Lean Software Development Principles You Should Know Before Hiring A Team

Lean software development principles are best practices borrowed from the manufacturing industry. These principles were drawn from the lean development methodology of Toyota’s production system.

These have gained popularity among software developers within the agile community. Of course, there are differences between lean manufacturing and lean software development.

For example, lean manufacturing focuses on producing physical goods. But, in lean software development, the value is in the developer’s mind.

Still, applying the principles of lean development to software development has many benefits.

The Origin Of Lean Software Development Principles

The term lean software development comes from a book, written in 2003 by Tom and Mary Poppendieck.

Lean software development principles are a framework of values and best practices. These boost the success of the software development process.

Organizations that employ the agile methodology created the lean development methodology.

The Seven Principles Of Lean Software Development

There are seven lean software development principles. For the greatest benefits, it is best to hire a development team that uses these lean principles.

This article explains each principle and its application in the software development process. 

Lean Development Principle 1: Eliminate Waste

Waste is anything that inhibits the ability to deliver what the customer wants in the best time frame. To eliminate waste, one must be able to recognize it and take necessary action.

To recognize waste ask yourself:

  • Is it possible to bypass an activity to increase development speed?
  • Is it possible to achieve the end goal without it?

There are seven wastes listed in Toyota’s school of lean manufacturing. These are:

  1. Waiting
  2. Defects
  3. Over-processing
  4. Motion
  5. Unnecessary transportation
  6. Inventory
  7. Overproduction

Collaboration is necessary to identify and remove waste from a project. Hold regular meetings and allow team members to share findings and suggestions. 

This amplifies team learning and facilitates the implementation of improvements to the code.

How Waste Impacts Lean Software Development

Here are a few examples of how waste affects software development:

  1. Unclear or constantly changing requirements: This results in rework, delays, frustration, a lack of focus, and quality issues.
  1. Unnecessary code or functionality: This results in delays in getting the software to the customer and slowed feedback loops.
  1. Starting more than can be completed: This overwhelms the team and impedes the workflow. It results in context-switching and handoff delays.
  1. Bureaucracy: This slows down development.
  1. Slow or ineffective communication: Poor communication among team members results in delays and frustration. Poor communication with stakeholders negatively impacts the reputation of the developer.
  1. Incomplete work: This prevents the team from learning from the work and does not benefit the customer.
  1. Defects and quality issues: This results in customer dissatisfaction and rework or abandoned work.
  1. Task switching: Task switching leads to delays, communication breakdowns, poor quality, and low team morale.
  1. Delays in the development process: This slows the delivery time to the customer and slows down feedback loops. 

Lean Development Principle 2: Build Quality In

Building quality into a piece of software is essential to eliminate waste. This prevents the developer from having to rework the software later.

When quality software isn’t produced it affects future tasks of the development team.

They will need to focus on fixing old work while juggling new work. This is also known as task switching, which is a costly distraction.

That is why, in lean development, quality concerns everyone. A high-quality output benefits the collective.

How can teams build quality into an app? Many software development teams have used the following lean development practices:

Pair Programming

This involves using two developers to work together on project requirements. Thus, the customer benefits from the combined skills and experience of both developers.

Test-Driven Development

This is where guidelines and metrics are set for developers before work commences. For example, setting criteria for code before writing it for the software.

Automated Testing

Automated testing handles manual processes that humans would find difficult. Automated testing speeds up tedious processes and administrative tasks. 

Lean Development Principle 3: Create Knowledge

Writing code is a difficult process yet it often helps to create knowledge. Retaining such knowledge is vital to software development companies.

This is so because it increases the delivery speed and success of future projects.

Staff retention is also sensible business practice. It is costly to hire and train new staff in the business domain.

Lean companies must follow development practices that keep knowledge discoveries within the business.

This is achievable by using a combination of the following techniques:

  • Knowledge sharing sessions to amplify learning
  • Pair programming
  • Wiki – to let the knowledge base build up in a cumulative way
  • Code reviews
  • Thoroughly commented code
  • Documentation
  • Training
  • Use of tools to manage requirements or user stories 

Lean Development Principle 4: Defer Commitment

It is wise to make careful plans. But, one must keep in mind that things do not always go according to plan. 

So, making step-by-step plans using the waterfall development methodology has become obsolete. This approach is inflexible and does not add value to the customer.

Instead of predicting the work years in advance, it is best to defer the commitment. Make small steps, and reflect on the lessons learned.

What does it mean to defer commitment? This means:

  • Not planning in excessive detail for months in advance.
  • Not committing to an idea or project without grasping the business requirements.
  • Scheduling irreversible decisions for the last responsible moment.
  • For the most part, making reversible decisions.
  • Avoiding decision-making that is difficult to reverse (locking in critical design features and code).
  • Constantly collecting and analyzing info on important decisions.

This lean methodology helps development teams create flexible software. It’s possible to adjust this is software without wrecking earlier work.

This project management approach is vital in today’s volatile industry.

Lean Development Principle 5: Deliver Fast

Faster software delivery reduces the possibility of customers changing their minds. This delivers value to the customer and minimizes waste such as work piling up in queues.

Faster delivery means faster feedback. This allows teams to adapt the software where necessary, and fast.

This increases customer satisfaction and decreases the frustration of having too much work.

What are some factors that slow teams down? They include:

  1. Thinking and planning too far ahead about future requirements.
  2. Non-urgent response to blockers.
  3. Over-engineering business requirements and solutions.

What can help teams speed up delivery?

Gone are the days of working long hours and weekends. The lean way of manufacturing and production focuses on optimizing the whole project.

It does this by:

  1. Structuring the work so that each member knows what to do.
  2. Allowing each member to solve problems and adapt to changes without asking permission.

In today’s competitive industry, speed to market can give you the edge. Lean development supports agile delivery by the following concept:

  • Build a simple solution, deliver it to customers, and enhance it incrementally based on customer feedback.’

Lean Development Principle 6: Respect For People

A company that shows respect for its staff is more likely to have a motivated team. A motivated team is quick to adjust the software to reflect changes in the environment.

Motivation is the fuel that keeps a team fired up and ready to deliver. How is this achieved?

Respect People

Develop a management style that fosters engaged thinking and focuses on creating a great product. Here are some tips to help management teams achieve this:

  1. Be proactive and respectful when communicating with those you oversee.
  2. Provide staff with the needed expertise and support to accomplish their goals.
  3. Help staff to nurture their technical ability.
  4. Practice responsible planning and control.
  5. Provide teams with general plans and reasonable goals.
  6. Express trust in the team’s ability to self-organize to meet goals.
  7. Discuss work-related issues as a team.
  8. Encourage healthy conflict.

It is hard to set up a collaborative atmosphere and keep the balance of control within a project. The key is to allow development teams to make changes, but require them to report and explain their decisions to managers and you – the client.

Lean Development Principle 7: Optimize The Whole

Every business has a value stream. This is the process to design, produce, and deliver products or services to customers.

To deliver value to the client, companies need to optimize their value streams.

Although made up of code, the software is a product of many individuals completing their part of a chain. Software system defects tend to accumulate along this development chain.

This principle focuses on improving all the software development processes to cut system defects. In effect, it is a strengthening of the chain.

Do this by:

  • Splitting big tasks into smaller ones
  • Standardizing different stages of development

Additionally, cross-functional teams are a good way to optimize the whole. With this development methodology, everyone on the team can handle all parts of the chain.

It also means that there is a variety of perspectives on problems that arise. This makes it harder for defects to permeate the software system.
