Order from Chaos - Developing Use Cases

Using the metaphor of a jigsaw puzzle from the previous blog, we inferred the necessity of technology to tame the complexity of a system that is in a state of constant change but which nevertheless must be managed and guided such that it meets key objectives at the individual and enterprise level. The major problem is that jigsaws never come with instructions on how to build order out of chaos – and the individual approach is usually random, based on trial and error!

 

With any project, be it building a house or fixing a washing machine, a manual is essential. To have any chance of arriving at a destination when setting out into unknown territory, it is wise to have a plan or a map. Without these instructions one can lose track or get completely lost. In the enterprise, when teams lose the focus of project objectives, this translates as financial loss or project failure.

 

Similarly, a Use Case is a documented record that describes a procedure for interaction with a system and when these records are collectively available they stimulate discussion, which generates ideas for improvements and efficiencies. A Use Case approach forces the consideration of users and customers, which can help elicit feedback and create a dialog to help build better systems. The interaction or cooperation generated creates added value. These records provide transparency, agreement and shared awareness, acting as way markers in a broad landscape of procedures that are foreign to many, as individual knowledge is often siloed.

 

Although Use Cases are valuable and provide a positive return on investment in time and resources, their development is also takes time. For many different teams however, they lay a foundation for future reference. Enterprise Architect is an indispensable, time saving tool in the Use Case development process.

 

In mid 2013 Sparx Systems conducted a webinar showcasing model driven development of Use Cases. This informative session reviewed the rich features of Enterprise Architect that can assist in the key processes of analysis, development and testing, saving time while replacing random processes with best practice and creating consensus and clarity between stakeholders.

Enterprise Jigsaw Puzzle

 

Imagine that a group of people are putting together a jigsaw puzzle whose pieces continually change shape as do the spaces that they must eventually fill. Each group has responsibilities to the completion of the overall puzzle but more importantly must develop their own respective piece of this puzzle and ensure that ultimately, that piece seamlessly complements those shared boundaries created by the relationships of others. This scenario of mutual dependencies and volatility could be analogous of any organisation in the current hyper-competitive business environment.

 

 

 

Of course each team can communicate with others throughout the project, but without a fully shared vision, collaboration will be sub-optimal. Ideas and innovations will remain siloed within each group and should the puzzle ever be completed on time and to budget, it will have many disconnects, repetitions, gaps, and missing pieces. Some groups will produce excellence, but no group can fully share its value with the others.

 

 

 

Ultimately, someone must have overall responsibility for coordination of the effort and more importantly management of inherent risk, resources and timelines, all of which demands access to technology solutions. Each piece, complementary space and multi-shared relationship in the puzzle requires collaboration between many different stakeholders.

 

The plan and co-ordinated approach shared by each team responsible for each piece must be captured at the beginning and the ability to communicate and share progress at the individual, team and organisational level must be made transparent, simplified, and accessible to everyone.

 

 

 

The responsibility for Enterprise Architecture falls to the Chief Enterprise Architect. However, the creation of the architecture is a shared task. Stakeholder equity of access to enabling technology is imperative - and it must be affordable. Every role, including managers, analysts, systems architects, and engineers must have sufficient understanding of the strategy detail, allowing them to make informed decisions and to execute the plan that leads to realization of the shared vision.

 

 

 

Enterprise Architect provides the ultimate collaboration solution, transparently interlinking all of the individuals and groups in a shared vision, while enabling an inclusive and contextual decision history across the local and global locality of the project teams. Enterprise Architect is an enterprise requirements definition and management platform, with full support for collaboration including authoring, validating, and managing requirements, and communicating those requirements to the broader team through seamless integration.At any future time, and as the delivered solution evolves to meet changing business objectives, the thread of those original decisions can be continually reviewed, tracked and monitored to ensure complete traceability.

