54.	If you were a lead developer of a software company and you are asked to submit a project/product within a stipulated time-frame with no cost barriers, which model would you select?(a) Waterfall(b) Spiral(c) RAD(d) IncrementalThis question was addressed to me in an internship interview.The above asked question is from Selection of a Life Cycle Model in division Software Processes, Models and Agile Software Development of Software Engineering
Answer» The correct CHOICE is (c) RAD To explain I would SAY: RAD model is INAPPLICABLE to DEVELOP cheaper products/software/projects as the cost of modeling, hiring highly skilled developers/designers and automated code generation is very high.But here the cost is not an issue, so one can select this model as it reduces development TIME.

55.	Which of the following life cycle model can be chosen if the development team has less experience on similar projects?(a) Spiral(b) Waterfall(c) RAD(d) Iterative Enhancement ModelThis question was addressed to me by my college director while I was bunking the class.This intriguing question originated from Selection of a Life Cycle Model in portion Software Processes, Models and Agile Software Development of Software Engineering
Answer» CORRECT CHOICE is (a) Spiral Explanation: Relying on risk assessment/analysis provides more flexibility than required for MANY applications which overcomes the CRITERIA of less experienced developers.

56.	Which two models doesn’t allow defining requirements early in the cycle?(a) Waterfall & RAD(b) Prototyping & Spiral(c) Prototyping & RAD(d) Waterfall & SpiralThe question was posed to me by my school teacher while I was bunking the class.My enquiry is from Selection of a Life Cycle Model in portion Software Processes, Models and Agile Software Development of Software Engineering
Answer» Correct option is (B) Prototyping & Spiral The explanation: Prototyping Model starts with a REQUIREMENTS analysis phase including techniques like FAST, QFD, Brainstorming.In case of Spiral model the first phase involves ACTIVITIES RELATED to customer communication like determining objectives.

57.	Selection of a model is based on(a) Requirements(b) Development team & Users(c) Project type and associated risk(d) All of the mentionedThis question was addressed to me during an online exam.This question is from Selection of a Life Cycle Model topic in chapter Software Processes, Models and Agile Software Development of Software Engineering
Answer» Right ANSWER is (d) All of the mentioned The best explanation: Each MODEL has to have some REQUIREMENTS, a team of DEVELOPERS, users and the risk INVOLVED in developing a project.

58.	Spiral Model has user involvement in all its phases.(a) True(b) FalseThis question was posed to me by my college director while I was bunking the class.My question comes from Evolutionary Software Process Models in portion Software Processes, Models and Agile Software Development of Software Engineering
Answer» CORRECT option is (b) False To explain I would SAY: NONE.

59.	If you were to create client/server applications, which model would you go for?(a) WINWIN Spiral Model(b) Spiral Model(c) Concurrent Model(d) Incremental ModelI have been asked this question in quiz.My question is based upon Evolutionary Software Process Models topic in chapter Software Processes, Models and Agile Software Development of Software Engineering
Answer» Right option is (C) Concurrent Model Explanation: When applied to client/server APPLICATIONS, the concurrent PROCESS model DEFINES activities in two dimensions: a system dimension and a component dimension.Thus Concurrency is achieved by system and component activities occurring simultaneously and can be modeled using the state-oriented APPROACH.

60.	How is Incremental Model different from Spiral Model?(a) Progress can be measured for Incremental Model(b) Changing requirements can be accommodated in Incremental Model(c) Users can see the system early in Incremental Model(d) All of the mentionedThis question was posed to me in quiz.Enquiry is from Evolutionary Software Process Models topic in portion Software Processes, Models and Agile Software Development of Software Engineering
Answer» Correct ANSWER is (a) PROGRESS can be MEASURED for INCREMENTAL Model Easiest EXPLANATION: None.

61.	Identify the disadvantage of Spiral Model.(a) Doesn’t work well for smaller projects(b) High amount of risk analysis(c) Strong approval and documentation control(d) Additional Functionality can be added at a later dateI have been asked this question in an interview for job.My query is from Evolutionary Software Process Models in portion Software Processes, Models and Agile Software Development of Software Engineering
Answer» Correct OPTION is (a) Doesn’t work well for smaller projects To explain I would say: All other options are the advantages of SPIRAL Model.

62.	How is WINWIN Spiral Model different from Spiral Model?(a) It defines tasks required to define resources, timelines, and other project related information(b) It defines a set of negotiation activities at the beginning of each pass around the spiral(c) It defines tasks required to assess both technical and management risks(d) It defines tasks required to construct, test, install, and provide user supportThis question was posed to me during an interview for a job.I want to ask this question from Evolutionary Software Process Models in chapter Software Processes, Models and Agile Software Development of Software Engineering
Answer» The correct CHOICE is (b) It defines a set of NEGOTIATION activities at the BEGINNING of each PASS around the spiral The explanation: EXCEPT option “b” all other tasks/activities are present in Spiral Model as well.
