SYSTEM
REQUIRMENT SPECIFICATIONS
OBJECTIVE:
q
Transport
Plus project deals the welfare of its employees by providing transportation for
the employees to attend their duties in time.
q
Several
employees wish to utilize the bus or cab services provided by the company.
q
Naturally
the company employees need a system to allot the buses and cabs oversee the
transportation.
Existing System:
Now a
days every company needs to see the welfare of its employees by providing
transportation for the employees to attend their duties successfully. Many
employees are facing problem while attending to the office, many MNC companies
are providing transport facility to their employees by arranging their own
vehicles and sometimes taking support from third part transport systems also.
When several employees wish to utilize the bus services provided by the
company, naturally the company employees need a system to allot the buses and
oversee the transportation. Transport Plus is software that quenches this need.
Disadvantages:
- It is
difficult to track the occupancy.
- More
manual hours need to generate required reports
- It is
tedious to track the details of cabs provided by third party.
- There
is no possibility to track the approvals of requests.
- No
co-ordination between various departments.
Proposed System:
Proposed
system is a software application which avoids more manual hours that need to
spend in record keeping and generating reports. This application keeps the data
in a centralized way which is available to all the users simultaneously. It is
very easy to manage historical data in database. No specific training is
required for the employees to use this application. They can easily use the
tool that decreases manual hours spending for normal things and hence increases
the performance.
Advantages:
- Easy
to process requests
- Can
generate required reports easily
- Easy
to manage historical data in a secure manner
- Centralized
database helps in avoiding conflicts
- Easy
to use GUI that does not requires specific training.
- Implementation
of approval process is very easy
- Occupancy
tracking helps in decision making
Modules Description:

SCOPE
OF THE PROJECT
This Document plays a vital role in
the development life cycle (SDLC) as it describes the complete requirement of
the system. It is meant for use by the developers and will be the basic during
testing phase. Any changes made to the requirements in the future will have to
go through formal change approval process.
OOAD MODEL was being chosen because
all requirements were known beforehand and the objective of our software
development is the computerization/automation of an already existing manual
working system.
Fig 2.2: SDLC Model
The developer is responsible for:
·
Developing
the system, which meets the SRS and solving all the requirements of the system?
·
Demonstrating
the system and installing the system at client's location after the acceptance
testing is successful.
·
Submitting
the required user manual describing the system interfaces to work on it and
also the documents of the system.
·
Conducting
any user training that might be needed for using the system.
·
Maintaining
the system for a period of one year after installation.
INPUT DESIGN
Input design is a part of overall
system design. The main objective during
the input design is as given below:
·
To
produce a cost-effective method of input.
·
To
achive the highest possible level of accuracy.
·
To
ensure that the input is acceptable and understood by the user.
INPUT
STAGES:
The main input stages can be listed
as below:
·
Data
recording
·
Data
transcription
·
Data
conversion
·
Data
verification
·
Data
control
·
Data
transmission
·
Data
validation
·
Data
correction
INPUT
TYPES:
It is necessary to determine the
various types of inputs. Inputs can be
categorized as follows:
·
External
inputs, which are prime inputs for the system.
·
Internal
inputs, which are user communications with the system.
·
Operational,
which are computer department’s communications to the system?
·
Interactive,
which are inputs entered during a dialogue.
INPUT
MEDIA:
At this stage choice has to be made
about the input media. To conclude about
the input media consideration has to be given to;
·
Type
of input
·
Flexibility
of format
·
Speed
·
Accuracy
·
Verification
methods
·
Rejection
rates
·
Ease
of correction
·
Storage
and handling requirements
·
Security
·
Easy
to use
·
Portabilility
Keeping in view the above
description of the input types and input media, it can be said that most of the
inputs are of the form of internal and interactive. As
Input data is to be the directly
keyed in by the user, the keyboard can be considered to be the most suitable
input device.
OUTPUT DESIGN
Outputs from computer systems are
required primarily to communicate the results of processing to users. They are
also used to provide a permanent copy of the results for later consultation.
The various types of outputs in general are:
- External
Outputs, whose destination is outside the organization.
- Internal
Outputs whose destination is with in organization and they are the
§
User’s
main interface with the computer.
- Operational
outputs whose use is purely with in the computer department.
- Interface
outputs, which involve the user in communicating directly with
OUTPUT DEFINITION
The outputs should be
defined in terms of the following points:
§
Type
of the output
§
Content
of the output
§
Format
of the output
§
Location
of the output
§
Frequency
of the output
§
Volume
of the output
§
Sequence
of the output
It is not always desirable to print
or display data as it is held on a computer. It should be decided as which form
of the output is the most suitable.
