Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping Also, the spiral model can be considered as supporting the evolutionary model – the iterations along the spiral can be considered as evolutionary levels through which the complete system is built. a) Doesn’t work well for smaller projects b) High amount of risk analysis c) Strong approval and documentation control d) None of these Answer:A. 12. As we learn this model it evolves accordingly. Summary 3. ________________ is a special constituent of chlorophyll without which photosynthesis is not possible ? Unit of surface tension in S.I. hs.src = ('//s10.histats.com/js15_as.js'); Identify the disadvantage of Spiral Model. Your email address will not be published. Answer: a Explanation: All other options are the advantages of Spiral Model. _Hasync.push(['Histats.track_hits', '']); Spiral model was first introduced by Barry Boehm in 1986 and since then it has been one of the most preferred SDLC models for long-term and high-risk projects. Identify the disadvantage of Spiral Model. Advantages: Work process is very important; It is more important to changes that software development generally entails. Development can be broken down into smaller parts, and risk areas can be developed earlier, which helps to manage risks better. Moreover, Spiral model has the ability to make any software testing project transparent. Required fields are marked *. One originating _________________? Good for large and mission-critical projects. Identify the disadvantage of the Spiral Model. Advantages of Spiral Model: Software is produced early in the software life cycle. Strong approval and documentation control. The Spiral Model 1. 2) Project monitoring is very easy and effective. The strain produced in the two wires will be in the ratio of__________________? The following model is a reflection of the Spiral Model, listing the actions in each stage. (C) Strong approval and documentation control (X) Because of the prototype development and risk analysis in each phase, it is very expensive and time taking. Additional Functionality can be added at a later date. b) High amount of risk analysis. So the discipline of change and the extent of taking change requests are very important to develop and deploy the product successfully. (adsbygoogle = window.adsbygoogle || []).push({}); TodayMCQs Software engineers can work on the project earlier; Disadvantages Customized High Software Engineering Objective type Questions and Answers. It is a combination of waterfall model and iterative model. Summary 3. Answer: a Explanation: All other options are the advantages of Spiral Model. This model is best used for large projects which involves continuous enhancements. Waterfall model was also used in banking, healthcare, control system for nuclear facilities, space shuttles etc. The spiral model uses the approach of Prototyping Model by building a prototype at the start of each phase as a risk handling technique. PLEASE COMMENT BELOW WITH CORRECT ANSWER AND ITS DETAIL EXPLANATION. The majority charge carriers in p-type silicon are______________________? Also, the spiral model can be considered as supporting the evolutionary model – the iterations along the spiral can be considered as evolutionary levels through which the complete system is built. var hs = document.createElement('script'); hs.type = 'text/javascript'; hs.async = true; It is a combination of waterfall model and iterative model.

Planning phase Risk analysis phase Engineering phase Evaluation phase. })(); Identify the disadvantage of Spiral Model? d) … a) Doesn't work well for smaller projects. (function() { a. The Spiral Life Cycle Model is a kind of iterative software development model which is normally put into practice in extreme risk projects ("Spiral," n.d.). Disadvantages of Spiral model: In the disadvantages of spiral model includes, it takes very strict management to complete such products and there is a risk of running the spiral in indefinite loop. Doesn’t work well for smaller projects High amount of risk analysis Strong approval and documentation control Additional Functionality can be added at a later date. The spiral model is a risk-driven software development process model. Your email address will not be published. (A) Doesn’t work well for smaller projects () This blog will discuss this prodigious and widely used SDL model in detail. Spiral model is a combination of sequential and prototype model. As we learn this model it evolves accordingly. Force between the molecules of the same substance is called ______________________ force? Disadvantages of Spiral model: Spiral may go infinitely. In a few words, Spiral Model can be characterized by repeatedly iterating a set of elemental development processes and eliminating risk, so it is actively being reduced.To understand how you can get your goals using Spiral Model, let’s take a look at this diagram:As you can see, Spiral Model consists of four main software development life cycle phases. A software project repeatedly passes through these phases in iterations called Spirals. Overview • The “Spiral Model” is a model that represents one method as to how software can be developed. Software Processes, Models & Software Development. Spiral Model design and flow- The spiral model has four phases. Overview 4. Overview • The “Spiral Model” is a model that represents one method as to how software can be developed. The goal of this stage is the detailed definition of the system requirements. Advantages 4. 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 date - 829737 Project deadlines can be missedsince the number of phases is unknown in the beginning and frequent prototyping and risk analysis can make things worse. 1 Answer to Identify the disadvantage of Spiral Model. Doesn’t work well for smaller projects High amount of risk analysis Strong approval and documentation control Additional Functionality can be added at a later date. The spiral model is a risk-driven software development process model. _Hasync.push(['Histats.start', '1,3947665,4,0,0,0,00010000']); These are some main points which explain the project management life cycle model’s advantages and disadvantages. The spiral model is a combination of waterfall, incremental, iterative and prototype model. Details 3. Advantages and disadvantages of spiral model. (D) Additional Functionality can be added at a later date (X), Answers; Doesn’t work well for smaller projects, Your email address will not be published. High amount of risk analysis: c. Strong approval and documentation control: d. Additional Functionality can be added at a … 1. Two wires of the same radius & material having length in the ratio of 1 : 2 are stretched by the same force. Planning Phase: Requirements are gathered and analysis. 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 date - 829737 Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product. While one is stuck between the waterfall model vs spiral model debate, it is best to evaluate the software that is being developed and then decide the right approach. 8. Coating thickness in case of galvanising of steel sheet generally corresponds to the deposition of _______________ gms of zinc per m2 of steel strip ? Development phases can be determined by the project manager, according to the complexity of the project. It is costly for smaller projects. What is Spiral model? A. Doesn’t work well for smaller projects B. Each loop in the spiral represents _____ of the software process in Boehm’s spiral model. Identify the disadvantage of Spiral Model.
