem to solve and setting a SMART goal.
The everyday work of the software development specialists coupled with specialized vocabulary usage. Situations of misunderstanding between clients and team members could lead to an increase in overall project time. To avoid such unfavorable scenarios, we prepare the knowledge base.
Ask them to read this article, then hold a Q&A session to address concerns. Finally, plan a kick-off meeting to boost optimism and confidence. It is a proven mechanism for eliminating defects, improving overall project planning and reducing project costs. Goals should be expressed in terms of beneficial outcomes such as predictability, early ROI, faster time to market, improved quality, and lower cost. Get up to speed fast on the techniques behind successful enterprise application development, QA testing and software delivery from leading practitioners.
For example, functionality enabled as part of defect resolution was often perceived as a new feature and not a necessary improvement. By enhancing GQM with SEMS, the software industry may carry out a G QM-based measurement project more efficiently and effectively and be compared and benchmarked among projects and organizations. One reason for unclear goals or metrics lies in the lack of understanding of statistical concepts such as variation, sampling, and process stability. Unless people understand how a measured characteristic depends on the measurement method or the difference between special cause and common cause variations, they will not recognize that the goal or metric is unclear.

It is based on the Goal Question Metric paradigm and adds the capability to create measurement programs that ensure alignment between business goals and strategies, software-specific goals, and measurement goals. If leaders receive results several weeks or months after the survey, then report back action plans months after that, the timeline becomes too long to be helpful. Gartner advises using a shorter, just-in-time pulse approach. HR leaders can create a sample report in advance and use it to train their partners in different regions and/or business units on how to interpret and present the results. A metrics program should drive improvements, and as the system improves, teams must reevaluate the system and identify new goals. Ironically, a very effective methodology for defect resolution, the goal-question-metric approach, has existed for more than 40 years.
Questions connect the object of measurement to a quality issue. Tried and tested techniques such as data-flow and object-oriented models are covered as well as some promising new ones and are all based on real systems descriptions to demonstrate the applicability of the approach. Goals Question Metric approach is combined with other approaches to analyze whether goals can be achieved or not. Organizations like NASA and Motorola have used the GQM approach to improve their processes and ensure that goals are achieved as per requirement. Setting a goal for an initiative is never easy, especially when you consider the different quality models that are always in play.
The Gartner Inclusion Index utilizes a broad and multi-faceted definition of inclusion and addresses the related concept of diversity by devoting one category to employee perceptions of representation. While diversity and inclusion are distinct concept — and can be powerful on their own — only when combined can organizations achieve desired outcomes. By including diversity in the index, organizations can take action by understanding how employees perceive diversity alongside the other facets of inclusion. Employee feedback is also the most useful data source for measuring inclusion, especially when leaders can use a “pulse,” a quick survey, to check in with employees without adding to distractions. The challenge, however, is in first establishing the right metrics and then asking the right questions.
A detailed analysis of how I code provided insight on poor practice. Measurement also helps, during the course of a project, to assess its progress, to take corrective action based on this assessment, and to evaluate the impact of such action.

GQM approach has three levels – Conceptual level, Operational level, and Quantitative level. Metrics are an extension over quality measures because they explicitly include subjective and objective measures. Not necessarily missing from McCall’s model but not explicitly called out either.

But although organizations have found ways to successfully measure and track diversity, they haven’t been able to do the same for inclusion. This shortcoming has obstructed efforts to develop a unified and coherent metric that tracks overall DEI progress over time. To effectively track inclusion, organizations must measure employee sentiment with a considered definition of inclusion, ensuring the organization can act fast on the results. New Gartner research outlines how to put numbers to the concept, what meaningful action looks like from leaders, and potential pitfalls to avoid in the process. Utilizing a framework, like the Gartner Inclusion Index, can provide some hugely helpful insights and serve as a benchmark across time.