For Example
·
Will
decimal points need to be inserted
·
Should
leading zeros be suppressed.
OUTPUT MEDIA:
In the next stage it is to be
decided that which medium is the most appropriate for the output. The main
considerations when deciding about the output media are:
- The
suitability for the device to the particular application.
- The
need for a hard copy.
- The
response time required.
- The
location of the users
- The
software and hardware available.
Keeping in view the above
description the project is to have outputs mainly coming under the category of
internal outputs. The main outputs desired according to the requirement
specification are:
The outputs were needed to be
generated as a hot copy and as well as queries to be viewed on the screen. Keeping in view these outputs, the format for
the output is taken from the outputs, which are currently being obtained after
manual processing. The standard printer
is to be used as output media for hard copies.

PERFORMANCE
REQUIREMENTS:
Performance is measured in terms of
the output provided by the application. Requirement specification plays an
important part in the analysis of a system. Only when the requirement
specifications are properly given, it is possible to design a system, which will
fit into required environment. It rests largely in the part of the users of the
existing system to give the requirement specifications because they are the
people who finally use the system. This
is because the requirements have to be known during the initial stages so that
the system can be designed according to those requirements. It is very difficult to change the system
once it has been designed and on the other hand designing a system, which does
not cater to the requirements of the user, is of no use.
The requirement specification for
any system can be broadly stated as given below:
·
The
system should be able to interface with the existing system
·
The
system should be accurate
·
The
system should be better than the existing system
The existing system is completely
dependent on the user to perform all the duties.
FEASIBILITY REPORT
Preliminary investigation examine
project feasibility, the likelihood the system will be useful to the
organization. The main objective of the feasibility study is to test the
Technical, Operational and Economical feasibility for adding new modules and
debugging old running system. All system is feasible if they are unlimited
resources and infinite time. There are aspects in the feasibility study portion
of the preliminary investigation:
- Technical
Feasibility
- Operation
Feasibility
- Economical
Feasibility
Technical Feasibility
The technical issue usually raised
during the feasibility stage of the investigation includes the following:
- Does
the necessary technology exist to do what is suggested?
- Do
the proposed equipments have the technical capacity to hold the data
required to use the new system?
- Will
the proposed system provide adequate response to inquiries, regardless of
the number or location of users?
- Can
the system be upgraded if developed?
- Are
there technical guarantees of accuracy, reliability, ease of access and
data security?
Earlier no system existed to cater
to the needs of ‘Secure Infrastructure Implementation System’. The current
system developed is technically feasible. It is a web based user interface for
audit workflow at NIC-CSD. Thus it provides an easy access to the users. The
database’s purpose is to create, establish and maintain a workflow among
various entities in order to facilitate all concerned users in their various
capacities or roles. Permission to the users would be granted based on the
roles specified. Therefore, it provides the technical guarantee of accuracy,
reliability and security. The software and hard requirements for the
development of this project are not many and are already available in-house at
NIC or are available as free as open source. The work for the project is done
with the current equipment and existing software technology. Necessary
bandwidth exists for providing a fast feedback to the users irrespective of the
number of users using the system.
Operational Feasibility
Proposed projects are beneficial
only if they can be turned out into information system. That will meet the
organization’s operating requirements. Operational feasibility aspects of the
project are to be taken as an important part of the project implementation.
Some of the important issues raised are to test the operational feasibility of
a project includes the following: -
·
Is
there sufficient support for the management from the users?
·
Will
the system be used and work properly if it is being developed and implemented?
·
Will
there be any resistance from the user that will undermine the possible
application benefits?
This system is targeted to be in
accordance with the above-mentioned issues. Beforehand, the management issues
and user requirements have been taken into consideration. So there is no
question of resistance from the users that can undermine the possible
application benefits.
The well-planned design would ensure
the optimal utilization of the computer resources and would help in the
improvement of performance status.
Economic Feasibility
A system can be developed
technically and that will be used if installed must still be a good investment
for the organization. In the economical feasibility, the development cost in
creating the system is evaluated against the ultimate benefit derived from the
new systems. Financial benefits must equal or exceed the costs. The system is
economically feasible. It does not require any addition hardware or software.
Since the interface for this system is developed using the existing resources
and technologies available at NIC, There is nominal expenditure and economical
feasibility for certain.
