using 360 degree feedback is a part of what type of process
360-degree feedback Organizations have most commonly utilized 360-degree feedback for developmental purposes, providing it to employees to assist them in developing work skills and behaviors. However, organizations are increasingly using 360-degree feedback in performance evaluations and employment decisions (e.g., pay; promotions). When 360-degree feedback is used for performance evaluation purposes, it is sometimes called a "360-degree review".
Spiral model This model was first described by Barry Boehm in his 1986 paper "A Spiral Model of Software Development and Enhancement".[2] In 1988 Boehm published a similar paper[3] to a wider audience. These papers introduce a diagram that has been reproduced in many subsequent publications discussing the spiral model.
