Compression Between Build & Fix Model, Waterfall Model and Incremental Model

S. No

Build & Fix Model

WATERFALL MODEL

INCREMENTAL MODEL

1

No need for Documentation.

Need of Detailed Documentation in waterfall model is Necessary.

Need of Detailed Documentation in incremental model is Necessary but not too much.

2

Requires less project but early stage planning is needed

In waterfall model early stage planning is necessary.

In incremental model early stage planning is also necessary.

3

High amount of risk as there is no real mean to access the risk.

There is high amount risk in waterfall model.

There is low amount risk in incremental model.

4

There is short waiting time for running software in Build & Fixed model.

There is long waiting time for running software in waterfall model.

There is short waiting time for running software in incremental model.

5

No time limit is defined by user/developer(s) for development.

Finite time duration for development.

Finite time duration for development.

6

It can be used for small projects

Can be used for large project.

Can be used for large project.

7

Flexibility to change in incremental model is Easy.

Flexibility to change in waterfall model is Difficult.

Flexibility to change in incremental model is Easy.

8

Cost of Build & Fix Model is high due to a large number of iterations.

Cost of Waterfall model is Low.

Cost of incremental model is also Low.

9

Testing is done in Build & Fixed model after every iteration of phase.

Testing is done in waterfall model after completion of all coding phase.

Testing is done in incremental model after every iteration of phase.

10

Returning to previous stage/phase in incremental model is possible.

Returning to previous stage/phase in waterfall model is not possible.

Returning to previous stage/phase in incremental model is possible.

11

In Build & Fixed model, large team is not required.

In waterfall model, large team is required.

In incremental model, large team is not required.

12

Requires less experience to execute or manage other than the ability to program.

Need good experience to execute and manage including the ability to program.

Need good experience to execute and manage including the ability to program.

13

There is multiple development cycles take place in Build & Fixed model.

There is only one cycle in waterfall model.

There is multiple development cycles take place in incremental model.

14

Whole project is developed and tested. However changes can be made again and again.

Whole project is developed and tested and changes can be made after successful completion.

Smaller modules are developed and tested and integrated after successful execution of all the individual modules.

15

Good user satisfaction. As user/client is involved in development each process or development stage.

Poor user satisfaction as user/client can check / see his application after first successful development of the project.

Good user satisfaction as user can check / see hi application after the development of each individual module.
