Lean Software Development: An Introduction  

Lean Software Development is designed to accelerate and improve the software development process.  

The lean development approach was first introduced in the manufacturing sector as a technique to streamline production and assembly processes to reduce waste and increase consumer value.   

In truth, the carmaker Toyota established this method in the middle of the 20th century to simplify automobile production and eliminate wasting time and resources. It was initially known as the Toyota Production System.

Due to the Lean Software Development methodology’s ability to streamline the development process and force the group to ruthlessly eliminate any tasks that don’t directly contribute to the end result, many organisations have found it to be a highly effective software development technique.

However, for this strategy to be effective, a firm must have a top-notch development team and unwavering confidence in its staff. Read on to learn more about this process.

What is Lean Software Development?

Lean Software Development can also be known as the Minimum Viable Product (MVP) strategy because these two thinking methods are incredibly similar in that they both aim to accelerate development by concentrating on new deliverables.

Waste is anything that can lower the quality of the code, waste time and effort, or lower the amount of delivered business value. It could involve things like extraneous code or functionality, sluggish programming, murky requirements, or inadequate testing. 

Lean development emphasises getting rid of these elements, learning the necessary technologies, and discovering what the user actually requires.

Additionally, the cost of change is significantly lower when decisions are made last minute. To produce new apps or modifications as quickly as feasible, iterative development is used. 

Software integrity ensures the architecture and the interoperability of system components. As improvements are made quickly, organisations use lean development concepts to promote continuous improvement.

Advantages of Lean Software Development:  

  • The development team can determine what to improve once the minimum viable product has been released to the market. They can also understand how they should prioritise this task. Customer feedback is essential at this point. Thus, wasteful work and expenditures are avoided.
  • The development process is simplified thanks to lean software development techniques. It removes pointless steps. As a result, it becomes quicker, more efficient, and less expensive. It conserves the two most valuable resources—money and time.
  • Teams with empowered members are more enthusiastic. It is impossible to stress how important this is. Lean concepts eliminate micromanagement and forced implementation of decisions. Both managerial strategies are demoralising. Team members who are driven and have decision-making authority produce higher calibre work.

Lean Software Development Principles 

A few key ideas that have remained largely constant over the last few years are at the core of lean development. The principles are as follows:

  1. Eliminate waste
  2. Amplify learning
  3. Keep decision-making for last
  4. Delivering fast
  5. Empower and respect people
  6. Build quality
  7. Optimise the whole

Eliminate Waste

Eliminating waste is the first lean software development principle. Time spent developing, researching, or creating features that won’t be used and time spent maintaining software and repairing defects are some examples of waste.

Waste in the development of apps refers to anything that doesn’t provide the customer with any business value, doesn’t raise the calibre of the item being created, and doesn’t hasten the project’s completion.

In other words, this costs money but yields no return. For instance, wasted code and pointless features that waste time on development, testing, and documentation but don’t offer anything to the user or business experience.

Amplify Learning 

The Lean development principle of “amplify learning” is focused on knowledge creation during the development process, which is vital for maximising value delivery to consumers. 

The goal of lean teams that create software is to foster knowledge exchange. Peer reviews, knowledge-sharing sessions, pair programming, and other techniques help to achieve this.

The team needs a diverse set of expertise to devise a system that will benefit the customer’s business. The group must gather knowledge and disseminate it, for instance, through an assessment at the end of an iteration.

Keep Decision-Making for Last

The key takeaway from this is to put off taking any decision, especially one that cannot be undone. This is particularly true when it comes to choices that could significantly affect how well a development turns out.

Changes might often happen in a volatile context like software development. Making the wrong choices regarding the start of a development project or the next most crucial item to focus on could result from this. It can also result in inadequate data collection for the task at hand. This causes waste and calls for further work.

Delivering Fast 

Delivering rapidly is the fourth lean software principle. Quick delivery prevents waste from accruing, such as work stacking up in lines or having a lot of work in process. 

Teams can monitor the impact of our efforts and then make changes in response to our findings more quickly the faster we provide. Techniques like trunk-based programming and feature flags to enable full one-piece flow are at the cutting edge of delivering swiftly.

Empower and Respect People 

Trust and value your team. The human factor is one of the most crucial components in effective software development.

Manage individuals as skilled, motivated professionals rather than individuals with specialised knowledge of writing code or creating diagrams since software development is a mental process.

Individuals must be aware of their role in creating the product to take ownership of it, be motivated, and operate well as a team. In addition, conditions must be established so that each individual can concentrate while working on the company’s current task.

Build Quality 

Avoiding the need to rework a piece of software later is the main goal of incorporating quality into it. If teams don’t create high-quality software in the beginning, they can end up needing to manage the new work and put out blazes after it’s been launched.   

Task switching, another term for this workflow detractor, is an explicit example of lean waste since these types of distractions can be expensive.

Optimise the Whole 

The final Lean development concept encourages businesses to solve issues by evaluating a system’s performance as a whole rather than simply individual components.

Lean views organisations as networks of connected value streams, such as development, sales, and marketing, that are organised into business systems. The entire value stream should be optimised in order to provide the best value to customers, identify, and resolve issues with the supply of goods and services. 

Lean software developers begin by determining the flow of value to accomplish that. In actuality, this may be achieved by displaying the workflows of many teams on connected Kanban boards. As a result, companies may identify bottlenecks and search for solutions to problems in all of their operations. 

Lean Software Development Process

Value streams are first identified in lean software development, and then they are visualised. As opposed to manufacturing, software engineering creates immaterial products that are not touchable. Therefore, it’s crucial to graphically map such value streams to reduce waste in the process. Value stream mapping is a Lean method used to achieve this.

Analysing the value stream comes after value stream mapping gets complete. This is accomplished by identifying bottlenecks in the development process, such as useless phases and slowing down the delivery process. Then, lean software development teams begin keeping track of metrics like cycle time and lead time.

Introducing flow into the process is one of the key concepts of Lean. Therefore, the foundation of lean software development is indeed the creation of modest solutions and their prompt delivery to the customer. 

This is crucial in an industry that is evolving quickly, like software development, because it gives businesses a competitive edge. After doing that, Lean software teams concentrate on learning from their initial designs so they can keep improving them.

Wrapping Up 

Value stream mapping will assist you in promoting the seven lean principles throughout the software development process at your company, enabling your team to optimise the process as a whole and enabling you to quickly identify any areas where you may not be reducing waste or enhancing quality as you should. 

To put it another way, if you use VSM, you’ll be well on your way to producing high-quality software as rapidly and efficiently as you can.

Each Lean development principle can improve your company’s ability to produce value and keep customers happy with your goods or services by being understood and put into practice. Additionally, it can assist your company in lowering software development project risks while raising the revenue of the solutions you deliver.
