| Rational Unified Process |
Rational Unified Process is a system development process for developing systems
with objects and/or components based technologies. It consists of four phases
and nine disciplines. The four phases are executed sequentially while the disciplines
are performed iteratively throughout the four phases.

Phases of Rational Unified Process
|
The four phases are
 Inception
Technical Design - Elaboration
Construction - Coding
Transition
|
|
In addition to the above four mentioned phases, Post project
support is also included in the A7 Technologies? project
development life cycle.
|
|
|
Phase 1- Project Initiation (Inception): This is the explanatory phase
of the project. Project objective and description is described at this stage.
The purpose of this phase is to collect and understand business requirements,
detail the project plan and agree upon a high level statement of work.
This phase identifies the project?s primary objectives, assumptions, constraints,
deliverables and acceptance criteria.
|
|
Phase 2- Technical Design (Elaboration): In this phase, the architecture
of the system is designed. The goal is to translate requirements and specification
into a technical solution to produce Technical Design. High Level Design deals with
overall architecture and framework of the project e.g. project is decomposed into
modules/functions/entities/classes etc. whereas Low Level Design deals with more details
of the project like it incorporates pseudo code and definitions of all technical interfaces
of the project.
|
|
Phase 3- Construction: In this phase, the complete development of
the system based upon the baselined architecture takes place. Here, emphasis
is laid on optimizing costs, schedules and quality
|
|
Phase 4- Transition: This phase includes testing of the product
in preparation of release and fine tuning the product and taking care of
issues like configuring, installing and usability issues. The focus of this
phase is to ensure that software is available for its end users.
|
|
Phase 5- Post Project Support: This is a specific timeframe in which
A7 Technologies would provide support and fixes for bugs encountered in the
functioning of the system. We implement ?Change Request? approach in support phase.
|
|
Disciplines of Rational Unified Process:
|
|
The nine disciplines that are performed iteratively throughout the four phases are:
|
| Business Modeling |
To understand the business of the organization that is
relevant for the system to be developed. Also, if needed,
possibility of re-engineering business process is also explored
and potential strategies are evaluated. |
| Requirements |
The scope of the project is defined. The specification documents are prepared to
identify the functional (like usage, business rules, user interface) and non-functional
requirements of the project. |
| Analysis and Design |
The requirements are analysed and architecture design of the system is made.
This includes designing the network, database, components, modules of the system. |
| Implementation |
The program source code is developed and unit testing is done. |
| Test |
This discipline ensures quality of the system developed. It consists of finding bugs,
ensuring that the system works as per the design of the system and meets all
requirements mentioned in the specification documents. |
| Deployment |
This includes planning and executing delivery of software and supporting
documentations ready to be deployed and making the system available to end users. |
| Configuration and Change Management |
This includes managing baselines of the project, accepting and managing change
requirements, changing and delivering configuration items and managing releases. |
| Project management |
This includes assigning tasks, managing risks, tracking progress etc to ensure on
time and within budget delivery of the product. |
| Environment |
This includes ensuring proper tools are available whenever required. |
