The forming–storming–norming–performing model of group development was first proposed by Bruce Tuckman in 1965, [1] who said that these phases are all necessary and inevitable in order for a team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results. Tuckman suggested that these inevitable phases ...
Situational Leadership Theory, now named the Situational Leadership Model, is a model created by Dr. Paul Hersey and Dr. Ken Blanchard, developed while working on the text book, Management of Organizational Behavior. [1] The theory was first introduced in 1969 as "Life Cycle Theory of Leadership". [2]
For example, Poole (see below) found in his empirical research that seemingly complex patterns of behavior in group decision-making result from the interplay of life-cycle and teleological motors. An important observation made by McGrath and Tschan in 2004 regarding the different models of group development found in the literature is that ...
Change management efforts about rationale and positive or negative impacts of changes; Training on details of the new or revised information system and work system; Conversion to the new or revised work system; Acceptance testing; As an example of the iterative nature of a work system's life cycle, consider the sales system in a software start-up.

In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [ 3 ] The waterfall development model originated in the manufacturing and construction industries, [ citation needed ] where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in ...
The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard. [2] The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework, or project life cycle development. It describes the activities to ...
