Question-1: Report
Introduction-Adaptive Methodologies
In today’s world, there are a number of methodologies for adaptive development is available. So
here in this report, the specific agile development methods are used widely which will be useful
for this Free Feet Socks Limited organization in developing their project. The agile software
methods are referred to as the agile techniques at times. Some of the popular agile techniques are
discussed here such as Scrum, extreme programming (XP), and adaptive software development
which would be relevant to project in FFSL (Alkhateeb, et al., 2017). These agile methodologies
will differ in the approaches made to the development of software and the type of management
that is proposed. The agile methods such as Scrum and feature driven-development focus
extensively, on project management in FFSL and its collaboration practices. While the other
agile method that is extreme programming (XP) heavily concentrates on the practices of software
implementation.
1. Adaptive methodology- Scrum
 Description:
For accomplishing the innovative projects Scrum is considered to be the effective agile
framework. The business owner Alan Masters has started this FFSL organization that
used to take all the orderings and selling by him. Later the business has grown and gave
an opportunity for many part-time and full-time employees. This scrum software works
well with the complex, innovative, or new development of products scope of work (Alter,
2016). So the organization can now choose this which would be the best adaptive
methodology as it is looking forward to the further expansion of the company with a new
project. The new project that is undertaken is underwear and home goods such as scented

candles. This methodology is proposed to be effective as it has got the endless
possibilities and the framework of Scrum is deceptively simple.
 Advantages:
The scrum methodology will be allowing the project where the documentation of the
business requirements would be hard to quantify for its successful development. At
present, the FFSL business is having the manual control of stock and the customer
relationship systems which use to work well earlier and they used to manage the accounts
with the shelf accounting system (Dennis, Wixom & Tegarden, 2015). However, now by
this methodology fast moving and the cutting edge developments can be coed quickly
and tested with this method where the accounting mistakes can be rectified easily.
 Disadvantages:
In this firm, the sales people are defined for their own geographical area in selling the
products of FFSL. So the task should be well defined if not the estimating costs of the
project and time might not be accurate. In the stores, the selling of the FFSL goods is not
taken up by more than one sales person (Duan & Yu, 2013). But as a part of the new
project, it is better for the members to work in a team and committed so that it will not
fail otherwise it would not be complete.
2. Adaptive methodology- Extreme programming (XP)
 Description:
Extreme programming (XP) is known to be one of the agile methodologies. By using this
methodology the organization can share all the principles that are involved in their firm
such involvement of customer strongly into the development process of software,
effective communication among the team members and iterative cycles of development.
This company is using the shelf accounting package and email services for
communicating with suppliers and customers (Erturk, 2016). Currently, the use of the
computer in the firm is at a low level. With this methodology, they can get close
interaction with customers and understand their requirements and then the project can be
undertaken as per their needs.

SYSTEM ANALYSIS AND DESIGN
 Advantages:
The biggest advantage with this extreme programming methodology is that it will allow
the FFSL firm in developing their own software by saving costs and time for project
realization. Currently, the orders are taken through phone calls by the representatives and
monitor them till the time they are delivered to the customers which is a tedious process
(Grbovic, 2013). But by this software programming time can be saved and the
representatives can be assured that the products are delivered to the customers on time.
 Disadvantages:
For checking the progress of the orders the representatives will call the head office. It
means that the staff of the headquarters will be handling phone calls from sales people.
However, this can be avoided by designing software for taking the orders and for
knowing the progress. But the big disadvantage is that extreme programming is focused
more of the code rather than on the design (Guruacharya & Hossain, 2017). This might
be an issue because for software applications good design would be extremely important.
3. Adaptive methodology- Feature Driven development
 Description:
For software development being an iterative methodology it is designed in serving the
wide-ranging group of teams that are working on the new project that is based on object-
oriented technology. In the past, the FFSL organization was having the manual systems
for stock management and the customer relationship management, but the manager with
the new purchasing manager and the customer manager are thinking that information
system will be offering improvements significantly to the work processes that are
currently in place. So this type of model would be decent for this company as it is passing
from the phase based method to the approach that is iterative (He & Dey, 2014). This
agile methodology is known as the feature-driven development methodology which is
known to be highly functional and creative enough for dealing with the diverse
complexities.
 Advantages:

