Lean & DevOps

• to introduce these concept do the exercise

  1. Eliminate Waste (avoid unnecessary tasks, excessive inventory, errors)

  2. Deliver Value Quickly (promote continuous flow, limit work in progress)

  3. Optimize Learning (continuous improvement and rapid feedback)

  4. Defer Important Decisions (wait for the right information)

  5. Give Teams Autonomy (promote empowerment and self-organization)

  6. Build Quality from the Start (integrate quality at each process step)

  7. See the Whole System (maintain a global vision and improve the entire workflow)

Lean originates from the Toyota Production System (TPS), developed in Japan during the 1950s-1970s. Its main objective was to reduce waste (muda), improve quality, and optimize processes to produce more efficiently.

Agile and Lean are closely related. Although they are two distinct approaches, they share several common principles and have influenced each other.

Connection between Lean and Agile

💡 Lean has strongly influenced Agility, particularly in how teams work and adapt. Here are some points of convergence:

Scrum, Kanban, and Lean

Some Agile methods, like Kanban, come directly from Lean. Kanban adopts workflow visualization (with the Kanban board) and continuous process optimization.

Lean vs Agile: Key Differences

• Lean is more process management and systemic improvement oriented

• Agile is more focused on software development and project management with an iterative and collaborative approach

🧐 Dev(elopers) + Op(erations)
🧐 CICD: Continuous Integration and Continuous Deployment covers the automation of the entire software product development and deployment process.

The DevOps approach is a methodology that dates back to around 2010 and aims to implement the CICD approach in order to reduce the time to production for a modification while guaranteeing high software quality.

This approach is based on collaboration between developers and system engineers. These teams seek to automate deployment, monitoring, and incident management as much as possible. The operational vision must be present from the early stages of development.

This approach ensures better management of security and long-term application support.
