Therefore, here,
for those looking for what kind of job to take in software development, we will
check in detail the actual situation of this industry that can be seen from the
process and flow.
Software Development
Company in Thane is a series of processes that develop programs that run on a computer
according to customer needs and release them as products. There are three main
types of deliverable produced by this method.
・ System software
・ Application software
・ Embedded system
With the widespread
use of smartphones and IoT home appliances, software development was considered
an auspicious task compared to when systems were operating only on servers and
personal computers.
What is the flow of software development?
Software Development
Company in Thane generally begins with sales to customers who are thinking about
improving the efficiency of their current operations.
In customer
interviews, which is the next step after sales, we will discuss what they are
having problems with and what they need to do to solve them.
To develop highly
satisfying software, it is indispensable to confirm the operation start time
and budget and analyze other companies' systems in the same industry.
In addition, when
planning and proposing a system based on such information, it is common to make
several corrections while having the customer check the contents.
When you finally
have a plan that you are satisfied with, submit an estimate at that stage, and
if you can agree, it will lead to a software development contract.
Therefore, before
proceeding to the actual development process, it is necessary to cooperate with
sales and system engineers, conduct many hearings, and modify the project's
contents.
What is the software development process?
There are slight
differences in the business flow in the software development process depending
on whether you make a contract or an in-house product. First of all, when
developing on behalf of a customer, the flow is to create a deliverable in the
following six steps.
Requirement definition
Requirement
definition is the work to clarify the work to be systematized and the required
performance based on the planning proposal. To create a requirement definition
document here, it is first necessary to understand the business flow of the
existing system and check the system design document.
At this step, it is
also essential to clarify what kind of work is necessary by defining the
division of roles between the development and customer sides. In the
requirement definition, we will also consider solutions so that the request can
be incorporated into the design.
Design
In the design that
determines the specifications and the overall picture in software development
based on the requirement definition document, it is necessary to consider many
items as follows.
・ Input/output method (database, screen)
·Processing method
・ Test method
·Operation method
・ How to ensure security
・ Maintenance after delivery Maintenance
By the way, in the
development of large-scale software, it is common to divide the functions into systems,
subsystems, and programs in stages and organize them before proceeding with the
design. The contents summarized in the primary design document will be used for
the system's internal design after the development and the customer reviews.
Development
The program is
written in a computer- process able language such as Java or C based on the
specifications and design documents. The choice of language to use depends on
the output device and product characteristics.
Test
There are four
tests to check whether the system works according to the specifications and
design documents.
・ Unit test (verification of program unit)
・ Integration test (verification of multiple
programs)
・ System test (confirmation of the entire system)
・ Operation test (verification using data handled by
customers)
A system or program
that does not work correctly even after testing constantly has a source code
defect (bug) somewhere. At this time, debug again and remove the bug.
In the case of
large-scale software development, where the source code to be verified is
enormous, debugging also takes a lot of time.
Delivery of materials
Software that has
passed the operation test and has been confirmed to operate normally will
finally be delivered to the customer. At this time, the operation manual,
system design document, and program created at the development site will also
be handed over.
For the
first-introduced system, which tends to cause anxiety on the customer's side,
the development company may provide operation explanations such as a series of
operations.
Maintenance
Backing up
important data, checking system operation, and providing support in a failure
are essential tasks for a software development company. For a certain period
until the stable operation, it is necessary to take positive measures against
system malfunctions.
In addition, when
the system is revised, or there is a request from a customer, we may respond to
the addition of functions after delivery.
Process for developing in-house products
On the other hand,
in the case of in-house package development, there is no customer hearing in
general contract development. Therefore, it is a flow to proceed with
requirement definition, design, development, and testing for the contents of
product planning in-house.
This development
has the characteristic that it is easy to get attached to the services and
packages you have created by taking the opportunity to be involved in product
planning.
However, even in
in-house development, it is required to work efficiently within a fixed budget,
so please consider that person-hour management and schedule management are as
important as contract development.
