Visualization of Guidelines on Computer Networks to Support Processes of Design and Quality Control

Industrial companies supply products intended to satisfy customers’ needs and requirements. To be competitive and to maintain good economic performance, efficient systems are needed to communicate information and exchange knowledge. Such systems are often referred to as quality systems as they intend to support development as well as standardized work regarding the quality of the product and increase satisfaction of the company’s customers and other stakeholders (employees, owners, sub-suppliers, society). Many companies try to structure and improve their quality systems by applying the international quality standard ISO 9000, which can result in extensive documentation. The guidelines and instructions of quality management systems are traditionally documented and presented as paper documents, alternatively on an intranet (a company’s internal computer network) suitable for printouts. These however, do not correspond to some company’s requirements for usability in daily work and as support to interest and engage the personnel in development work. An assumption was that visualizing guidelines using different kinds of multimedia technologies such as hyperlinked and animated pictorial illustrations might be relevant to support quality control and design processes in industrial companies. Two objectives were set up: The first was to explore how the usability of guidelines could be improved by changing the interface design of the guidelines; The second was to explore how the visualization process of guidelines could support participative design by applying evaluations and interpretations in a dialogue form between two individuals or among a group of individuals. The methodology that has been used to generate research questions as well as methods is based on theories of action research and experiential learning. Various methods have been used and combined in order to collect information and to ensure the reliability of the findings based on it. Three industrial companies participated in a first case study. They had conventional quality systems, which they wanted to replace or improve. The companies set up design teams to establish principles for visualizations of their quality systems on their intranets. Cooperating with the author, the design teams created and evaluated computer supported prototypes. These prototypes were made available via the Internet and discussed within each design team. The teams exchanged ideas and comments to enhance their prototypes. The results showed that a quality system should be visualized by an overview of the physical production plant. Information about different processes and instructions are represented by hyperlinked symbols within or next to the plant layout. A second field study aimed to clarify how industrial companies with certified quality systems according to ISO 9001 visualized their guidelines and instructions of construction, production, and installation. The quality manager at each company evaluated the existing system and explained their needs of developing the system by means of computer supported visualization on their intranet. The information was collected through telephone interviews and on site visits. The results showed that the companies would like to improve the visualization of information by decreasing text and increasing pictorial descriptions, such as flowcharts and animations. They also experienced that a quality system on the companies’ intranets was or should be an enhancement in order to disseminate and update the information. A third case study performed in collaboration with Saab Automobile showed results that corresponded with the other studies. The company wanted to replace their conventional information system of ergonomic design guidelines for cars, and design a new system based on interactivity and multimedia. The results showed that a pictorial overview of the car with different areas hyperlinked to further information was preferred. The specific information in the ergonomic guidelines was illustrated with icons, pictures, animations, and some text. In a comparison with the conventional system, subjects performed working tasks faster and with a more positive attitude in the new system. A fourth case study was performed within the GM company group, which showed the need of a formalized working process throughout work with human simulation tools as well as possibilities to document the information generated. A human simulation system prototype was modeled in collaboration with the companies and was presented on an intranet. The results indicated a great potential to enhance the communication within and between the companies, increased accessibility to knowledge, and increased quality on performed work. To summarize, the studies in this thesis show a need among industrial companies to visualize guidelines in information and quality systems by means of multimedia and an interactive design process. Such an approach supports knowledge acquisition and communication, and has a potential to ensure high quality in a company’s processes and products. Furthermore, the users’ attitudes tend to become more positive to the information presented compared to a conventional system

Computer supported visualization to support continuous improvements within quality systems

This paper presents a study wherein computer supported visualization is used to design and enhance understanding of quality systems. The study attempts to discover if a quality system such as ISO 9000 can be visualized, and how the visualization should be designed in order to support continuous improvement. Three companies in southern Sweden have set up special groups (here called design groups) whose purpose is to establish principles for models to visualize their quality systems on the Intranet. Their goal is to find a web-based solution that eliminates problems with updating documents, but that also supports understanding as well as reflection about how to improve existing routines and workflows. The design groups create and evaluate computer supported prototypes and exchange ideas via the Internet. The companies prefer descriptions containing local symbols (pertaining to just their company) that connect non-physical aspects, e.g. communication, with the physical environment. They also prefer the use of pictures as much as possible, since this makes the context more understandable. A quality system based on visualization will have better possibilities to engage personnel in the quality work; it will be faster, easier, and more interesting to use than systems with paper documents or other text based systems on the intranet

Course Supervision Challenges in PhD Education

A large portion of the PhD education in Sweden is dedicated to courses. This made it interesting to explore potential course supervision challenges in the PhD programme. A multiple-case study was conducted to identify such challenges and explore how these are perceived by students and supervisors at the Faculty of Engineering of Lund University. By interviewing students and supervisors in five different research groups, insights were gained into how the main stakeholders reason about courses. The findings indicate that courses that are to be included in the education are characterized by a large degree of freedom tailored to individual student needs and preferences. However, the type, timing, availability, value, and convalidation of courses are challenges that limit this freedom

Engagerande föreläsningar enligt principer för erfarenhetsbaserat lärande med stöd av filmer, övningar och bildspel

Drivkraften i denna studien har varit att utveckla en föreläsningsmetodik som skapar engagemang och utrymme för reflektion vilket är en förutsättning för lärande. Föreläsningstillfällena bygger på principerna för ett erfarenhetsbaserat lärande med visuellt stöd i form av filmvisning, bildspel, interaktiva övningar och bildbaserade åhörarkopior. Resultaten visar att föreläsningsmetodiken upplevdes som mycket eller ganska bra. Studenterna var positiva till de varierade undervisningsmomenten under föreläsningen och diskussioner i samband med dessa. Totalt sett ansåg studenterna att det var en engagerande föreläsningsform där tempot eventuellt kunde ha varit högre
