SSADM Diagram Software - Structured Systems Analysis and Design Methodology
Perfect SSADM Diagramming software with rich examples and template. Edraw is ideal for software designers and software developers who need to draw Jacobson's Use Case Diagram
Introduction - Structured Systems Analysis and Design
SSADM (Structured Systems Analysis And Design Method) is
another method dealing with information systems design. It was developed in the
UK by CCT (Central Computer and Telecommunications Agency) in the early 1980s.
It is the UK government's standard method for carrying out the system analysis
and design stages of an information technology project.
SSADM has been
traditionally used for the development of medium or large systems. However, one
variant of SSADM is "Micro SSADM" which is for small systems. SSADM starts from
defining the information system strategy and then develops a feasibility study
module. These are followed by requirements analysis, requirements specification,
logical system specification and a final physical system design.
Edraw contains special shapes and settings for creating
SSADM Diagrams. Use case diagrams illustrate how the outside world interacts
with elements of the application system.

SSADM consists of 5 main stages (which are broken-down in several sub-stages).
The 5 main stages are:
Feasibility Study: The Feasibility Study involves a high level analysis
of a business area to determine whether it's feasible development for a particular
system. Data Flow Modeling and (high-level) Logical Data Modeling can be used as
technique during this stage.
Requirements Analysis: In the Requirements Analysis stage, requirements
are identified and the current business environment is modeled, business system
options are produced and presented. One of these options will be chosen then
refined. Data Flow Modeling and Logical Data Modeling can be used as technique
during this stage.
Requirements Specification: In the Requirements Specification, the
functional and non-functional requirements are specified as a result of the
previous stage. Data Flow Modeling, Logical Data Modeling and Entity Event
Modeling can be used as technique during this stage.
Logical System Specification: In the Logical System Specification, the
development and implementation environment are specified, and the logical design
of update and enquiry processing and system dialogues are carried out.
Physical Design: During the Physical Design stage, the logical system
specification and technical specification are used to create a physical design
and a set of program specifications.
Who Can Use Them and How
- Software developers: Represent
software applications using the Unified Modeling Language (UML) notation.
- Software developers: Illustrate and
interpret software application relationships, actions, and connections.
- Program managers: Show high-level
static software structures in presentations and specification documentation.
Unlike rapid application development which conducts
steps in parallel, SSADM builds each step on the work that was prescribed in the
previous step with no deviation from the model. Because of the rigid structure
of the methodology, SSADM is praised for its control over projects and its
ability to develop better quality systems.
