BACS2163 Software Engineering Tutorial Tu torial 2 1. Incrementa Incrementall model model and Prototyping Prototyping model are two commonly used process models in software projects. i) Discuss a scenario that that is suitable or useful useful to adopt the prototyping prototyping model. Develo Developer perss unsure unsure of the effici efficienc ency y of an algori algorithm thm and unsure unsure of the human/m human/mach achine ine interaction that should take place. ii) Explain the process involved incremental incremental software process model. model. he proces processs which which invol involved ved increm increment ental al softwa software re proces processs model model are commu communic nicati ation! on!  planning! modeling! construction and deployment. deployment. "or the communication will be carry out with the customer to gather re#uirements in detailed and get the feedback. $ext for the  planning process is estimate the time and cost needed and also adjust the project plan. %odelling process is to analysis and design the new system. &onstruction process is start the code and test the prototype. Deployment is delivery the prototype and get feedback and made modification on the prototype to the real system and install at the user side. 'ncremental software process model is to deliver the core product function(s)/feat function(s)/features(s) ures(s) at the first increment/version and deliver the supplementary product function(s)/features(s) in next increment(s)/version(s). iii) hy is the incremental process model considered by many ' professionals to be the best approach to software development in the current software industry* 't is useful because if staff unavailable and also can be planned to manage technical risks example a game can be improve to use joystick or controller in the next increment(s)/version(s) increment(s)/version(s) of software. +. ,ighl ,ighligh ightt the distinct distinct featu feature( re(s) s) and suggest suggest a scenario scenario where where Spiral model is suitable to be adopted. he distinct features of the -piral model is during each iteration through the process steps!  both the technical and management risks are accessed to see if it is still possible to complete the project which its re#uired functionally with acceptable time and cost constraints. he scenario where -piral model is suitable to be adopted is when developing a large projects and also the projects where business goals are unstable but the architecture must be realied well enough to provided high loading and stress ability. . 0ou as an ' manager manager of &oway &oway Direct Direct -elling -elling -dn. hd.! hd.! are re#uired re#uired to develo develop p an online online system which will provide services for its distributors and customers. 2mong other services! the system should allow users to view product and promotion details! register as a distributor! make orders and payments! track order status! check on distributor3s points accumulated and  perform redemption based on points entitlement. entitlement. he distributors and customers of this company basically come from all parts of %alaysia with different education background! level of computer knowledge as well as preference of  language. &urrently! the ' department consists of three staff under your supervision! i.e. one

systems analyst and two programmers. his could be a challenging project as it concerns a new area that your team has not ventured into before. he re#uirements gathered were clear  and could be modularied easily. he top management re#uires that the new online system be completed within three months. 4ecommend! with explanation! an appropriate software process model to complete the  project. 5ustify your recommendation. 0ou may state any relevant assumptions to support your answer.

he appropriate software process model to complete the project is the incremental model because it is useful when the staff unavailable such as the above scenario the ' department consists of three staff only. 'n addition! with the incremental model can help the team to planned to managed the technical risk since this project as it concerns a new area that the team has not ventured into it before. %eanwhile! the incremental model able the team to deliver the core product function(s)/features(s) at the first increment/version and deliver the supplementary product function(s)/features(s) in next increment(s)/version(s) due to completed the new online system within three months.
