We can always try to delay the decisions until they are based on facts because corrections are difficult in the software industry, as we may need approvals and it may cost us money as well. In software development organizations, developers may feel pressurized to meet stringent timelines and end up writing sloppy code, which may result in more defects. Similarly, if testers are overburdened with work, they will not be able to share their findings with developers on time. In the meanwhile, developers keep on writing code thereby increasing backlog for testers. An organization can easily overcome these situations by having a better understanding of their tester’s/developer’s capacity. Lean software development works by first identifying value streams and then visualizing them.

The key concept here being value – by eliminating waste, one keeps only that which creates value. There are plenty of benefits to using the Lean method in a software development environment. One main benefit, as we discussed above, is the reduction of wasted resources, which can include personnel hours, overhead costs, software subscriptions, and overall overhead. The less “lean” a team is, the more time they will spend on useless features and bloated codebases. It always leaves room for improvement by postponing irreversible decisions until all the needed experimentation is done. As much info as possible is gathered until you’ve checked and examined your requirements comprehensively and there are no doubts about their relevance.

Version control and scripted builds create knowledge by consolidating all team project knowledge into a single place. They eliminate waste because manual work is saved by automating builds and build quality in because automating builds eliminates a source of errors. The second vicious cycle Lean teams need to be aware of the need to avoid is excessive testing. If testers are overloaded, testing cycles and feedback loops are extended. Longer feedback loops increase the chance sub-standard code continues to be produced in the meanwhile.

The idea is that a team creates a high-quality product from the get-go without expecting somebody else to correct the errors in the final product. Today, Buffer boasts over 1 million users on its social media management platform. Lean software development relies on tools such as Refactoring, Test Driven Development, Pair programming, incremental development and feedback, and makes use of automation wherever possible. In this guide, we will clearly define the concept of Lean development, including outlining the seven Lean Principles of Lean Software Development and how to apply them in software development.

What Is Lean Software Development?

«Respect for people» also relates to giving people the responsibility to make local decisions about their work. Also, leaders should include team members in the creation of a shared vision. Lean development can be difficult to implement because it requires you to change how you work, which means changing a developer’s habits and routines. This requires buy-in from all stakeholders on the team—people need time and energy before they are willing to change their habits. As the title suggests, lean methodology is not perfect and has a certain number of disadvantages. Processes that create burnout, exhaustion, or fuel disharmony between people or levels of the business are just as problematic, if not more so, than a defective piece of equipment.

Such an approach allows us to incrementally enhance a piece of software based on the customer feedback we collected from real customers and ditch everything of no value. As practice showed, however, such an approach often led to a catastrophe. It made engineers spend too much time building complex, monolithic systems packed with unneeded features. It restrained them from adapting the software to the ever-changing environment and client requirements.

Similarities between agile and lean

Lean software development teams are left to decide on their own practices based on the specific needs of the project, as long as they promote the application of Lean principles. Because the Agile frameworks are compatible with Lean software development principles, they serve the purpose of providing a process of established practices. Lean software development is a concept that emphasizes optimizing efficiency and minimizing waste in the software development process.

The main goal of being lean is to increase the value to customers by reducing waste (Poppendieck, M. & Poppendieck, T., 2003). It seeks to empower and engage teams to deliver value in an iterative and incremental way to customers. In Lean, deliver fast is about avoiding falling into the trap of “more haste, less speed”.

The Benefits of Using Lean Software Development

In the following articles, we will briefly investigate why using the principles of lean software development (LSD) is highly valued and beneficial in the modern IT sphere. Key principles of a custom Software development company include avoiding non-productive activities and delivering quality. Teams are empowered to consider all factors before finalizing decisions. Identifying bottlenecks and establishing an efficient system is important. Human respect and communication are key to enhancing team collaboration.

Toyota determined that people on the factory floor should have the power to pause production if they spotted a potential problem to keep minor issues from ballooning into major roadblocks. In software development, this could lean software development methodology look like team members finding a bug and pausing deployment to fix the code — without necessarily getting approval from a manager first. Lean development is a methodology that has its roots in the manufacturing sector.

With a focus on delivering value to the customer, teams are better equipped to avoid wasting time and resources on features that do not provide value or that are not important to the target audience. Lean software development principles originated from lean manufacturing, where the ultimate goal had always been a simplified, standardized pipeline production that requires no knowledge gaps and rare modifications. Therefore, when Lean’s “amplified learning” concept was introduced to a physical business, it was a game changer. Various tactics are used in lean and all related lean and agile principles and development types to ensure that quality is maintained throughout the software development process. Every small iteration, each loop is followed by an immediate assessment. Lean software development is a methodology that focuses on increasing efficiency and improving quality while reducing costs.

• The Scaled Agile Framework (SAFe®), for example, brings in values of both agile and lean and applies them to large organizations.
• There are a number of benefits to using lean development, including faster software delivery, improved quality, and reduced costs.
• Lean software development relies on tools such as Refactoring, Test Driven Development, Pair programming, incremental development and feedback, and makes use of automation wherever possible.
• It seeks to empower and engage teams to deliver value in an iterative and incremental way to customers.
• At the same time, you should not get carried away with plans and regulations to keep flexibility.
• If you wish to outstaff your software development process, you can get your dedicated team then apply lean development philosophies to get your desired results.

The waste eradication mindset of lean is sometimes equated with cost-cutting measures. A complex organization with many teams building many products needs more process to ensure consistency and quality than a fledgling startup. Companies operating with dynamic market forces will tolerate variability if it means faster delivery. In the original lean manufacturing model, a bottleneck might be resolved by establishing routine preventative maintenance for a piece of equipment. Lean practices help you spot this bottleneck so you can adjust workloads and team capacity.

Lean Development Methodology

Practically, keeping the defer commitment principle means avoiding planning in more detail than necessary before it’s necessary ie. Months in advance when things could change and so that planning has to be redone. Minimise wait states by reducing task and context switching to avoid loss of focus and knowledge gaps. It wasn’t until 1988 that “The Toyota Way” was rebranded as “Lean”, with the term coined by John Krafcik’s 1988 article, “Triumph of the Lean Production System”.
