Big data is messy because it involves combining different types of information from various sources that do not always align perfectly. Messiness also arises when data is extracted and processed since it is being transformed into something else. Additionally, behind every data point is a person, and incorporating people introduces complexity when analyzing big data. Unlocking insights from big data requires accounting for human behaviors and perspectives that complicate analyses.

2. Using All Available
Data
• It is feasible in an increasing number of contexts. But it comes at
a cost.
• Data is fluid, huge, powerful, unpredictable, uncontrollable and
not a scare resource.
• The abundance of data is the result of the instrumentalisation of
the natural, industrial and social worlds.
• A key point about the reality of big data: behind every data point
is a person, and when people get mixed up with technology and
analytics, things get messy.
• So unlocking big data through smart systems have to account for
the very human, very messy Big Ideas that sometimes complicate
things.

3. Add More Data
Points
• Increasing messiness by combining different types of
information from different sources, which don’t always align
perfectly.
• Messiness can arise when we extract or process the data, since
in doing so we are transforming it, turning it into something
else.
• Messiness itself is messy.
