- In large organizations there are usually rather large groups of heterogeneous users with different tasks and different needs. Their requirements would most likely vary a lot when the system is designed to grant them access to different parts of the functions and applications In our earlier work we have tested the interface concept of Multi-Layered Design (MLD) on an operating system where each layer had a set of applications and tools. The users working with the system could get access to different applications depending on their level of experience or their different needs. The current paper presents how the MLD concept is taken one step further; implementing a layered design in a multi-user portal on a Citrix server. When a network solution is used, new available possibilities are given. The MLD approach can be combined with a role based access technique can the layered structure can be used in different ways for many different groups of users. In the study a MLD mushroom structure is employed where the user category decides the set of layers the different user groups can choose from while the individual user’s tasks and experience guide the choice of the specific layer. Thin clients are used to access the layer structure and five personas are made to represent the potential user groups. The results show that MLD can be used within a Citrix environment and that it is a viable alternative or complement for multi-user portals

- Software engineering has proposed the use of formal and industrial methods, models and tools within software industry for some time now. There are several good examples like the aircraft industry, branches of the military, the space shuttle development and the nuclear power plant industry that have come a long way with their software processes. However, there is still an ongoing dilemma of how to better introduce software processes within most regular production industry. In this paper we try to summaries our experiences of software processes and quality systems within the vehicle industry of northern Europe. A first investigating case study is conducted at a large software consulting company, focused on industrial software, and then we further investigate the software situation at one of the largest vehicle manufacturers in Scandinavia. We use a ten point list with adapted metrics to evaluate process quality and create a progress report of the work-flow and process implementation rate. Based on our results from the evaluation we also provide a first set of guidelines for how to level the differences in quality processes for hardware and software development.

Konferensbidrag (populärvet., debatt m.m.)abstract
- When creating software, people from many different areas are involved. To make them work efficiently together they need to communicate but communication requires a common language and common understanding. The Unified Modeling Language (UML) is often used as a common ground for understanding when modeling and designing software products. However, after practically working with many large projects we have found UML to have shortcomings in the area of modeling Graphical User Interface (GUI). There are many other ways to model GUIs but it could be beneficial to use a modeling method that the more technical developers are familiar with and also beneficial to be able to put in the interface into the framework of UML when it comes to drawing applications and code generation. In this study we first of all have investigated the possibility of adding GUI design to UML and then we have explored different solutions for what a GUI UML-diagram could look like and what problems there are with diagrams when it comes to visualizing objects. We have then put forward an idea for a GUI diagram or an UML extension; a graphical element diagram, and discussed its benefits and drawbacks. © 2009 IADIS.

Konferensbidrag (refereegranskat)abstract
- In the process of developing computer based applications the use of descriptive models to depict the architecture and design of the application is practical and brings many advantages. The most commonly used standard today is the Unified Modeling Language. There are many tools that implemented support for this standard for modeling, and they vary in functionality. A comparative study, including a selection of these tools, will show advantages and disadvantages for each tool. The purpose of this study is to test a selection of these modeling tools for a typical three-tier layered web service application. The tools tested in this study are Microsoft Visual Studio 2005 .NET Beta, PowerDesigner and Visual Paradigm. Rational Rose would have been included if it would have supported C#. In this study tests are performed in regard to modeling a class diagram, forward engineering to source code from the class diagram and reverse engineering from source code to class diagram. Despite the shortage of diagram types MS Visual Studio proved to be the most reliable tool for this particular type of applications.
