This document discusses big data and surveys. It notes that more data is now created and transferred daily than was stored in 1996. Big data brings challenges like testing hypotheses, requiring significant processing power and time. Surveys allow representative data collection from large populations in a structured way, though questions must be carefully designed to be actionable, differentiating, and linked to business outcomes. Building effective habits may take 2-8 months. The document explores possibilities with big data like predictive modeling and sentiment analysis and emphasizes the importance of employee engagement.

6. WHAT’S GOOD ABOUT SURVEYS?
Relatively cheap to collect &
process data
Allows representative-ness for
large populations
High degree of control in
structuring data collection
Methodological techniques are
well-established, tradeoffs
(e.g. margin of error) are
mostly known

7. GOOD SURVEY QUESTIONS
7Copyright TriskelionGroup 2016. All rights reserved.
ACTIONABILITY:
e.g. Net Promoter Score
• Single question with strong correlations to outcomes
that matter
• What should you do to change it?
SORTING EFFECT:
Differentiates positive and negative outcomes
• Bad question “I believe I am paid fairly at work”
• Good question “I have the opportunity to do what I do
best everyday”

8. BEST PRACTICES IN SURVEY CONSTRUCTION
8Copyright TriskelionGroup 2016. All rights reserved.
Avoid loaded/leading words
Pay attention to question
ordering
Avoid non-specific questions (e.g..
The culture of my organisation is
the right one for the business
environment we are in)
No double-barreled questions
Use unbalanced scales carefully
(e.g. Strongly Disagree,
Moderately Disagree, Disagree,
Agree, Strongly Agree)
Question wording simple: “Do you
have a best friend at work?”
