This is an ad-hoc methodology that does not have a fixed process or a predefined path. However,
there are certain activities that have been defined that make it possible to carry out the project
tasks and activities (Pathak, Pateriya and Pal, 2012).
The requirements, specification and the factors that are associated with the project are analyzed
and the product backlog is created by the project owner which can be termed as a wishlist. The
entire project is covered and carried out in a series of iterations and these iterations are called
sprints. The entire set of product backlog is sub-divided in different parts and every sprint
accomplishes one sub-division of the entire backlog.
One sprint lasts for a maximum of four weeks and can range in between two to four weeks.
There is also a daily meeting that is carried out in which the activities for a day are planned. The
issues and conflicts associated with the project are also discussed in this meeting. It becomes the
responsibility of the SCRUM Master to make sure that all the project activities are being carried
out as per the project estimates and specifications. A sprint review is carried out at the end of the
sprint and the team then focuses upon the next sprint that needs to be covered (Mahnic and
Zabkar, 2012).
In this manner, the end product is created as an outcome.
Benefits of the SCRUM Methodology
In case of Comfort Quilts Limited, the SCRUM methodology has been selected and
recommended as it will be the most suitable methodology on the basis of the requirements and
specifications. This methodology will offer the following advantages and benefits.
 The processes and business operations that will be carried out in terms of the supplier
information management and applications, report generation and extraction etc will be
carried out with much ease leading to higher productivity of the business organization
(Kaur and Bansal, 2017).
 There may be many changes that may come up in terms of the requirements and
specifications. These changes may be done to the technology that is used or customer
relationship management system, supplier requirements, reporting requirements and
likewise. SCRUM methodology will make it possible to handle these changes without

any need to carry out massive re-works and changes in the system being followed
(Azanha et al., 2017).
 Every sprint that will be carried out in the project will be reviewed by the internal
stakeholders, external stakeholders including the end-users. In this manner, the specific
areas of improvements will be highlighted and the recommended changes will be covered
in the next sprint. In this manner, the end product will be in accordance with the
expectations of the end users.
 The employees of Comfort Quilts Limited will have an integrated platform and the
availability of the same will be possible quickly and as per the promised schedule. This
will lead to the enhancement of the productivity and satisfaction levels of the employees
(Moe, Dingsoyr and Dyba, 2010).
 The information system that will be developed for Comfort Quilts Limited will be
flexible and scalable in nature. This will make sure that compatibility of the system with
other technological and automated systems will be easy to make and ensure (Machado,
Pinheiro and Tamanini, 2014).
 The quality of the business processes and operations will also improve which will lead to
the increase in the revenues and sales that will be earned by the organization over a
period of time.
Apart from the above benefits, SCRUM methodology will also make it possible to keep the data
and information secure and protected at all times. The security and privacy of the information
will be possible and it will be ensured (Cervone, 2011).
