About SorenProject CV (pdf) CV and interests Publication listProject failures and curesLarge IT projects may be damaged in many ways, for instance large cost or schedule overruns, unsatisfied users, or disappointing business results. I have investigated several large projects and identified 37 damage causes and 22 cures. The electronic land registry Electronic health record - EPICWant help to write problem-oriented requirements? Simply send a message to: slauesen@itu.dk Problem-oriented requirements - SL-07 Danish versionTraditional requirements describe what the system shall do. Problem-oriented requirements (SL-07 requirements) describe what the system is to be used for. They cover all kinds of requirememts, are five times shorter, five times faster to write, and five times faster to reply to. Y-Foundation requirements CMS requirements Use cases vs. SL-07 tasks Textbook and papersIT Contracts (in Danish)Requirements are often appendices to long contracts. IT-people don't read the contract and lawyers don't read the requirements. It need not be so. SL-07 requirements have an 8 page contract with 4 appendices. Together they cover what traditional 50 page contracts with 16 appendices do.UX and systematic design of user interfacesThere is a big gap between UX specialists and software developers. UX specialists are good at identifying user needs and testing whether usability of the user interface is adequate. However, they are rarely able to design intuitive and efficient user interfaces. Nor are programmers. There are no systematic design methods. At best it is trial-and-error. Lauesen invented a design method (Virtual Windows) that gives a minimum of user screens, good data overview, efficiency for professional users, and fast development. The health record screen at the right was developed with this method. Mini-course in the method Some great user interfaces Microsoft Access tutorial UX papersData visualization and UvisProfessionals need overview of complex data, so good data visualization is crucial. Uvis is a tool that allows IT-interested users to develop interactive, complex data visualizations. The health record screen at the right was made this way. Visualization papersEHR - Electronic health recordsLauesen has been involved in many aspects of EHR. Here are some links: The early national EHR strategy Graphical and customizable EHR Anonymizing an EHR Troubles when deploying EPIC Time study of EPIC in the clinicIT architecture and software engineering (in Danish)Lauesen has worked in software engineering since 1962. He wrote his first tutorial in 1969, developed operating systems, studied why SW research wasn't used in industry, how perfectionism killed usefulness, and fought hype about OO, SOA and IT-achitecture. |
