IS DEVELOPMENT METHODOLOGIES

Executive Summary
An online business application system is a system that will be used in managing the resources of
the restaurant. This application aims at offering provision of services by facilitating and serving
the customers and the restaurant as a whole. This Business information system of Crinitt Venice
will be a process where food is ordered online or through the use of an app. This system is based
on keeping the customers to keep accounts of their frequent ordering. The system will also allow
the company to know the stock in place, used and unused and how low it is? Lastly is that the
application will help the restaurant in generating the financial report monthly, semi-annually and
yearly. A business information system (BIS) consists of the interrelated components that are
known for working collectively in carrying out inputs, process it, outputting, storing and
controlling all the actions in conversion of that data in to information products that are applied
because they support forecasting, controlling, do planning, making of decisions and engagement
in operational activities. In differentiating with IT is that IS deals with how the technology is
applied and managed in contributing to the business.

Objectives of the project
The objective of this report is coming up with a business information system that will help
Crinitt Venice in improving the ways it offer services to its customers. The main idea in
achieving the development is first of all identifying the benefits that will be associated with this
BIS being successful (Baltzan, 2017).The other objective is identifying the stakeholders of the
project and, much more preparing the system requests. Last objective is knowing how to the
system development life cycle in identifying the best methodology of dealing with the IS
development. The problem that need to be achieved in the business information system is the
developing of a system that will automate all the operations of Crinitt Venice. The statement of
the problem is coming up with a system that will generate the reports monthly, annually and
semi-annually and much more a restaurant business application where customers can view
menus and order online without necessarily calling for waiters. Also we need to understand how
the problem will be solved and what are some of the methodologies to be applied in finding the
solution.
Stakeholders
In business information system the stakeholders are the users of the system, developers,
managers and technical staff that support all the functions of Crinitt Venice. The following figure
show how the stake holders interrelate in the restaurant.
On the left side of the diagram it clearly shows the stakeholders involved in the development of
Crinitt Venice’s BIS which has been broadly classified by using different stakeholders (Whitten,
2013).
1. System analyst- this is the person who serve as system facilitator by offering the bridge in
communications gap that may be developed in between the non-technical system users,
the technical designer of the system and the builders.
2. System Owners- these are the holders of who are always interested in cost and benefits of
the system. They come from the management in different ranks. In cases of situations of
large or medium firms the stakeholders here are the middle or the executive managers but
3

for small firms the owners are the middle managers or even taking the title of supervisors.
It’s good to know that the system owners are always interested in the bottom line.
3. The system users here are the people who are concerned with the functionality of the
system as they the ease of use of the system. This users may be the normal clerical
service workers, technical staff, professionals staff, the supervisors or middle managers,
clients/customers, the suppliers, partners who collaborate with Crinitt Venice, normal
employees. This always ease the learning and hence becoming a primary concern as they
get the job to be done.
Figure 1 class work notes on Stakeholders
4. System designers are stakeholders who have interest in the information technology
choices and in the system designing
5. System Builders- are used for constructing the system according to what the system
designer has designed

6. Project managers- this individuals who work tirelessly by working together as a team in
building an information system. The project manager is known for ensuring that the
systems development is on the timeline and work within the budget constraints and with a
quality that is acceptable.
Requirements using Waterfall Method
The software development process is a very major process in every successful project. SDLC is
known for setting all activities, offering the best practices, producing deliverables and
automating tools that the stakeholders applies in developing and maintaining the IS and software
(Dennis, 2012). The general approach of Crinitt Venice will be addressed as shown below.
Figure 2 Waterfall method
Using the general approach of Waterfall
method where we will explain the steps of
achieving the Business application system
for Crinitt Venice restaurant (SISMD,
2015). The process will be as follows.
1. Identifying the Crinitt Venice
restaurant problem
2. Analyzing and defining the problem
experienced by Crinitt Venice
3. Identifying the requirements and the
expectations of Crinitt Venice
(Modernrequirements, 2017).
4. Consider and identifying the
alternative solutions and choosing
the best action (Avison, 2006).
5. Designing the best chosen solution
6. Implementing the best chosen
solution
7. Evaluation of the result
In the case of Crinitt Venice the problem is automating its operations and the analysis we got is
that we want an app that have menus and where the customers can order online, also we have
5

