Projects and Use Cases

AI Use Cases

I have been responsible for the delivery of AI and Data Science implementations for 80+ businesses. Many are covered by customer confidentiality, or NDAs, but high level details are shared here.

Sales and Marketing Use Cases

• Predictive Customer Analytics - Calculating a range of predictive customer attributes, to support marketing teams with their customer strategies. These attributes include, churn likelihood, in-market windows, life-time value, engagement, product preference, and channel preference.
• Customer Segmentation - Supporting the segmentation of a customer base in a data driven way. Including behavioral-based segmentations, traditional non-supervised machine learning segmentation, as well as supervised segmentation combining customer value with demographic attributes. Used for both retention and social aquisition.
• Recommendation Systems - Online and offline recommendations systems to support everything from displaying recommendations in emails, on webapges, and as part of applications. Covering industries as diverse as fashion retail, building supplies, quick-service restaurants, and music. Recommendations differentiated by optimising predictions to achieve specific business outcomes.
• Marketing Spend Optimisation - Supporting marketing spend through channel analytics, price sensitivity analysis, as well as reinforcement learning based exploration/exploitation approaches
• Lead Scoring - Identifying leads and accounts with highest probability of conversion, and whom should be focussed on accordingly. Key to the success of Lead Scoring is enabling a sales team to prioritise recommended leads as easily as possible

Inventory Use Cases

• Inventory Optimisation - Helping businesses who hold stock know how much to hold, and how much to order. Across a range of industries, business models, and personas; for a mix of core, seasonal, and promotional products; accomodating stock building, fast-fashion style wide-then-deep buying, and supplier constraints like Minimum Order Quantities.
• Forecasting - Improving forecasts, and helping businesses get more out of the ones they already have. Includes validation of forecast performance, and consideration of important concepts like hierarchical forecasting, seasonality, the cold-start problem, and cannibalisation.
• Allocation - Distribute inventory across locations (such as FCs and Stores) in an optimal way. Specific examples include allocation of end-of-season stock across their European factory outlets for leading fashion brands, or distribute fresh produce across a grocery network in order to minimise pemalties.
• Supplier Optimisation - Determining the optimal mix suppliers to aquire inventory from, given arbitrary business rules and constraints; given many-to-one, one-to-many, and many-to-many inventory-supplier relationships.
• Distribution Resource Planning - Managing the distribution of inventory and resources across various locations to optimize efficiency and meet demand, assuming a network of stock and a distribution capacity that can be utilised.

Pricing Use Cases

• Price Sensitivity Modelling - Analysis of price sensitivity and its drivers, to act as decision support for pricing teams.
• Promotions - Developing and optimizing promotional strategies to drive sales and customer engagement, including for close-out. Effective promotion planning usually considers maximising a set of business KPIs like margin, engagement, and sell-through, given constraints (such as the promotion window)
• Quote Price Optimisation - Optimizing pricing for quotes and proposals to improve win rates and profitability. By dynamically adjusting quote prices based on customer value and market conditions, businesses can increase sales effectiveness.
• List Price Optimisation - Using AI to optimise standard list prices, to balance revenue and market competitiveness. Often requires exploration of the pricing surface through bandit style solutions.

Generative AI Use Cases

• Explainability - Bridging the gap between quantitative forms of model explainability, and natural language (of the domain being considered).
• Natural Language Interfaces - Automation of business-supplied constraints to a model in a non-technical way, granting business users more autonomy when using a solution, and in turn helping them move faster

Strategy Support

• AI Project Delivery - Ground up development and design of AI-centric project delivery framework. Flexible enough to accomodate deliveries ranging from mostly-standard to fully-bespoke, and accounting for the unique challenges faced in AI delivery around factors like Scope, Feasibility, Value, and Adoption.
• Strategic Insight - started and grew an insight analytics consulting team, with a focus on actionable and commercially impactful insight. Turned this into a commercial offering that was so successful Peak changed its broader sales strategy around it.
• Adoption and Change Management - Often, delivery of a powerful AI application is the easy part and getting end users to trust it and adopt it's outputs is much harder! It is critical to start these conversations early and to ensure end user workflows are appropriately understood when developing a solution. Taking experience of 80+ successful AI deliveries, started small AI Adoption CoE with responsibility for supporting on our most challenging (usually enterprise) adoption cases.
• General AI Strategy - over the years, I have consulted a number of businesses on how to develop and execute an AI strategy. Three of the most common challenges businesses have are:
  • Identifying the write use cases for AI in your business
  • How to recruit, retain, grow, and structure a mixed team of AI professionals
  • Maximising commercial (or product) impact of data analysts, data scientists, and ML Engineers

Industry Partner Collaborations

• AWS - Supported launch of AWS ML Marketplace, by delivering the first 6 business-focussed models
• AWS - Support launch of AWS Forecast and Personalise products
• Intel - Support Intel with testing of new chip for acceleration of industry AI solutions

Open Source Software

• citrus - R package for customer segmentation. Available on CRAN
