Forecasting in Real Life

12PwC – Athens Big Data Meetup
Forecasting in
Business:
The right
questions to
ask each
organisation
12PwC – Athens Big Data Meetup
❑ How predictable is your demand?
❑ Are you using the optimal algorithms?
❑ Could you forecast at a micro level?
❑ What new data could you use to improve accuracy?
❑ What is the best accuracy you can hope to achieve?

13PwC – Athens Big Data Meetup
So, how can an organisation optimise their accuracy to drive true business outcomes…
By continually
testing and
refining how
they forecast…
Segment demand into predictable micro clusters at SKU and location level
Test and assign the optimal algorithms to each micro cluster
Define where human intervention is required and where the machine works best
Continually test impact of exogenous factors
Learn from each planning iteration and measure how close you got to optimal accuracy

14PwC – Athens Big Data Meetup
…and ultimately harness data-led insight in the whole spectrum of decision-making?
Forecasting may enable not only
strategic decision-making by
facilitating decisions that may impact
an organisation’s demand planning
strategy and the realisation of its
marketing objectives…
…but also operational decision-
making by managing decisions on
day-to-day operations, often in real-time,
aiming to achieve a new, sustainable
and significantly higher operational
efficiency level
