Software engineering

Software engineering is the application of engineering to the design, development, implementation, testing and maintenance of software in a systematic method

Waterfall

Prototyping

Software prototyping is the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed

Spiral

Iterative and incremental development (IID)

Iterative development model

Agile (2001)

• Agile software development describes a set of principles for software development under which requirements and solutions evolve through the collaborative effort of self-organizing cross-functional teams
  
• First coined in 2001, in the Manifesto for Agile Software Development

Lean (2003)

• Lean software development (LSD) is a translation of lean manufacturing and lean IT principles and practices to the software development domain
  
• Adapted from the Toyota Production System, it emerged from within the Agile community

Lean principles

• Eliminate waste
  
• Amplify learning
  
• Decide as late as possible
  
• Deliver as fast as possible
  
• Empower the team
  
• Build integrity in
  
• See the whole

DevOps

DevOps (a clipped compound of development and operations) is a culture, movement or practice that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes

Scrum

• Scrum is an iterative and incremental agile software development framework for managing product development
  
• It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal"
  
• It challenges assumptions of the "traditional, sequential approach" to product development
  
• It enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines involved
