The Paper
1. A case study illustrating how personas were used in a real world situation to engage project members with user information during a 2-day workshop to redesign APOSDLE (3rd Prototype)
2. The strengths and weaknesses of personas based on our experience
3. The strengths and weaknesses of actively involving stakeholders in creating and using personas

The APOSDLE project www.aposdle.tugraz.at
• Advanced Process- Oriented Self- Directed Learning Environment
• A 48 months R&D integrated project involving 12 organisations from five countries (contract no. IST-027023)
• Aims to support work-integrated learning by providing people working in knowledge-intensive industries the infrastructure needed to acquire, understand and communicate knowledge

Why Did We Turn to Personas?
1. A work-based formative evaluation of the 2nd prototype highlighted various usability problems such as:
• Ambiguous terminology (e.g. Learning Events, Knowledge Artefacts, Learning Goals, Context)
• Unclear interaction and processes - (Where to begin? What to do? Where is ‘search’?)
• Individual differences (e.g. The Learning Events did not always fit the users’ needs and objectives)

Why Did We Turn to Personas?
2. International Multi-Disciplinary Consortium
3. Varying views, perceptions and understanding of APOSDLE’s target audience – Lack of common language to describe end users
Centre for HCI Design
Why Did We Turn to Personas?
4. Information about end users was provided in the early requirements stage by stakeholders representing future clients and empirical studies, but was not visible throughout the project
5. Referring to users as Knowledge Workers, Knowledge Seekers and Knowledgeable Peopledid not provide essential rich information about the target audience and its work environment

Main Criticism of Personas (Chapman and Milham, 2006)
• Methodological weaknesses - Personas are difficult or impossible to verify – Are they realistic representation?
• Practical limitations - It is not always clear how the personas are reconciled with other data and who is responsible for interpreting them
Centre for HCI Design
Creating the APOSDLE Personas• Empirical data (interviews, observations)
• Stakeholders representing APOSDLE’s target clients contributing an initial set of personas describing their employees based on a template
• Reason 1 - Validation – Getting the right personas
• Reason 2 - Time constraints
Centre for HCI Design
The Four APOSDLE Personas
Rigid work process Flexible work process
Senior employee
Junior employee
Pierre - mechanical engineer Eva – consultant
Paul – Intern (Engineering) Lisa – Project assistant

Redesigning APOSDLE with Personas • 2 Day workshop
• 4 Personas
• 21 participants (None have ever used personas)
Stage 1 – Familiarisation session – Get to know the personas
Stage 2 – Review prototype 2 from the personas’ point of view and consider redesign
solutions if necessary
Paul (the intern) is probably
question driven and requires
detailed knowledge. He carries
out a single task at a time Pierre (the senior engineer) is
probably more set in his ways .
He deals with processes,
simulations and calculations
Persona Familiarisation SessionGeneral comments about each persona
Centre for HCI Design
Persona Familiarisation Session• How do the personas perceive APOSDLE Prototype 2?
• “What aspects of APOSDLE is Pierre more likely to appreciate?”
• “What aspects of APOSDLE is Pierre less likely to appreciate?”
Centre for HCI Design
Persona Familiarisation Session• Participants extrapolate new Information about the personas and APOSDLE
Eva will not use
APOSDLE’s process
view. Her work is less
about ‘ticking boxes’
Eva would appreciate
being able to locate
experts using
APOSDLE
Redesigning APOSDLETo better suit the needs of the personas
“Interesting idea. Who do you imagine using this feature?
Eva? Paul? Lisa? Pierre?”
“Is this a feature a 48 year old senior engineer
in your company might use?”
Addressing Practical Limitations of Personas
Stakeholders help interpret and use the personas
Centre for HCI Design
Rapid Persona-Driven Prototyping During
the Workshop
Viewing the domain
elements could help
Paul get an overview
and explore the
domain
Eva and Pierre
require quick and
unstructured access
to resources
“Will Paul like this kind of thing?
I wonder if people will go through this process.
I can imagine Paul simply pressing ‘ask’ and
bypassing the form.”

Design Outcomes• Learning Events in Prototype 2 could alienate Pierre and Eva
Participant 5 (Programmer): The
Learning Events were created to
facilitate learning. I think we should
reflect on the four personas and see if
they have need for this information. We
are discussing low-level details and
terminology before addressing the
users’ real goals.

Design Outcome

Strengths and Weaknesses of Personas
based on our experience
•Short life span – Had a strong impact
during the first few hours of the discussions
and then their impact diminished
•This could be attributed to the
stakeholders’ presence
•Having to constantly ask participants to
link their ideas to a persona became
tedious and potentially annoying
•Focused the discussions on real people
and real working environments
•Helped project members from different
professional background to ‘get to know’
APOSDLE’s target audience
•Ensured redesign ideas targeted end
users and did not merely reflect personal
preferences
Weaknesses Strengths
Centre for HCI Design
Stakeholders’ Involvement
•Despite a template and instructions,
the style of the initial personas
provided varied
•After a while, participants seemed
to abandon the personas in favour of
asking the stakeholders directly if an
idea could work or not
•Helped produce more valid
personas that captured the work
routine and goals of real people
•Helped interpret the personas and
resolve disagreements - The
personas had clear owners who
knew the people they represented
NegativesPositives

Conclusions
• There are obvious pros and cons to the persona approach
• In our case we conclude the strengths outweighed the weaknesses
• We found personas to be an effective way to encapsulate and communicate user information so it served as a reminder during discussions
Centre for HCI Design
Conclusions
• By combining initial persona descriptions generated by stakeholders with our empirical data we feel we were able to address to some degree methodological weaknesses and practical limitation of the tool expressed in the literature
