In many cases, the end of the year gives you time to step back and take stock of the last 12 months. This is when many of us take a hard look at what worked and what did not, complete performance reviews, and formulate plans for the coming year. For me, it is all of those things plus a time when I u...
Software Product Line Engineering Resource Kit
Reusable assets made for use with SPARX EA on software product line projects

I recently decided to update the Product Line Engineering Assets I reuse from project to project. In the past I reused a baseline project that contained a folder structure and the UML stereotypes needed to do Use Cases, Feature, and Static Modeling.

For those of you who are not familiar with PLE, below is a context diagram I use to explain it and some links. I also put some of the better books on the topic at the end of this post.

I wanted to enhance that package a little by creating a UML Profile of the stereotypes needed to do Use Cases, Feature, and Static Modeling. Creating a profile makes them available from the toolbox and the resources tree.

I also wanted to recreate an instance of a Product Line Engineering software development process using Software & Systems Process Engineering Metamodel (SPEM) available in SPARX. You can use it as a baseline and tweak it for your project.

I may eventually populate it with the accompanying content. It was originally done in Rationale's XDE, so it mapped to RUP content. I would have to re-map it to OpenUP and other content to make it public.

The resource kit contains:

PLE_Template_Overview.doc- This document outlines the UML profile used to execute Product Line Engineering.

PLEBase.EAP- This project contains two main projects and the PLE UML Profile. One project is a Default PLE Process Instance and the other is PLE Base Folder Structure.

Process PDFs Folder- This folder contain a pdf of each of the phases included in the Default PLE Process Instance. It includes:
-SPE Context.pdf

Imports Folder- This folder includes exports of the resources included in the PLEBase.EAP project. These can be used to import the different assets into your other projects. It includes:
-Default PLE Process Instance.xml

Creating a UML Profile Folder- This is a copy of the material originally posted to the SPARX EA community site.
-Creating a UML Profile in SPARX EA.docx

You can get the Product Line Engineering Resource Kit here.

The following images show the PLE UML Profile in the Resources and Toolbox that is created:

The following images show example diagrams that can be created using the PLE UML Profile.  They are all explained in the downloadable documentation:
