Project failures and damages
- Large IT projects may be damaged in many ways, for instance large cost or schedule overruns, unsatisfied users, or disappointing business results. Sometimes the damages are so severe that the project is closed (complete failure). I have investigated several projects and identified detailed causes of damage, e.g. that project owners trusted tech hype or accepted a solution description without understanding it. I also provide suggestions on how to prevent the causes. Service-oriented architecture (SOA) is often a cause of damage. So I have included a detailed investigation of two ways to integrate systems: The ideal SOA and the shared database. Further there are detailed reports on two of the systems: The Electronic Land Registry and the health record system (EPIC). See more
Data visualization and electronic health records
- UVis - a tool for development of interactive graphical user screens
Visualization of health records (pdf, 2015)
Visualization with formulas (pdf, 2013)
UVis allows IT-interested users to develop complex data visualization screens. "Programming" the screens is done by formulas much like spreadsheet formulas. Real programming is not needed. We have developed the tool and used it to develop an electronic health record system with advanced data visualization.
You can download a free trial version for MS Windows. Unpack the zip file to a folder called for instance uVisTrial. It contains the tool and the health record application. Open the Readme file to see how to run it. You don't have to install anything: uVisTrial.zip 26-10-2017 (The previous version of the tool couldn't open in Windows 10. It opened briefly, then minimized. Now repaired).
- Anonymizing a large health record database
Short paper (pdf, 5 pages, 2011)
Long paper (pdf, 13 pages, 2016)
As part of the uVis project, we anonymized a large relational database of electronic health records. This was much harder than anticipated. Structured data in the tables were relatively easy, but identifying data could also hide in free-text notes. We also had to ensure consistency so that data still gave a correct picture of the patient's medical history.
Problem-oriented requirements - SL-07
Traditional IEEE 830 requirements describe what the system shall do. Problem-oriented requirements (SL-07 requirements) describe what the users want to achieve and which problems to remedy. The requirements leave it to the supplier to describe how his solution supports the users and handles the problems. The customer can assess how well this solution supports the users and use this in the supplier selection.

The template is a problem-oriented requirements specification for a complex system, an electronic health record system. It can be used as inspiration and template for other systems. It covers functional requirements, security, usability, integration, etc. The guide booklet explains what to write and not to write, contract issues, test issues, etc. The booklet is available on-line above. You can also buy the English as well as the Danish booklet on www.amazon.com, www.amazon.de and www.amazon.co.uk.

- Requirements for the Y-Foundation
Twice a year, the Y-foundation assesses around 300 applications and give grants to some of them. The process is quite complex and involves applicant, secretay, assessment board, auditor, payments and a new web-site. They needed a system to support them. From January 2013 to March 2013, Lauesen made the analysis and wrote the requirements based on SL-07. He managed the acquisition until completion in Sept 2014. The requirements, the supplier's proposal, and other project documents are available (anonymized): See more
- Use case experiment - hotline system (updated 11-01-2012)
In 2009 we conducted an experiment where several professionals and researchers specified requirements for a hotline support system. We got eight replies based on traditional use cases and seven based on SL-07's task descriptions. It turned out that use cases couldn't cover the customer's needs in areas where improvement was important but difficult. Tasks didn't have these problems and were better in other ways too. See more
