SDLC 面试题与答案

Question: Explain when to use the V-Shaped model.

Answer: The V-shaped model should be used for small to medium sized projects where requirements are clearly defined and fixed. The model accommodates more planning for test than waterfall but makes accommodation of changes harder than other models. The V-Shaped model should be chosen when ample technical resources are available with needed technical expertise. Since, no prototypes are produced, there is a very high risk involved in meeting customer expectations, therefore, confidence of customer should be very high in order for choosing the V-Shaped model approach.
