Stage 2:

Answer 9

Defining Requirements

Question 10

SRS

Answer 10

(Software Requirement
Specification)

Question 10

Once the requirement analysis is done the next step is
to clearly define and document the product
requirements and get them approved by the customer
or the market analysts.

Answer 10

Defining Requirements

Question 11

Stage 3:

Answer 11

Designing the Product Architecture

Question 11

This is done through an SRS (Software Requirement
Specification) document which consists of all the
product requirements to be designed and developed
during the project life cycle.

Answer 11

Defining Requirements

Question 11

• This DDS is reviewed by all the important
  stakeholders and based on various parameters such
  as risk assessment, product robustness, design
  modularity, budget and time constraints, the best
  design approach is selected for the product.

Answer 11

Designing the Product Architecture

Question 12

is the reference for product architects to come out
with the best architecture for the product to be
developed.

Answer 12

SRS

Question 13

Based on the requirements specified in SRS, usually,
more than one design approach for the product
architecture is proposed and documented in a DDS —
Design Document Specification.

Answer 13

Designing the Product Architecture

Question 14

WHAT IS DDS?

Answer 14

Design Document Specification.

Question 15

design approach clearly defines all the architectural modules of the product along with its communication and data flow representation with the external and third-party modules (if any).

Answer 15

Designing the Product Architectur

Question 16

Answer 20

Stage 4: Building or Developing the Product

Question 21

* This stage is usually a subset of all the stages as in the modern SDLC models, the testing activities are mostly involved in all the stages of SDLC.

Answer 21

Stage 5: Testing the Product

Question 21

However, this stage refers to the testing-only stage of the product where product defects are reported, tracked, fixed, and retested until the product reaches the quality standards defined in the SRS.