SYSTEM ANALYSIS AND DESIGN
Steven Smith the customer manager is expecting the sales people and the representatives
of party plan in ordering the products through online as they are involved in making
sales. So this methodology will do better for them as it helps in moving the newly
developed bigger products with continuous success. The sales people have to check in
online at every retail outlet which is main requirements so that for every visit they make
it gives the idea of whether sales are being made or not. By this, the outcome will be in a
better way. The sales calls of the representative can be tracked (Li, Lee & Lui, 2013).
Some pre-standards are to be set by this software development so that it can be
programmed for the procedures of the company.
 Disadvantages:
This methodology is definitely not suitable for smaller projects and the single developer
which is the company is trying to do. This is because the customer manager of FFSL
Company is willing to make the bigger orders less frequently because he wanted to take
the advantage of the smaller shipping costs for each piece of the merchandise (Mahmoud,
2016). In such case, this is not the appropriate idea as it is dependent highly on the
leading developer which is demanding for the total structure. If at all the company is
taking this software then no written document will be provided.
Recommendations
Agile scrum methodology a project management system that is incremental is based on product
development sprints in two to four weeks. So this would be the best methodology for the FFSL
organization in expanding their company with new products. It has got many benefits such as
better communication with suppliers, customer relationship can be managed efficiently, and
planning for product development can be made effectively. As a result, the expectations of the
company can be met since it will be resulting in increased productivity. The execution will be
faster by implementing with this methodology and the products of high quality that are ideal will
be attracting the customers and the sales will be grown easily (Rosenblatt, 2013). However, it is
adopted by numerous organizations which have experienced the success exponentially through
this system by building progressive iterations of the product.

Re: A plan for the development of the Human -Computer Interaction (HCI)
Dear XXX,
I would like to inform you regarding the improvements in the FFSL Company by introducing
some new effective methodologies. At present, no employees in the FFSL have a strong
command over the computers and its usage for getting their work completed external to the
standard applications. Hence, I am proposing the acceptance of the new system which is my
main concern. So here I would be describing the brief setting of a plan for the development of
the Human-Computer Interaction (HCI).
Description:
HCI which is known as the human-computer interaction can be defined as the study of how
people will be interacting with the computers and to what level the computers have been
developed or not for having a successful interaction with the human beings. There are
substantially many numbers of key corporations and the academic institutions which are taking
up the study of HCI. With some of the exceptions historically, the developers of computer
system did not pay much attention for ease of use of the computer. Today most of the users of
the computer will be arguing that the makers of the computer are not paying enough attention
still in making their products user-friendly. However, the developers of the computer system
might result in the argument that computers are the products that are extremely complex in
designing and making. The demand for the services that are provided by the computer has
always found to be outdriven the ease of use demand.
Plan for HCI for FFSL

SYSTEM ANALYSIS AND DESIGN
The plan for human-computer interaction for FFSL firm has been shown in the following figure.
It includes a number of stages by attaining which the computer system can be developed as per
the requirements of the company in terms of software. It can be made user-friendly by providing
training on the software’s that has been adopted by the company (Valacich, George & Hoffer,
2015). This can make the use of the system by human beings very simple.
The business strategy of FFSL is it has decided to focus mainly on building and implementation
of the application of the customer relationship management and it wants to run a project
separately for the purchasing project. For this, a specific agile methodology can be adopted by
the firm and then all the employees can be trained on the same. Monitoring and reporting of the
application can be made by allowing the sales persons to fill in the application in every store they
visit. The segment roles come into the picture where the applications will be reviewed by the
management team and the applications with mistakes will not be approved. Then the necessary
action is taken by planning were the records of the FFSL will be having all the details of the
customers such as name, number, address, last visited, etc. so that the use of the system by the
sales representatives in the firm will be easy. In the entire population, each area is defined some
particular sales members finding out the gaps in the sales would be easy through the data that is
available. By making use of the current state analysis the use of the system can be made easy for
each of the members in the organization. This can be achieved by making all the processes
online such as placing the order online and monitoring the progress. In order to do so, the sales
team has to first login with the details into the software.
Recommendations
Technology acceptance model can be defined as the theory of the reasoned action taken in the
areas of information systems. It is suggested by this theory that if the FFSL organization can
determine the ease and usefulness of use of the system and the intentions of the individuals in
using the system than it can serve as the mediator for the better productivity of the products. If
the intentions of the users are perceived than it can be learned easily. By making use of one of
the three approaches of technology acceptance model the FFSL can actually extend its attempts
such as by introducing the factors from the models that are related to the products of the firm, by
introducing the factors that are additional or alternative in promoting the productivity of the firm
and by examining the individuals who are interested in knowing the usefulness of the system.

Hence by making use of this technology the company can take a step forward in assessing their
employees and training them in that specific field by making them know the effectiveness of
getting adapted to the system.
