Traceability

How do we guarantee that a delivered system does what it says on the tin?

If you talk to a lot of people about the issue of traceability, most of them will simply brush it off as something that might happen. But without it how do we perform impact analysis in a forward or reverse motion during the system development lifecycle? Traceability is about ensuring that the requirements are realised, looking at a solution and seeing which requirements have been met and knowing that if the requirements are changed, what’s the impact!

Join us and watch how we demonstrate traceability in UML, SOA and TOGAF™

UML

Introduction

A review of the IT landscape, how we arrived at UML and where we believe we are going.

Software engineering principles

Abstraction, encapsulation, modularisation, coupling, cohesion, interfaces and services etc. Are all basic concepts that most people involved with IT use in their everyday vocabulary. This section de-mystifies these terms and sets up a standard language for the rest of the course.

Basic Architectural thinking

Partitioning systems horizontally and verticially, different types of architectural thinking such as TOGAF, RealTime UML and 4+1. Discover why not having a solid architecture can adversely affect the results of a systems development.

Use Cases

Actors, use cases, use case relationships such as includes, extends and generalisations, dependencies, package level thinking, scenarios and a basic introduction to sequence diagrams as a shorthand to modelling use cases.

Activity diagrams

Activity nodes, object nodes and flow, control flow, forking and joining of control flows, decision and merge points, concurrency modelling, signals, using actors on activity diagrams, and interruptible regions. How to ensure your activity diagrams is synchronised with your use case diagrams

Sequence diagrams

Actors/Objects, the importance of the system boundary, messages, focus of control bars, parameters, object Ids, fragments, the correlation between sequence diagrams and activity diagrams, and how to build a sequence diagram from an activity diagram.

Class diagrams

Classes, objects, attributes, operations, associations, aggregation, association classes, dependencies, XOR relations, qualifiers, constraints, multiplicity and cardinality constraints, reflexive associations, homomorphic and metamorphic relations, and inheritance. Building a class diagram from a sequence diagram and by simply reading documentation.

State diagrams

States, transitions, state and transitional behaviour, events, nested states, building state diagrams from sequence diagrams, and actors and objects on a state diagram.

Bringing all the models together

Demonstration of how all the diagrams that have been seen work together to form a single model. Graphic depiction of the relationship between the different models and a demonstration of traceability throught a complete UML model.

Hands on experience

The instructor lead teaching is augmented with a running case study that exercises each concept as it is taught. At the end of the teaching of the above topics, students are given 7 hours to model a complex business problem. This exercise is designed to consolidate everything that has been taught.
