Structured Systems Analysis and Design Method (SSADM) Timeline

The Structured Systems Analysis and Design Method (SSADM) is a highly structured, “waterfall” methodology developed in the 1980s for the UK government to standardise IT project management. Its timeline can be viewed through two lenses: its historical evolution as a standard and its internal execution phases

Historical Evolution Timeline

SSADM evolved through several versions to become an “open” standard used widely in public and private sectors. 

  • 1980: The Central Computer and Telecommunications Agency (CCTA) evaluates various analysis and design methods.
  • 1981: Consultants from Learmonth & Burchett Management Systems (LBMS) are selected to develop SSADM v1.
  • 1983: SSADM is made mandatory for all new information system developments within the UK government.
  • 1984–1986: Version 2 (1984) and Version 3 (1986) are released, with the latter being adopted by the National Computing Centre (NCC).
  • 1990: Version 4 is launched, introducing more refined modules and stages.
  • 1995: SSADM V4+ is announced, followed by the release of V4.2.
  • 2000: The CCTA rebrands SSADM as “Business System Development,” repackaging it into 15 core modules with additional specialized modules. 

Methodological Execution Timeline (Stages 0–6)

SSADM follows a strict linear sequence where each stage must be completed and “signed off” before the next begins. 

  1. Stage 0: Feasibility Study – Analyzes technical, financial, and organizational feasibility to determine if the project is cost-effective.
  2. Stage 1: Investigation of Current Environment – Models the existing system using Data Flow Diagrams (DFDs) to understand current data and processes.
  3. Stage 2: Business System Options – Presents up to six different ways to build the new system, allowing users to choose the best strategic direction.
  4. Stage 3: Requirements Specification – A complex stage that builds a full logical specification of what the system must do, including Entity Life Histories (ELHs).
  5. Stage 4: Technical System Options – Evaluates hardware and software architectures to determine the best technical implementation.
  6. Stage 5: Logical Design – Defines user dialogues, update processes, and enquiry processes in an implementation-independent manner.
  7. Stage 6: Physical Design – The final stage where logical specifications are converted into real hardware and software database structures and program specifications.

Jackson Structured Programming (JSP) Timeline  by year

Jackson Structured Programming (JSP) was developed by British software consultant Michael A. Jackson to provide a rigorous, data-driven alternative to the intuitive “top-down” methods prevalent in the 1970s. Its evolution is characterized by a transition from micro-level program design to macro-level system architecture. 

The Early 1970s: Foundation and Invention

  • 1970: Michael Jackson founded his firm, Michael Jackson Systems Limited, to fully develop a new program design methodology.
  • 1974: The name Jackson Structured Programming (JSP) was coined by the company’s Swedish licensee.
  • 1975: Jackson published the seminal book Principles of Program Design, which formally documented the JSP method and is now considered a classic. 

The Late 1970s: Standardisation and Expansion

  • 1977: JSP reached global recognition, being taught in universities and used across Europe, the US, and Asia.
  • Government Adoption: The UK government adopted JSP as its standard program design method under the name SDM (System Development Methodology).
  • Industry Use: Large organisations like the World Health Organization (WHO) began using JSP as a standard for specifying programs. 

The 1980s: Evolution into System Development (JSD)

  • 1980: Jackson published JSP, A Practical Method of Program Design, further refining the technique for practical industry use.
  • 1982–1983: Jackson, along with John Cameron, introduced Jackson System Development (JSD). While JSP focused on individual programs, JSD expanded these principles to entire systems.
  • Integration: JSD was widely incorporated into the UK’s SSADM (Structured Systems Analysis and Design Method), specifically for entity and event modelling. 

The 1990s to Present: Legacy and Modern Relevance

  • 1990s: Jackson introduced his third major method, Problem Analysis (or the Problem Frames Approach), focusing on requirements and software specifications.
  • Legacy: While JSP has faded from mainstream daily practice due to the rise of Object-Oriented Programming, its core concepts—like deriving program structure from data structures—influenced modern practices like Event Storming in Domain-Driven Design (DDD).
