Lean Software Development and the 7 Principles That Drive It

At the end the integrity should be verified with thorough testing, thus ensuring the System does what the customer expects it to. Automated tests are also considered part of the production process, and therefore if they do not add value they should be considered waste. Automated testing should not be a goal, but rather a means to an end, specifically the reduction of defects. Developers launch a product quickly, receive customer feedback fast and use that feedback to create a strategy for improvement. The idea behind this approach is to fail fast and learn from the results. This strategy contrasts with other methodologies used to design complex products.

They’ll work within small timelines to get you a version quickly so they can garner feedback and make iterations. Minimize time to eliminate anything that might create waste. If there are bugs, fix them immediately instead of creating a backlog. This ensures that the quality of the product remains intact.

Contribute to the build of a car was considered ‘waste’ and was stripped from the production process. Hinted at with the previous principle, Lean recognizes that software is more than just the sum of its parts, but also the interactions between the parts. Optimizing the whole looks at dependencies and builds for collaboration to ensure that every employee is incentivized to optimize for the whole – not just for their part. Perceived integrity – the elements of the software that are obvious to the end-user . This form of integrity prioritizes the understanding of customer needs and effective communication of requirements. When it comes to healthy team development, there are a lot of resources available to improve leadership skills or work on team communication.

By streamlining the software development process, Lean development helps organizations save time and money while delivering better quality products. Lean is the process of applying a scientific experimentation approach to find optimal solutions to user problems. On the other hand, the Lean Agile methodology focuses on the people who use your application.

Rapid Feedback Loops

Speed assures the fulfilling of the customer’s present needs and not what they required yesterday. This gives them the opportunity to delay making up their minds about what they really require until they gain better knowledge. Lean software development is a translation of lean manufacturing principles and practices to the software development domain. Adapted from the Toyota Production System, it is emerging with the support of a pro-lean subculture within the agile community. Lean offers a solid conceptual framework, values and principles, as well as good practices, derived from experience, that support agile organizations. The last three Lean principles highlight some of what the Lean methodology has in common with Agile.

The process of detecting and reducing bottlenecks and pain spots is known as flow improvement. Teams can produce features much more quickly if they think about and improve the internal delivery process. It’s based on the idea that every business represents a value stream – the sequence of activities required to design, produce, and deliver a product or service to customers. If our goal is to deliver as much value to our customers as quickly as possible, then we have to optimize our value streams to be able to do just that. To understand how to optimize our value streams, first we have to properly identify them.

Aligning The 7 Lean Principles Into Our Software Development Projects:

Carefully monitor the demand and the feedback and deliver the benefits they need, instead of creating random features and aggressively marketing them. For instance, development shouldn’t be blocked by a lack of design resources. Releases to production shouldn’t be blocked by a lack of quality assurance engineers, etc. The system should be balanced, and the Kanban board helps to identify these issues visualizing the workload at different stages. Your team implements it screen by screen, and after the first screen is ready, you can release it. It doesn’t make sense on its own – it’s too interconnected with other steps.

  • So, is the answer to use one methodology, or combine both?
  • You can see how by doing this Toyota put a lot of power into the hands of its people.
  • Another benefit of the pulling concept is that you don’t implement something in advance “just in case,” but rather address the issues right in time.
  • It’s not simply about implementing a new method; it’s also about having the right people to make it work.
  • It also results in a better workflow because every team member knows what they are responsible for.
  • Your product should have minimum features to be delivered quickly while also having enough value to meet your business objectives.

Cut corners, deprioritize non-essential work, and avoid perfectionism. Schedule decisions that can’t be reversed for the latest date and time possible. Take your time lean development process and gain as much knowledge as possible so you can avoid costly and time-consuming changes. You can reduce the cost of change by making decisions at the last minute.

User-Focused Design

This way, engineers will not need to fix problems that could have been prevented, reducing the testing time and effort needed to fix bugs at a later stage of development. The lean methodology is risky, as instead of finding and fixing problems earlier, it encourages taking risks and solving problems even before they arise. This way, the team may be taking an unknown threat, potentially resulting in damages. Lean encourages testing as often as possible – from unit tests within an application down to end-to-end tests responsible for checking the work of an entire application.

Waste can be a result of anything that does not add value. For example, when you’re building features that users don’t need or features that don’t match what customers want. Don’t treat them like cogs in an assembly line; the seventh principle of lean manufacturing is respect for people. This means that you need to understand each individual’s needs and not treat them like cogs in an assembly line. You should make sure your employees are treated fairly and with dignity, as well as give them the freedom to make decisions about how they do their work. The focus on delivering value to customers early often helps you get feedback on whether your product is useful and how you can improve it.

How We Align Lean Principles in Our Software Development Process

When testers are overloaded, it creates long delays between developers writing code and testing, and giving feedback. This means that developers continue writing code that can be defective, resulting in many bugs and requiring more testing. It means we need to focus on improving the entire process of delivering software and not just the development phase.