Enterprise Architect Community

Catch Software is a proud partner of Sparx Systems and is pleased to sell and support their industry-leading UML CASE tool, Enterprise Architect. We love engaging with the Sparx Community, and as part of this, we host User Groups in New Zealand and Australia every two months.

If you’ve not attended a User Group before you may not be sure what to expect.  User Groups are gatherings held for Enterprise Architect users and enthusiasts. A presentation is given by one or more speakers, followed by group discussions on common interests, challenges and best practice. Here is an overview of the User Group we hosted in Auckland this September.

Why Auckland Council chose Enterprise Architect

Janet Wilkinson from Auckland Council presented to a diverse range of Enterprise Architect users. Auckland Council has been using Enterprise Architect for about a year and Janet talked to the group about the thought process behind them choosing Sparx Systems' Enterprise Architect and outlined the challenges the Council faced.  She went on to cover their requirements, which included architectural modelling to facilitate strategic decision making, project solution modelling and design at all levels for projects. Summing up, Janet shared examples of the types of results they are starting to see.

The attendees at the User Group were very interested in this presentation, with several questions asked and everyone engaging in conversation.

There was a real sense of collaboration at the event and it was fantastic to see the Sparx community working through common issues together and offering solutions.

In this article I will show you how to estimate a software project using Sparx Enterprise
Architect (EA)which is a famous CASEtool. (I used EA 7.5 in this article)
Based on Rational Unified Process (RUP), In order to estimate software projects duration, you
need to recognize the project features and requirements first. This leads you to Use Cases that are
cores of a software project analysis model and you cannot estimate any software project without
recognizing its Use Cases. Requirements, Features and Use Cases recognition are usually done in
the first phase of RUP, Inception.

As an Enterprise Architect user, you may have had the need to apply several times more or less the same set of elements on a given diagram, leading to numerous uses of copy and paste as new.

The "copy and paste" feature on a selection of elements, including their associations and layout works ok, but there could be a more suitable way to go about this. Given a context where we have our set of elements i.e. a pattern of modelling elements available from one or several diagrams within our model, we need to apply them several times onto a new diagram. Once the new diagram is created, the elements that need to be duplicated aren't available from this blank diagram. Hence the diagram that contains those elements has got to be opened first, followed by a selection on the elements of interest, copied to the clipboard (Ctrl+C). Then the newly created diagram needs to be displayed again so the paste as new command can be executed (Ctrl+Maj/Shift+V). We also need to ensure that any specific element or information, e.g. an activity description or a child composite diagram and its sub-elements, mustn't be re-used, hence they need to be deleted.

Enterprise Architect makes it possible to re-use a set of elements, their associations, any notes, and their layout on the diagram by creating UML patterns. Similarly to the use of design patterns (GoF), the aim is to define a set of elements that can be applied for modelling purposes.

In the following example, a test case has been represented by modelling each step to follow as a node within a UML activity diagram, e.g. : pre-conditions / initial context, expected result, test result (OK/KO).

We can abstract these elements to be represented as re-usable steps, shown here :

Once our pattern is defined in a standard diagram, such as the UML activity diagram above, we can save it into an Enterprise Architect UML pattern : open the Diagram menu > Advanced > Save UML Pattern, and save into a new XML file (e.g. C:\basic tests patterns.xml). Enable the "Merge" option if you need in some cases to merge a given activity (or another node) from your pattern with an existing activity from the target diagram (active diagram).

To import and have this pattern available from an EA project, open the Resources view (use the Project menu > Resources if this view is not displayed on your EA client), and right click onto UML patterns, choose "Import UML pattern", and browse to the UML pattern's XML file.

Your UML pattern is now available to use on your Enterprise Architect project ; it should be displayed within the list of UML Patterns. Simply drag and drop this pattern onto the current diagram to create a new test step with expected and test results, as defined in this UML pattern. This window lets you rename each element before it is created.

Of course UML patterns can be applied from any type of diagram (UML class, UML state machine, BPMN, SysML BDD, etc.) or model (analysis, design, tests, architecture, etc.).
