Is more information more knowledge?
Does more knowledge lead to take better

Based on data, knowledge, experience,
skills, intuition…
Tacit & explicit knowledge (Nonaka,

DECISION MAKING
13. @MPalomaDBig data for situational awareness and decision making, 2018
SA is being aware of what is happening around you
and understanding what that information means to you
now and in the future
(Endsley et al, 2016)
SITUATION AWARENESS
14. @MPalomaDBig data for situational awareness and decision making, 2018
SITUATION AWARENESS
“is the perception of the elements in the environment
within a volume of time and space, the comprehension
of their meaning, and the projection of their status in the
near future” (Endsley, 1988)
Level 1: perception of the elements of the environment
Level 2: understanding of the current situation
Level 3: projection of future status
15. @MPalomaDBig data for situational awareness and decision making, 2018
SITUATION AWARENESS
Our SA is affected by our goals, preconceptions/biases,
expectations, abilities, experience, training, stress,
workload, complexity of the task…
Our SA influences our decision making process and the
actions we undertake
Systems can be designed to improve SA (individual) and
Activity Awareness (collective SA)

BIG DATA DESIGN
Envisioning useful BIG DATA systems:
DATA

WISDOM
VALUE
FROM DATA-CENTRIC TO USER-CENTRED
GOAL-ORIENTED DESIGN
20. @MPalomaDBig data for situational awareness and decision making, 2018
DESIGN RECOMMENDATIONS (I)
Design to meet the information tasks, goals and needs
• Focus first on the decision making process
• which are the big questions?
• who are the main actors?
• where, when and how are decisions taken?
• Analyse then which data are needed, how to find/sort/filter/
aggregate them
21. @MPalomaDBig data for situational awareness and decision making, 2018
DESIGN RECOMMENDATIONS (II)
To identify tasks, goals and needs, follow a user-centred design
Three main principles:
• Use technology to keep the user in control of the system and aware
of the situation
• Focus on tasks, goals and abilities not (necessarily) on user comments
• Put the stress on human information processing and decision making
22. @MPalomaDBig data for situational awareness and decision making, 2018
ADVANCED INTERACTION
New ways to interact with information (individually and
collectively, co-located and distributed)
Different devices provide different interaction affordances

25. @MPalomaDBig data for situational awareness and decision making, 2018
DESIGN RECOMMENDATIONS (III)
Understand how do people interact with data to generate
knowledge and wisdom
26. @MPalomaDBig data for situational awareness and decision making, 2018
DESIGN RECOMMENDATIONS (IV)
Understand which devices and in which contexts information
processing is carried out
Understand first the problem: design research
Design for user acceptance
Take into account non-rational criteria:
Emotional and semantic design
27. @MPalomaDBig data for situational awareness and decision making, 2018
Design as a research process
A design process involves
• grounding—investigation to gain multiple perspectives
on a problem;
• ideation—generation of many possible different
solutions;
• iteration—cyclical process of refining concept with
increasing fidelity; and reflection
28. @MPalomaDBig data for situational awareness and decision making, 2018
“Design research implies an inquiry focused on producing a
contribution of knowledge… an intention to produce
knowledge and not the work to more immediately inform
the development of a commercial product” (Zimmerman
et al,2007)
“Design science research addresses important unsolved
problems in unique or innovative ways or solved problems
in a more efficient way” (Hevner et al, 2007)
Design as a research process
29. @MPalomaDBig data for situational awareness and decision making, 2018

30. @MPalomaDBig data for situational awareness and decision making, 2018
Design for user acceptance
Acceptance is much more than usability or efficacy
Complex sociotechnological systems
Difference between data science and data engineering

comparison of two theoretical models", Management Science 35: 982–1003
31. @MPalomaDBig data for situational awareness and decision making, 2018
Design approaches
Design to meet the information tasks, goals and needs —>
Design Research approach
Design iteratively taking into account that designing is
providing an efficient solution to a problem given a number
of constraints and resources —> Engineering approach
Design to meet the user capabilities (cognitive and
physiological) as well as the interaction affordances of the
context of use —> HCI approach
32. @MPalomaDBig data for situational awareness and decision making, 2018
Design techniques
Qualitative methods to analyse the problem (interviews,
focus groups, Delphi…)
Lean and iterative design (from wireframes to prototypes)
Participatory design and co-design
Generative design techniques to co-envision solutions
Qualitative methods to assess the results (evaluation trough
UTAUT, NASA-TLX…)

?how to envision a solution for a
future information processing
situation?
37. @MPalomaDBig data for situational awareness and decision making, 2018
Analysing the problem applying a user-centred
approach
who do you ask when the problem doesn’t even
exist yet?
User-centred does not mean accepting the user comments
and suggestions, means focusing on the user needs and
abilities and on the information processing tasks (Endsley et al,
2003)
38. @MPalomaDBig data for situational awareness and decision making, 2018
Analysing the problem applying a user-centred
approach
Interviews and ethnographic studies to understand the
current situation
GTA, wireframes and mockups to envision solutions and test

recovery, alarms, training)

CONCLUSIONS
Big data is much more than data analytics and DATA
The real breakthroughs will come by AUGMENTING human
capability to take decisions using data not by REPLACING
them
This is a wicked problem, exploratory, iterative, generative
and participatory approaches are required
60. @MPalomaDBig data for situational awareness and decision making, 2018
We now live in a world where information is
potentially unlimited. Information is cheap,
but meaning is expensive.
Where is the meaning? Only human beings
can tell you where it is. We’re extracting
meaning from our minds and our own lives
