Speed Vs Quality: Which One Should You Aim for In Development?

Speed and quality are surely the top goals any software development team aspires to. Speed can help you build an advantage over slower competitors while keeping your customer base engaged. Quality ensures you’re giving your users the best experience they can get with your software.

Speedy development can bring your product to market faster.

However, this rush can sometimes lead to overlooked errors that may compromise the user experience.

Conversely, prioritizing quality might slow your release but often results in a more reliable and user-friendly product.

But if you focus too much on perfecting it, the project might take too long.

=> That’s why striking the right balance is crucial.

What is Speed in Software Development?

Speed in software development refers to the rate at which the software is developed and delivered to the market.

It encompasses several aspects, including:

• The efficiency of the development process
• The ability to meet tight deadlines
• The rapid deployment of features and updates

Speed is about reducing the time from concept to market, enabling a product to adapt quickly to user feedback or changing market demands.

Speed As The Main Objective

The rise of Agile and DevOps methodologies and processes has had quite an impact on software development. The idea of using an iterative approach to software development certainly sped things up while augmenting the development team’s flexibility and increasing the feedback instances that factor in a higher quality.

With Agile development, companies can easily get results faster with a more-than-acceptable quality. However, these methodologies have been sometimes misinterpreted or poorly implemented, leading to an obsession with speed. Things got a little distorted, to a point where some teams started to think that they didn’t need dedicated QA teams anymore. Naturally, the ones that did that sacrificed quality because speed felt more important to them.

Is that the wrong approach?Not necessarily. While having a minimum level of quality is a must for any modern software, speed as a priority can be understandable for certain projects and goals, including:

• New features for social media engagement
• New product with no competition
• A strategic product or a new feature in a stagnant market

Benefits and Risks of Overemphasizing Speed

Prioritizing speed offers several benefits, such as:

• A product can reach the market faster, which is crucial in industries where being first can define market leadership.
• Rapid development cycles allow for quicker feedback loops with users, providing valuable insights to improve the product continuously.

However, overemphasizing speed can lead to significant risks, such as:

• The potential compromise in software quality – Critical aspects like thorough testing, code reviews, and documentation might be overlooked, leading to buggy and less secure software.
• The creation of technical debt – While these might not pose immediate problems, they can accumulate over time and make future changes more time-consuming.
• Burnout in development teams – Constantly working under tight deadlines and high pressure can be unsustainable, leading to decreased productivity and higher turnover rates.

What is Quality in Software Development?

Quality in software development encompasses several vital aspects affecting your software’s overall perception and effectiveness.

• It’s reliable, functioning consistently without errors, and follows your software development KPIs.
• Quality software is efficient, using resources wisely without unnecessary lag or resource drain.
• High-quality software must be scalable and capable of growing and adapting to increased usage or changing requirements.
• It should ensure the software is user-friendly and intuitive.
• The software has to be easy to update, modify over time, and debug by following the software development best practices.
• It should perform well, which involves the software’s speed, resource efficiency, and security, ensuring data protection and resistance to breaches.

Quality As The Main Objective

There are some projects (and even entire industries) that would be wise to focus primarily on the highest quality possible regardless of how long the development takes. That’s because there are certain digital products that deal with sensitive information or handle delicate tasks that can’t afford to fail. Some of them include:

• Banking
• Financial
• Healthcare
• Retail
• IoT projects

All of them manage very sensitive and private data that needs to be handled carefully. This means that the software in charge of powering those industries need to boast a superb performance, a strong security level, and robust backup and remediation systems in case someone fails. Delivering all of those takes a lot of development time but, given what’s at stake, organizations in those fields prioritize quality over speed.

So, it’s expected for these kinds of projects and industries to take a slower development pace to provide the team with the necessary time to thoroughly test the solutions they build. In this context, QA plays a crucial role to make sure that the processes you use during the software development life cycle are as efficient as they can possibly be.

Benefits and Risks of Overemphasizing Quality

In the context of speed vs quality in software development, let’s consider the benefits and risks of focusing too much on quality.

• It leads to a robust product that users can rely on, building a solid reputation for your brand.
• High-quality software often enhances user satisfaction, fostering loyalty and potentially increasing market share.
• In the long run, investing in quality can be cost-effective, reducing the need for frequent fixes and updates.

However, overemphasizing quality comes with risks, for example:

• The most significant is the potential delay in time-to-market. You can miss out on critical market opportunities or fall behind competitors.
• There’s also the risk of adding unnecessary features or enhancements that don’t align with user needs or business objectives.
• As efforts to perfect every aspect of the software increase, so do the costs associated with development.

A Speed And Quality Balance

As you can see, going for speed or quality depends on your business goals and your overall requirements. You surely noticed, though, that while you can’t achieve both at their highest level, you can aim for a balance that doesn’t entirely sacrifice one of them. QA services play a pivotal role in achieving that balance.

The following strategies for software development can be particularly effective in effectively balancing speed and quality.

