The honeymoon era of data science is ending: accountability is coming. Not content to wait for results that may or may not arrive, successful data science leaders deliver measurable impact on an increasing share of an enterprise’s KPIs. Nick Elprin outlines a holistic approach to people, process, and technology to build a sustainable competitive advantage.
How to select the right data science project
Many organizations start with the data and look for something “interesting” rather than building a deep understanding of the existing business process and then pinpointing the decision point that can be augmented or automated.
How to organize data science within the enterprise
There are trade-offs between centralized and federated models (or a hybrid approach with something like a center of excellence).
Why rapid prototyping and design sprints aren’t just for software developers
Leading organizations put prototyping ahead of the data collection process to ensure that stakeholder feedback is captured, increasing the probability of adoption. Some organizations even create synthetic data and naive baseline models to show how the model would impact existing business processes.
Why order of magnitude ROI math should be on every hiring checklist
The ability to estimate the potential business impact of a change in a statistical measure is one the best predictors of success for a data science team.
The difference between “pure research” and “applied templates”
Eighty percent of data scientists think they’re doing the former, but realistically, the vast majority are applying well-known templates to novel business cases. Knowing which is which and how to manage them differently improves morale and output.
Define a stakeholder-centric project management process
The most common failure mode is data science delivers results that are either too late or don’t fit into how the business works today so results gather dust. Share insights early and often.
Building for the scale that really matters
Many organizations optimize for scale of data, but ultimately are overwhelmed by scale of the growing data science team and its business stakeholders. Team throughput grinds to a crawl as information loss compounds from the number of interactions in a single project, much less a portfolio of hundreds or thousands of projects.
Why time to iterate is the most important metric
Many organizations consider model deployment to be a moonshot, when it really should be laps around a racetrack. Minimal obstacles (without sacrificing rigorous review and checks) to test real results is another great predictor of data science success. Facebook and Google deploy new models in minutes, whereas large financial services companies can take 18 months.
Why delivered is not done
Many organizations have such a hard time deploying a model into production that the data scientists breathe a sigh of relief and move on to the next project. Yet this neglects the critical process of monitoring to ensure the model performs as expected and is used appropriately.
Measure everything, including yourself
Ironically, data scientists live in the world of measurement but rarely turn that lens on themselves. Tracking patterns in aggregate workflows helps create modular templates and guide investment in internal tooling and people to alleviate bottlenecks.
Risk and change management aren’t just for consultants
Data science projects don’t usually fail because of the math but rather because of the humans who use the math. Establish training, provide predetermined feedback channels, and measure usage and engagement to ensure success.
