Konferensbidrag (refereegranskat)abstract
- This paper analyses the character of usability criteria found in lists, which are used for interface design and evaluation. In order to understand usability criteria and relations between different criteria, a categorization of six usability criteria lists has been performed. The analysis has shown that the formulations of criteria reside on different abstraction levels. The results consist of two knowledge contribution. The first contribution is a hierarchical categorization model. The role of this multilevel abstraction hierarchy is to support practical problem solving processes by enabling and supporting the explicit articulation of criteria for a given context. The second contribution is a categorization of usability criteria. The aim of this categorization is to support the understanding of how different usability criteria relate (e.g. overlap or complement) to each other and highlight possible gaps.

From Usability to Actability
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The paper discusses how theories from the Human-Computer Interaction (HCI) and the information system development fields can be combined in order to achieve more actable, and thus more usable, information systems. More specifically, one aim of this research is to create a reconciliation of the HCI perspectives of usability with the language action perspective into what we call actuability. The paper discusses advantages and limitations found in both the language action perspective and in prevalent HCI theories.

Handlingsbara IT-system - design och utvärdering
- 2005
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Handlingsbarhet är ett perspektiv på IT-system lyfter fram vad som görs vid ITanvändning. Perspektivet innebär att handlingar som utförs av människor och ITsystem kommer i fokus. Handlingsbarhet definieras som: -Ett IT-systems förmåga att utföra handlingar, och att befrämja, möjliggöra och underlätta handlingar som utförs av IT-systemets användare både genom IT-systemet och baserat på information från IT-systemet i en verksamhetskontext.- I detta perspektiv ses IT-system som instrument för teknikmedierad verksamhetskommunikation. Rapporten förklarar utförligt perspektivet och begreppet handlingsbarhet. Bl.a förklaras skillnader mellan handlingsbarhet och användbarhet samt skillnader mellan handlingsbarhet och avbildningstänkande. Teoretiska grunder i form av socioinstrumentell pragmatism redogörs för. Olika modeller och principer för handlingsbarhet presenteras; bl.a en kommunikativ modell av användargränssnitt och den sk ElemantarInterAktionsLoopen. Tio principer för handlingsbarhet presenteras: tydlig handlingsrepertoar, tillgodosedda kommunikationsbehov, lättnavigerbart, handlingstransparent, tydlig feedback, tydligt och lättåtkomligt verksamhetsminne, personifierat, känd och begriplig verksamhetsvokabulär, intentionellt tydligt samt handlingsstödjande. Handlingsbarhet har operationaliserats i form av metoder för design av IT-system samt utvärdering av IT-system. Olika delar av designmetodik beskrivs: Modellering av processer, modellering av systemanvändning, modellering av IT-system. Utvärdering av IT-system beskrivs genom sex strategier som är uppbyggda utifrån ett antal generiska situationer: Målbaserad utvärdering, målfri utvärdering, kriteriebaserad utvärdering, samt IT-system som sådana vs IT-system i användning.

Metodverktyg och användbarhet : en studie av datorstödd metodbaserad systemutveckling
- 1998
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes usability goals for method tools. Method tools are a type of CASE-tool aiming to support computer- and method-based information systems development. The aim of the thesis is to develop knowledge in order to suggest recommendations for achieving more usable method tools. The thesis takes an action perspective. An important starting-point in identifying usability goals are the existing modelling acts in the system development process specifying requirements for how method tools shall be developed.The thesis is performed as a prototyping approach embracing three steps. Output from a previous step is used as input to the following step. Further the thesis is based on studies of real cases where actors have interacted with method tools. In order to gain data I have used questionnaires, interviews and observations. The thesis embraces 12 usability goals for method tools. These goals are empirically generated and theoretically grounded. The identified usability goals are primary oriented towards the use situation system developer, method tool and task. Several usability goals can be characterised as more general and therefore are valid in areas beyond this use situation.The main contributions of this thesis are recommendations for developing method tools, a goal-means hierarchy presenting a composite description of usability attributes for method tools, characterising knowledge in a taxonomic form and a model which describes how modelling acts are related to usability goals.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this research is to suggest a method for collective competence development among IT-consultants. IT-consultants are involved in many challenging situations. They need to manage different organisational,semantic and technical issues. Managing this complexity requires a variety of competences. Examples of competences needed are business development,project management and information system development. The competence developed is often individually based. Due to the competition between consultancy firms it is not sufficient with an individually based consult competence; rather the IT-consultants have to carry joint work procedures of the organisation. A consultancy firm possessing a high organisational competence is selling more than working hours; they are selling a reflected development approach. The competence of the IT-consultants is decisive concerning the outcome in the clients’ organisations. The reasons for suggesting a reflective and structured approach for collective competence development are: 1) many IT-consultants are exchange experiences only hastily and at random. This means an ad hoc development of joint competencies. 2) IT-consultants often collaborate with clients rather than withother IT-consultants. If the IT-consultant is the only representative from the IT-organisation the interaction with other consultants is limited. The character of the IT-consultants’ work situation means that there is a risk that the competencies resides only on an individual level and that they will not be properly transferred to the collective and organisational level. We have been inspired by theories such as: experiential learning, organisational learning,knowledge-in-action and storytelling. The method development has been based on empirical data from two IT-consultancy firms. The main message of the paper is to argue for the need of a structured collective competence development process and that it is not sufficient to rely on sporadic and occasional knowledge exchange.
