While nowadays with the help of new technology and proper analysis and design, everyone basin do banking transactions easily and faster.Ob jectives 1) To determine specific needs of system.2) Discuss approaches and tasks of system. 3) Evaluate tools and techniques. 4) Use reserve methods and techniques to design software.Q2. Choose three tooth roots of software. Describe the sources and explain why a project might use each source.Answer The three sources of software areInformation Technology Services Firms,Cloud Computing,open-source Software.Information Technology Services FirmsWhen a companion needs information system but does non have enough resources or expertise to develop system on its own and not suitable for off-the-shelf system, Information Technology Service Firms help to develop customized information system.IT help firms helps in ontogenesis, hosting and course applications.Firm consultants use many of the same processes, methods, tools and techniques that companies use to develop in-house systems.The cases of such IT firms are IBM, HP, Accenture, Wipro, Infosys and moreREASONS TO take aim Informat ion Technology service Firms Latest technology can be use through outsourcing company to IT service firms.Internal staff of company may have limited resources available with them while IT service staff can have many multiple resources available which increases Productivity as well as Flexibility.Cloud ComputingCloud Computing refers to provision of applications where software is license and maintain by leash party.Customers can use software through virtual private networks or Internet.Most popular example of sully computing is Google Apps and Microsoft.Helps in maintaining hardware and software systems more effectively.Data can be hark back easily through just setting connections to Internet.REASONS TO CHOOSE Cloud ComputingCost structure of cloud computing is more flexible than traditional methods.Accessing speed of software can be increase.Once storing selective information/information on cloud server, we can access data from anywhere and at any time.open-source SoftwareThe sof tware in which source code is freely available is likely to be termed as OPEN-SOURCE software.Source code of open-source software can be easily modify by anyone.Such softwares are developed and maintain by group of people.REASONS TO CHOOSE easy-Source SoftwareOpen source software can be easily customize as per user requirement.When company faces be issues in arranging software, Open-Source Software is best option to take.Best example of open source software is Linux and Firewall.Q3. Explain in your own words how you would convince your client to taking on custom software discipline vs. consider purchasing an off-the-shelf software solution.Answer Custom Software festering The software, which is design and develop for some specific purpose for user or company. off-the-rack Software They are the software, which can be purchase and are ready to use for public.E.g. Microsoft Office.Basically, it is a Build or steal choice for organization (whether to build custom software or to pur chase off-the shelf software). No doubt, off-the-rack software are initially good in saving time and money but after on they are quite difficult to manage and customize as they are bound with their loaded features while on other hand Custom Software Development requires high cost for the development but at the same time they are more flexible in compare to off-the-shelf softwares as Custom Softwares can be transform as per changing requirements of business or client. many another(prenominal) times, it happens that we have to pay for the features, which are of no use to client or firm in Off-the-shelf software, so instead of paying money for unwanted features it is better to invest that amount in developing Custom Software.Hence, Custom Software is long-term benefit while Off-The-Shelf is short-term benefit.References Textbook (Essential of System Analysis and Design).
