Summary: As in any other engineering discipline, software engineering also
has some structured models for software development. This document will provide
you with a generic overview about different software development methodologies
adopted by contemporary software firms. Read on to know more about the
Software Development Life Cycle (SDLC) in detail.

Curtain Raiser
Like any other set of engineering products, software products are also
oriented towards the customer. It is either market driven or it drives
the market. Customer Satisfaction was the buzzword of the 80's.
Customer Delight
is today's buzzword and Customer Ecstasy is the buzzword of the new millennium.
Products that are not customer or user friendly have no place in the market although
they are engineered using the best technology. The interface of the product is
as crucial as the internal technology of the product.

Market Research
A market study is made to identify a potential customer's need. This process is
also known as market research. Here, the already existing need and the possible
and potential needs that are available in a segment of the society are studied
carefully. The market study is done based on a lot of assumptions. Assumptions
are the crucial factors in the development or inception of a product's development.
Unrealistic assumptions can cause a nosedive in the entire venture.
Though assumptions are abstract, there should be a move to develop tangible
assumptions to come up with a successful product.

Market Research：市場調査
identify a potential customer's need：潜在顧客のニーズを確認する
assumption：仮定
crucial factors：重要要素
inception of：・・・の発端
nosedive：暴落
unrealistic assumptions：非現実的な発想
tangible assumptions：有形（非抽象）発想
come up with：思いつく
Research and Development
Once the Market Research is carried out, the customer's need is given to
the Research & Development division (R&D) to conceptualize a cost-effective
that could potentially solve the customer's needs in a manner that is better
than the one adopted by the competitors at present. Once the conceptual system
is developed and tested in a hypothetical environment, the development team
takes control of it. The development team adopts one of the software development
methodologies that is given below, develops the proposed system,
and gives it to the customer.
The Sales & Marketing division starts selling the software to the available
customers and simultaneously works to develop a niche segment that could potentially
buy the software. In addition, the division also passes the feedback from the
customers to the developers and the R&D division to make possible value additions
to the product.
While developing a software, the company outsources the non-core activities
to other companies who specialize in those activities. This accelerates the
software development process largely. Some companies work on tie-ups to bring out
a highly matured product in a short period.