1- Adopt Agile and DevOps Development Methodology

With QA and software testing in combination with Agile and DevOps processes, you can aim for faster times to market with improved product quality.

The agile software development model focuses on iterative development, dividing projects into small, manageable segments, allowing for regular assessment and adaptation.

This approach helps quickly address changes and incorporate feedback, leading to a more responsive and user-focused development process.

Agile also promotes regular communication between developers, managers, and customers, ensuring that everyone is aligned and that the final product closely matches user needs.

On the other hand, DevOps merges development and operations to streamline the software development lifecycle.

It emphasizes automation, continuous integration, and continuous delivery, aiming to shorten the development cycle and provide high-quality software.

DevOps encourages collaboration between developers, IT professionals, and quality assurance teams.

This collaboration helps:

• Identify and resolve issues quickly
• Reduce downtime
• Ensure that the software is always operational and up-to-date

2- Include test automation and Continuous Integration

Automated testing and continuous integration are critical components that balance speed vs quality in software development.

Automated testing involves using software tools to run tests on the code automatically.

It helps identify bugs and issues quickly, reducing the time spent on manual testing.

You can run automated tests as often as you need to, ensuring new changes don’t break existing functionalities.

Continuous integration (CI) is where developers frequently merge their code changes into a shared repository.

Each merge is then automatically tested, allowing teams to detect problems early.

CI helps maintain a high-quality codebase, as issues are identified and addressed promptly.

It also supports a more collaborative and transparent development environment, where team members can see the impact of their changes immediately and work together to resolve issues.

3- Define a Risk Management Plan

Risks in software development can range from technical issues, such as software bugs or integration challenges, to non-technical issues, like changes in project requirements or delays in deliverables.

The first step in developing a risk management plan is risk identification, which involves brainstorming possible risks that could affect the project.

Once risks are identified, the next step is to assess them.

This assessment looks at each risk’s probability and potential impact on the project.

Based on this assessment, you can prioritize risks, focusing on the most likely to occur and have the highest impact.

After prioritizing risks, the next step is to develop mitigation strategies, including:

• Setting aside additional time and resources to deal with potential technical challenges
• Having contingency plans in case key team members are unavailable
• Maintaining open lines of communication with stakeholders to manage expectations

4- Ensure Your Team Well-being

A team that is overworked, stressed, or unhappy is less likely to produce high-quality work and more likely to make mistakes.

Ensuring team well-being concerns several aspects, including:

• Workload management
• Providing a supportive work environment
• Recognizing and addressing team members’ needs

A key takeaway is avoiding unrealistic deadlines and providing adequate resources and support.

A supportive work environment is one where team members feel valued and supported.

It includes having open lines of communication, providing opportunities for professional growth, and fostering a culture of collaboration and respect.

Addressing team members’ needs is also crucial.

This can involve providing flexible working arrangements, ensuring team members have opportunities for rest, and addressing any personal or professional challenges they may face.

5-Gather and Apply Feedback from Users and Stakeholders

Gathering feedback from users and stakeholders can provide valuable insights into:

• How the software is used
• What do users like or dislike about it
• What additional features or improvements do they desire

Engaging with users and stakeholders regularly helps better understand their needs and expectations.

Then, you can incorporate this information into the development process.

This could mean changing the existing features, adding new functionalities, or even pivoting the project direction.

Incorporating user feedback also helps build a loyal user base, as users feel heard and valued.

This approach can lead to:

• Better user satisfaction
• Increased adoption rates
• A more successful product

6-Consider Shift Left

The shift left is about moving the testing phase earlier in the software development life cycle left.

When you shift left, testing becomes an early and frequent activity. Testing happens before, during, and after development. In general, that means less time waiting for testers.

Good approaches of shift left:

• Test-Driven Development: TDD requires you to first write the tests for the piece of code you want to develop. Therefore, you can immediately verify the validity of your code.TDD is a good alternative if you want to reduce your time to market since it relocated the tests to the development phase rather than conducting them afterward.
• Behavior-Driven Developmen: BDD defines a common design language that can be understood by all stakeholders, such as product owners, testing engineers, and developers. Therefore, it enables all involved stakeholders to simultaneously work on the same product feature, accelerating the team’s agility.In other words, BDD stimulates cross-team collaboration while improving feature-delivery time.
• Use Static Code AnalysisStatic code analysis is the practice of checking the code without executing it. It runs through the basic code structure and ensures that the code is aligned with a number of standards and guidelines. Generally, the static analysis looks for the following issues:- Programming errors- Violations of commonly followed coding standards- Syntax anomalies- Security issuesStatic code analysis is best done via automation; otherwise, it is impossibly tedious. The software should scan all untested code in a project before it moves to QA. A static code analyzer checks code against a set of predefined standards and rules to determine if the code complies with them.If the analyzer does flag any issues, a human developer/tester will have to examine them to verify that they are not false positives. Then, devs can fix apparent mistakes and send the code to testers.

With these suggestions, your project can have the best of both worlds and you can start leaving behind the sterile speed vs. quality debate.
