ABC Technologies is an IT company founded in 1996 that employs over 7,000 people. It uses an incremental model of software development where requirements are broken into smaller modules that are developed and tested in cycles. This allows for flexibility and client feedback at each step but has higher total costs than the waterfall model. The spiral model combines iterative development with aspects of the waterfall model, forming a more systematic approach where conceptual designs, risk analysis and client feedback occur in cycles. It is well-suited for large complex projects. Agile development involves self-organizing cross-functional teams collaborating to evolve requirements and solutions.

3. Incremental model
In this model the
requirement is
divided into various
builds
Cycles are divided
up into smaller,
more easily
managed modules

4. Phases in the module

6. Advantages and disadvantages
1. More flexible, easier to test in
smaller builds
2. In this model customer can
respond to each build thus working
closely at each step
3.Lowers initial delivery cost
1.Needs good initial design and
planning
2.Clear understanding of system
requirements is a must for using
this model
3.Total cost is higher than waterfall
model

7. SPIRAL MODEL
It combines iterative development with the aspects of the waterfall
model thus forming a more systematic and controlled model
Identification
Basic requirements are
gathered and system
requirements are broken down
to unit requirements
Various builds are created and
initial coding is done, clients
feedback is required after the POC
development. In the next spiral
actual coding start and builds are
given a version no. and then sent
for client’s feedback
Conceptual designs are made,
design docs are created and
modules are designed and
discussed with clients
It includes
-Monitoring technical feasibility
-Risk identification and
management(schedule slippage
and cost overrun)
Evaluation
and Risk
Analysis
Design
Construct or
Build

8. Spiral model

9. Spiral Vs Incremental
• Very flexible model and the development manager can decide the
phases according to the complexity of the work and resources skill
• Estimates (i.e. budget, schedule, etc.) get realistic early in the life
cycle which means that if there are any mistakes they can be
handled sooner
• It is more suited to larger projects which ABC* technologies handle
• Software is produced early in the software life cycle thus there is
enough time for testing
