Data science survival and growth within the corporate jungle: An easyJet case study

14:0514:45 Wednesday, 23 May 2018

Who is this presentation for?

Data scientists, data science leads, analysts, airline fans

Prerequisite knowledge

A general understanding of the field of data science

What you'll learn

- Get a detailed view of how data science looks like within a large corporation with a lot of different data sets and internal customers. - Understand the most common problems data scientists face and learn about some innovative ideas to tackle them, based on real-world experiences. - Understand how data science can solve problems in the airline industry.

Description

What does it take for a data science team to move from statistics and model design to actually delivering value within a corporate environment, where customers have very different backgrounds and requirements?

With 500,000 flights and over 80 million passengers a year, internal teams specialising in operations, maintenance, scheduling, network expansion, pricing, consumer preferences, marketing and inflight retail, and a growing data science team, easyJet is a representative example of a diverse environment with a lots of opportunities and even more potential traps for aspiring disruptors.

Some of these challenges include:
- Business problems require a variety of approaches/techniques to solve, often extending beyond core data science skills (e.g. operations research, web development). Expert support from IT and other functions is often unavailable.
- Data scientist turnover can lead to projects being discontinued.
- Business teams have their own legacy systems that they swear by and scepticism or resistance to change is common.
- Business functions are often not fully aware of what they want to achieve when engaging the data science team.
- Data sources are distributed/isolated or even completely inaccessible.
- Bringing models into production can mean different things and there is a trade-off between what is useable and what is fast to create.

In this session we will go through a number of projects from easyJet’s recent past and give practical advice on how we solved these challenges and how we have adapted our processes, structure, collaboration practices and infrastructure, in order to avoid many of these in the future. The projects we will touch upon are:
- Predictive maintenance: We worked alongside the engineering team to propose optimal replacement times for the thousands of electrical and mechanical components found in an Airbus aircraft.
- Slot matching: We worked with the scheduling team to create an interactive tool that matches our commercial schedule with airport slots, given user constraints and costs.
- Food waste: We collaborated with the inflight team to minimise food waste, based on machine learning techniques.
- OTP forecast: We built a model to predict when flights arrive on time and inform operations to take pre-emptive action, using customised visualisations.
- Pricing: We have developed a number of ML algorithms to optimise pricing decisions and augment the capabilities of human pricing managers.