seen that we need a system that will be able to produce or generated reports yearly, semi-
annually and monthly. We have to choose the best solution from that we come up with a system
that will meet the needs of the user and those of the owners (Panchal, 2015).
In achieving all this the above can be shortened in to five main activities as shown below here.
Figure 3 WATERFALL SDLC
Planning and analysis
In planning phase is here we meet with the customers so that we can understand their requirements. At
this stage Crinitt Venice will know the whether the project will be clear, activities which are discrete and
hence work needed to be accomplished within the single project. It’s good to note that if planning is
completed successfully it will help in ensuring the smooth working of all other phases. Lastly is that
planning is used for developing a Baseline project Plan and the Project Scope statement
The analysis phase is very important in documenting all the requirements that are desired for
development of the software. In getting the analysis we can do this in Crinitt Venice by dedicating time
in conducting extensive interviews with all restaurant stakeholders (Gordiyenko, 2014). The analysis will
compose all the structures of the incoming data, then we analyze the data and consider all technical
limitations that may occur on the customer’s side and hence the system analyst has to come up with a
specifications which are ready-to-follow that meets the needs of the clients. When doing the planning
and analysis then we have to consider all the constraints which may hinder the development such as the
timeline and the budget.
System Request Preparation
The system request response is based on the following scenarios and commitments in developing
the BIS for Crinitt Venice restaurant. The following issues in identifying and making the work
being successful in preparation of a system request are described in the table below.

SYSTEM REQUEST FORM
ELEMENT DESCRIPTION EXAMPLES
Project
Sponsor
The first step is identifying the project sponsor
being the individuals who recognizes the needs
of the business and serving as the primary
contacts for the project
In Crinitt Venice this are the system
owner’s stakeholders
Business
need
Identifying the needs of the business is the next
procedure in the plan where to know the
prompting reasons to why Crinitt Venice has
prompted in developing a business information
system. This is known as it will include all the
capabilities and the features the IS will include
in it.
Increase sales
Improve market share
Improve customer service
Improve access to information
Generate reports
Increase competitive advantage
Business
requirements
The other plan is knowing the requirements of
the business and this is simply the capabilities
that the system is having or need to have. Great
emphasis is given on their reason to why it is
required other than what it achieve in real sense.
Provide online access to information
Capture customer demographic
information
Include product search capabilities in
form of menus
Produce management reports
Include online user support
Business
Value
There will be increased in competitive
advantage,
Another benefit is that less will be spent in
employees many staffs
High percentage in increase in sales
Percentage in increase in market share
Special issues
or constraints
This is mostly on the timeline, budget and much
more the unavoidable situations
Govt.-mandated requirements
System needed in time for the
On peak season
Top-level security clearance needed by
project team to work with data.

NB: After completing the System request plan preparation is then submitted to the committee of
Crinitt Venice for approving after considerations.
Budget
The budget is made and designed on the basis of SDLC used (InfoEntrepreneurs, 2018). IN this
case the budget will use the waterfall model in explaining the cost which will be inform of
dollars as shown below. Assuming we are given a budget constraints of about $10000
Activities Duration (Weeks) Cost ($ Dollar)
System Designing One 2000
System developing Three 5000
System Testing one 1500
System Verification and Validation one 1000
Total 9500
Competitive Advantage
Some of the competitive advantage gained by Crinitt Venice will be that they will have an
automated system and hence loss of information and incorrect order and records when dealing
with suppliers will be very minimal and very rare (Eduqas, 2018). The other competitive
advantage will be that the restaurant will be updated by knowing what the other restaurants are
offering as they will be online and this will help them in adjusting the price for them to be able to
be stable in the economy. Last advantage will be that they will gain more customers as the
growth of technology has incorporated many which has results to many using it even in areas
whey they do online purchasing and delivered at their home.
Possible Effects
Some of the possible effects if the system is implemented will be as follows.
8

 There will be increased number of orders
 There will be accuracy and transparent as the system will be able to cater for all Crinitt
Venice issues.
 The other effect to expect is that there will good and accurate records of the finance
monthly, semi-annually and yearly generated.
 Lastly is that it will reduce work and save the cost of hiring many people as the system
will do some jobs that could have been done manually.
 There will be less paper work.
Conclusion
The idea behind this proposal is understanding the concepts of Business Information technology
and if implemented how it will help Crinitt Venice?
