INTRODUCTION TO SYSTEM DESIGN
1. Introduction
The Mexican restaurant franchise Picoso is planning to upgrade their system of web
based food-ordering services to a mobile-based application. This is in addition to the
incorporation of a home delivery system. Development of a mobile application will therefore
make the process of food ordering even easier. The report discusses the different benefits the
mobile application over the existing web based system. The work-break down structure of this
project is illustrated in this report, that shows the different phases and activities of the front
end development of the mobile application of Picoso franchise. The application is to be
developed in house and the report features and recommends some features, addition of which
in the application will enhance its different functionalities (McWherter & Gowell, 2012). The
detailed structure and the activities of the Picoso app development are elaborated below-
2. The advantages or benefits of mobile application to the web based system
Mobile Applications are more widely used nowadays in comparison to the web based
ordering system as it is more convenient for people to use a mobile application. Examples of
business that have been successful on using the different applications include Starbucks,
Dominos USA and so on. This is because mobile application enhances the interaction between
the service provider and the customers by means of a well-designed and interactive interface.
Use of mobile apps have been a tremendous success in the field of business as many researches
proves. The location based apps enhances the customers’ experience and it becomes easier for
the service provider to track down the customers or target the customers of a specific area.
Picoso is planning to incorporate home delivery services along with their normal services and

44
INTRODUCTION TO SYSTEM DESIGN
therefore geo-based application will definitely be a great help in providing valued services to
the customers. Designing a simple and interactive interface should be a topmost priority for
Picoso while developing the front end of the mobile application. Therefore, use of mobile
application may help the organization in increasing the scope of their business (Bharadwaj, et
al., 2013). Furthermore, developing a custom mobile application keeping in mind the business
processes improves the efficiency of the application. Starbucks, which is the largest coffee chain
in the world, offers mobile application for iPhone that makes the process of ordering of foods
and drinks easier. Payment through mobile application allows the customers to order food
without waiting in line (Wen, et al., 2014). Therefore, it can be said that the mobile services
have revolutionized the food retailing services over the years and it will definitely benefit Picoso
with their home delivery services. Successful mobile application development and its
implementation require proper understanding of the nature of services to be provided and the
probable amount of target customers (Saarijarvi, et al., 2014). Another trendsetter of mobile
marketing is the mobile application offered by the Dominos USA. It offers pizza ordering
application for both android and iPhone. The application proved to be a huge success for the
organization with more than 1000000 downloads from play store and apple store and with
maximum five star ratings. Both the application allows its users or customer in ordering food
and tracking down the order quite effectively and hence, it is a success. Researches proves that,
nowadays people prefer mobile application over web based system and therefore having a
mobile application service adds to the business needs (Zhao & Balague, 2015). Evidences shows
that majority of the Smartphone users uses or downloads at least one branded application and
therefore, mobile application can offer a useful platform of expanding the business further and

55
INTRODUCTION TO SYSTEM DESIGN
reaching a wider audience (Kim, et al., 2013). The increasing use of Smartphone makes it
obvious that the use of a mobile application would be a profitable decision on a business
perspective for Picoso. A user friendly app development service will enable better customer
satisfaction, which in turn will the help franchise to grow even bigger. Furthermore, the web
based system is more complex than a mobile application and ordering food is difficult in a web
based system than in a mobile application. The in house application development will provide
additional benefits of app customization according to the services offered and customers’
preferences.

4. Recommendations for Picoso
One of the major benefits of developing an application in house, other than out sourcing
is that, application can be easily customized if required even during the implementation phase
of the project management. The recommendations for Picoso in development of the front end
of the application for the restaurant is listed below-

99
INTRODUCTION TO SYSTEM DESIGN
1. The application can be successful if it is able to recommend food options according to
the customer’s preferences. This would further help in increase the customers’ satisfaction. The
concept of data mining would be beneficial for knowing about the customer’s preferences.
2. The simpler and interactive the user interface is, more it will attract customers in
using it. Therefore, an essential part of the application development is the building a simple and
interactive user interface.
3. The payment option in the application should include a secure gateway. The
application furthermore should be easily customizable. This will help the customers in using the
application without any hassle.
5. Conclusion
Therefore, from the above discussion it can be concluded that Picoso’s idea of
implementing a mobile application would be beneficial from a business perspective. This is
because, with the advent of mobile technology and use of smartphones, the rate of use of
mobile application has also increased over the years. Different researches and evidences prove
that, majority of the people prefer to use mobile application instead of online web based
ordering system. The report discusses in brief the benefits of implementing a mobile
application. The work breakdown structure of the mobile application to be developed is
illustrated in the report as well. This provides an insight of the phases and deliverables of the
project of development and implementation of the front end of the mobile application. The
report further recommends different features that can be included in the mobile application

development. Thus it can be deduced that implementation of this mobile application would be
beneficial for Picoso in expanding their business.
