DAD – Disciplined Agile Delivery

DAD - Disciplined Agile Delivery

The DAD consist of a number of pre-configured hybrid lifecycles to look into. Delivery lifecycle Agile lifecycle Lean lifecycle Continuous Delivery: Agile lifecycle Continuous Delivery: Lean lifecycle DAD’s Exploratory (Lean Startup) lifecycle DAD’s Program (team of teams) lifecycle.

Waterfall is one of the most well discussed software development lifecycle methods out. Depends on the view, it says contradict the Agile way of control software development. The characteristics of waterfall is to build software on a so called linear sequential life cycle model. With simple words, the development process is broken into steps. Each […]

User Story

User Story

In a culture, normally agile, where there are product owners, the requirements is written in User Stories. To be frank, one argue that the User Stories is not requirements. They just describe what the product owner wants, at the moment the story is written. It’s prone for change, due to changed needs. The stories are […]

INVEST Requirements


Similarly to SMART Goals, the User Stories within software development says to be INVEST. INVEST is a widely accepted (expected) set of criteria, or checklist, to assess the quality of a user story (common in agile). If the story fails to meet one of these criteria, the team may want to reword it, or even […]

Spiral Model (SDLC)

Spiral SDLC

The spiral model starts with an initial pass through a standard waterfall life cycle, using a subset of the total requirements to develop a robust prototype. After an evaluation period, the cycle is initiated again, adding new functionality and releasing the next prototype. This process continues, with the prototype becoming larger and larger with each […]

V-Model (Software Development Lifecycle)

SDLC V-Model

This model might rather fit into a concept than an actual framework or methodology. Instead of Waterfall methodology where all phases go downwards, V shape expect a matching verification phase before allow to go on – resulting in phases being “cleared” iteratively in smaller work batches. Like waterfall, the model is quite strict and could […]
