PACT analysis

• used to scope a problem in a particular domain (sphere of activity)

activities incontexts

technologies

Requirements

Opportunities

People

PACT analysis

• People have differing characteristics

• physical differences (eg. weight and height, senses, disabilities)

• psychological (spatial ability, language, attention and memory) = support mental models

• usage differences (novice, advanced, homogenous vs. heterogeneous

PACT analysis• Activities need to be considered by the design

team

• purpose of the activity = important

• frequency (eg. everyday or once a year)

• cooperation (alone or with others)

• complexity (simple, complicated)

• safety critical (dangerous, errors)

• nature of content (amount of data)

PACT analysis

• Contexts are where activities occur

• physical context (eg. environment)

• social context (eg. privacy )

• organizational context (eg. within companies, organizations)

PACT analysis• Technologies are used to perform functions

• input - people enter data, commands (eg. wiki postings)

• output - receive data (eg. video on YouTube)

• communication - between people and devices (cellphone)

• content - form and accuracy of data (eg. YSDN website)

Scoping a problem with PACT

• Important to harmonize the PACT elements in a particular domain

• Useful to understanding current situation and look for opportunities

• This can be done by scoping out the variety of Ps As Cs and Ts

• observing and talking to people - user study to generate requirements

Requirements

• goal is to bring about something new in what people do or might want to do

• are generated by conducting user research

• interviews

• observations

• by analyzing this data, designers get a better sense of what the system will need to do

Start a PACT Analysis• think about the communities in our public

spaces

• how are the communities defined ?

• contexts

• activities

• technologies

• What are some communities we have identified in our public space research?
