Analysis and Design Report for Acme
Introduction
The important concerns of Acme’s
system analysis and design are the monitoring of success or failure of the
system. There is a correlation of general system analysis and design best
performances to the system successes. The system analysis project analyzes the
system analysis and design best practices found in existing information system
(IS) literature. The practices studied by IS researchers are compared to the
practices proposed by the IS practitioners. The findings from the study confirm
that many best practices such as
consumer participation, executive management sustenance, clear statement of
requirement, proper planning, realistic expectations and proper planning are
challenging in the society (Dennis
& Roth, 2014.
1. Description of Acme
During the development of the system
design analysis, various organizations use standard steps called the system
development life cycle (SDLC). It is used as a structured and common
methodology for system development. The structure has four stages such as the
planning, analysis, design, implementation, and maintenance. The stages have
various advantages and disadvantages in a way that could be used to fit and
optimize various kinds of projects in Acme.
Size of the organization
The Acme organization is large enough to fit
SDLC model with employees about one million
Acme’s Environment
Analysis
of Acme’s external environment entails the customers, competitors, technology,
and social issues. With regards to customers, Acme has a large base of
customers. For example, at least one quarter a million customers per week visit
Acme. This can be attributable to the low prices with which Wal-Mart offers to
its customers. Wal-Mart also offers a wide variety of merchandise in comparison
to the other retailers (Cummings & Worley, 2004).
Organizational culture
The company has built an
effective communication plan that explaining its objectives as well as
rationale, the period and the cost of not changing. It does the Implement the
communication plan timely and communicates often. The organization also sends
out recurrent progress apprises. Focus the organization’s devotion forward and
create an excitement about the new modifications to the SDLC.
Pros of SDLC
There are various problems facing
the company for its perfect performance or deliverance to Acme. The slow
running of the system at the peak hours during the morning and the afternoon
hours influences the tasks performed by the Acme representatives. The
technology in not up to date since it misses places to insert the email
addresses possessed by many customers since in improves customer service
operations.
Cons of SLDC
There is no immediate record of various
transactions performed at the company and the data about the most recent
transactions, and the previous should be kept in the database. There is
difficulty in the tracking of the customers who are lagging behind in their
payments and it would be perfect if the problems are solved (Dennis & Tegarden, 2015).
There is also the lack of the software tracking the potential customers
purchasing behavior within the company, but the user applies the use of
databases.
There are positive impacts in the
addressing of the problems and the opportunities facing the SLDC. The improvements of the slow running
systems during the peak hours would improve the company output since many
customers would be served at a short time. The improvement of the customer
details insertion system would store all the information about the potential
customers within the company to enable easy tracking.
2. Analysis
The analysis involves the
identification of problems, and the possible recommendations and solutions for
the problems in the Acme. System analysis gathers and interprets fact helping
in the solution of various problems within the company. Problems may be
internal or external created problems, and various companies have employee’s
performing different roles in promoting various positive aspects in their
developments.
Roles of various employees
Customer representative supervisor (user)
The customer representative
supervisor has very many roles to play in the company. He acts as a coach to
the employees to establish suitable goals activities and time lines. Supervisor
delegates and provides ongoing guidance and support to the workers in their
activities.
The supervisor mentors the employees
because they understand the organization and the employee’s jobs better than
the employee. The employees in the company must view the supervisor as a role
model to enhance the progress of the company.
He has the responsibility of advocating
for the Acme company telling the employees about the new policies and schedules
form the management. The company employees may the frustrated by the induction
of new policies to the company but the supervisors help in the clarification.
System analyst IS
System analyst is responsible in the
analysis and designing business systems within organizations. They play a vital
role in understanding the operations of the currently developed systems for
specific objectives. A system analyst is like an architect in the development
of the new systems providing the blue print in the development of the required
system. System analyst is the most important personality in the development of
the system by having the entire knowledge about the system building.
Chief information officer
In Acme Company the chief
information officer helps in the critical interface between the business and
ICT.They combine and understand instructional business needs and perspective of
user requirements. They help in the management and planning of ICT including
policy and practice in the development, planning, and budgeting.
Report on the technical feasibility of the project
The feasibility report is the
measure of how beneficial or practical the development of information system is
to the organization. The technical feasibility is a measure of the practicality
of a specific technical solution and availability of technical recourses and
expertise. In Acme Company, the development of the software to integrate and
mark the customer’s purchasing power enables the tracking of the customer’s
statistics.
Report on the economic feasibility of each project
calculates ROI
Economic feasibility identifies cost
and benefits associated with the system within the, Acme company. The process
in concerned about the calculating future cash flow, while measuring the
financial strength on the company. The economic feasibility enables the
financial analysis and opportunities including the pending risks in the
project.
Calculation of ROI
The return on investment (ROI) is
the calculation measuring the average rate of return earning o the money
invested in the project. It is a simple calculation that divides the project’s
net benefits (total benefit-total cost) by the total cost.
ROI= Total benefits-Total Cost/Total costs
Report on operational feasibility of each project
Operational feasibility measures how
well a solution meets the system requirements to solve issues while taking the
advantage from opportunities discovered during analysis activity. In measures
how the satisfaction of the system requirements related to each activity is
analyzed.
Design
System analysis designs include
steps in examining business situations with the purpose of improving it through
perfect procedure and methods. It involves many types of systems supporting
different types of projects.
Identify specific task involved in the chosen
project and provide a CPM
The system analysis and design
refers to the process of examining a business situation with the intention of
improving procedures and methods. It relates to shaping organizations,
improving performances and achieving objectives for profitability and growth.
System analysis expands on the system and their relationships among subsystems
and their contributions to reaching a specific goal (Lin,
2014). The analysis defines what the system can do while
design show hoe to accomplish the goals and objectives of the project.
CPM of system analysis design is a
critical path method showing the chronological process defining the critical
and non-critical tasks with the intention of preventing possible problems. The
Critical Path Method is good for the projects consisting of many activities
acting in a complicated manner.
Provide the itemized list of money that will be
spent for different aspects of the chosen project
The SLDC company system analysis and
design budgeting should promote the short-and long-term financial viability of
the company. All the budgeting system of the project evaluates the progress
towards the budget balancing during the fiscal year providing tools to
documents to increase or limit expenses and revenues. The company board uses
the budgeting system to influence the decisions affecting the company policies.
Before the project, there is a creation of work breakdown structure,
identification of task patterns and calculating the critical path.
