Comfort Quilts LimitedIntroductionComfort Quilts Limited is a business unit that is based out of Sydney, Australia and it operateswith the aid of a website. The business organization sells eiderdowns to retail stores andwholesale outlets. The business is owned by Alison Williams and is being expanded at a rapidscale. A large number of part time and full time employees are working in the organization forthe execution of business processes and activities. When the business was set-up, there werelimited products that were manufactured by the company and also the customer base was limited.However, the expansion of business led to the introduction of many new services and operations.The existing systems cannot handle the new processes and operations that have now beenincluded. This is because of the reason that the legacy systems are based upon the initial set ofbusiness activities.It has been proposed that an enhanced information system shall be developed and implementedin the organization. This information system will provide enhanced capabilities and abilities tothe company so that the existing issues can be avoided and prevented. System Development – Adaptive Approach The information system that has been proposed for the company shall be developed using theadvanced measures and methodologies. There are various approaches that can be used for thedevelopment of the information system. There are two categories of system development approach that can be used. One approach is thepredictive approach for system development. As per this approach, the steps and measures thatare followed are pre-determined. The set pattern is followed in the processes that come under thepredictive approach for system development. The other approach is adaptive approach for systemdevelopment. The methodologies that come under adaptive approach are ad-hoc and value basedin nature. The specifications and requirements of a particular project determine the approach andthe set of steps that shall be followed under the adaptive approach. There is no set pattern thathas been defined under the adaptive methodologies; however, there are a set of pro-activeguidelines that are specified (Pope-Ruark, 2012). 3

On the basis of the specifications of the information system that needs to bedeveloped for Comfort Quilts Limited, the adaptive approach shall be used and implemented. There are a number of adaptive methodologies that can be implemented. One of such adaptiveapproaches is SCRUM methodology for system development. The methodology is based uponthe agile framework and processes. This SCRUM methodology has the capability for theefficient management of scope along with handling of complex processes. The other adaptive approach that can be applied is Extreme Programming (XP). The set ofprocesses that come under XP methodology are ad-hoc and value based. There are a set of corevalues and methods that are linked along with approach. The set of the core values includecommunication activities, feedback processes along with courage and simplicity. Another adaptive approach that can be used and applied is Unified Process (UP). Ad-hoc manneris used in this approach and methodology which includes the adaptive steps and guidelines. As per the specifications associated with the information system for Comfort Quilts Limited, theapproach that has been recommended is SCRUM methodology. SCRUM Methodology for System Development SCRUM methodology is based upon the agile framework and processes. This SCRUMmethodology has the capability for the efficient management of scope along with handling ofcomplex processes.This particular adaptive methodology is ad-hoc and value based in nature and there is no pre-defined process that is applied in this case. The specifications and requirements of a particularproject determine the approach and the set of steps that shall be followed under the adaptiveapproach. There is no set pattern that has been defined under the adaptive methodologies;however, there are a set of pro-active guidelines that are specified (Pathak, Pateriya and Pal,2012). In this adaptive approach, the first step that is involved is the analysis of the specifications andrequirements of the project. The requirements are classified in different categories, such as,functional and non-functional requirements and user specifications. The second step includes the4
