Presentation On CORADMO

CORADMO Presentation Transcript: 
CORADMO(Constructive Rapid Application Development Model )
COCOMO II model extension
Focuses on software development schedules and costs using RAD techniques.

COCOMO II is tuned to modern software life cycles.
COCOMO II is really three different models:
The Application Composition Model
Suitable for projects built with modern GUI-builder tools. Based on new Object Points.
The Early Design Model
This model is used to get rough estimates of a project's cost and duration before you've determined it's entire architecture.
The Post-Architecture Model
This is the most detailed COCOMO II model. It is used after development of the project's overall architecture

Rapid application development (R.A.D) is a software development methodology that uses minimal planning in favor of rapid prototyping.
The "planning" of software developed using RAD is interleaved with writing the software itself.
The lack of extensive pre-planning generally allows software to be written much faster, and makes it easier to change requirements.

4.Need for CORADMO
COCOMO II Schedule shortfalls:
Better suited for software cost experts
Does not easily support cost estimation by analogy
More knowledge is required to use
Requires specification of many parameters
Time-consuming to use

5.Constructive Rapid Application Development Model
schedule (months, M)
personnel (P)
adjusted effort (person-months, PM)
Based on
Effort and schedule distribution to the various phases
Selected schedule driver ratings impacts on the M, P, and PM of each phase.

The Constructive Application Development Model utilizes a new COCOMO II extension that allocates effort and schedule to the stages, which are anchored at points in a development life cycle, namely :
Life Cycle Objectives(LCO),
Life Cycle Architecture(LCA),
Initial Operational Capability(IOC).

7.Physical Model

8.Six Classes of Strategies for RAD
Reuse, Very High-level Languages (RVHL)
Development Process Reengineering (DPRS)
Collaboration Support (CLAB)
Architecture Risk Resolution (RESL)
Prepositioning Assets (PPOS)
RAD Capability of Personnel (RCAP)

9.RAD Opportunity Tree
