Agile Software Architecture Sketches and NoUML

Understanding the software architecture of what you're building can prevent chaos and encourage collective code ownership. In the race for agility though, many teams struggle to do this, particularly since they've abandoned UML in favour of "boxes and lines" sketches. Moving fast requires good communication, but how do you do this without resorting to big design up front and UML?

A Proposal to Enhance the UML Notation

Raul Rugiero proposes an enhancement to the UML notation whereby requirements and test cases, in particular acceptance tests, are strictly related. Agile methodologies highlight this aspect basing themselves on test driven approaches. The notation of UML use cases may be enhanced in order to allow enhanced UML tools to properly handle links between use cases and tests.

Wireframes: A Great Way to Start Development Projects

In this article, Andreas Wulf introduces wireframing as a simple and effective way to kickstart your development projects. Wireframes allow you to present your ideas in a tangible form so that can be shared and debated (without writing any code). By leaving out graphic design details, wireframes are not only quick and easy to create and change, they help us stay focused on the “big picture”.

How to Integrate Models And Code

While creating models in a form or another is very common, their combination with the code has been challenging. As a result, models are usually thrown away once the implementation has progressed. The reason is partly in the modeling languages used and partly in the tools applied. The article describes proven practices for working with both models and code.

Modeling Failure Scenarios in Systems

The increase in number of integrated systems in today’s enterprise solutions necessitates dealing with dependency and environment failures in a systematic way. By modeling dependency failures at the architecture stage, system response to failures can be communicated, tested and implemented reducing the business risk and cost.

Agile Modeling: Enhancing Communication and Understanding

Modeling supports us in communicating and understanding when we create software solutions. As communication and understanding are two of the most critical aspects of delivering software solutions - modeling is a valuable tool that should not be overlooked. Agile Modeling adheres to and aligns with Agile values and principles and should be one of the practices within your Agile toolkit.

Staying Safe and Sound Thanks to MDSD

In this article, Andreas Kaltenbach explains how Model-Driven Software Development (MSDS) can help solving backward compatibility problems when creating a newer version of a software which can mean a new API or a new database schema that old clients cannot use. MSDS is used to negotiate the differences between versions to ease the upgrading process.
