# HP SPaM

HP SPaM (Hewlett-Packard Strategic Planning and Modeling) is an internal consulting group that supports HP businesses on mission-critical strategic and operation decisions. As evidenced by its publications and awards, SPaM has been a prominent example of the deployment and practice of OR/MS (operations research and the management science) in large companies. Together with HP Labs, SPaM represents HP at the INFORMS Roundtable, a group of organizations whose purpose is to promote OR/MS excellence in practice.

## History
### Contributions

SPaM pioneered and leads innovation in supply chain and procurement practices. They created dramatic improvements in manufacturing, distribution, procurement, product design, forecasting, metrics, and inventory control efficiencies; leading to the publication and adoption of their methods outside HP. Notable contributions include:
   * Popularizing and helping to drive the adoption of postponement in high-tech products, as a gain in efficiency in building responsive supply chains that support a high variety of product versions (SKUs or stock keeping units) and configurations
   * Developing and popularizing the concept of using a single metric to measure the full end-to-end costs associated with carrying inventory, to support better supply chain decisions.
   * The use of simple, practical spreadsheet tools to deploy the power of advanced statistical inventory target setting to a broad range of businesses.
   * Popularizing the concept of product design for supply chain; leading product development teams to minimize end-to-end costs for design, production, distribution, and support instead of focusing solely on minimizing material costs and development schedules as was previously common practice.

### Founders

The team was established in 1989 by Corey Billington (currently a professor at IMD) who had recently joined HP and was working with Sara Beckman (currently a Senior lecturer at UC Berkeley). Billington asked then HP CEO Lew Platt for $100K to start a team focusing on efficiency and inventory within HP. Soon after, Corey added Tom Davis, Paul Gibson, Steve Rockhold, Rob Hall, Marguerita Sasser, and Ed Feitzinger to the team and began a collaboration with Hau Lee (then a young Professor at Stanford and currently the Thoma Professor of Operations, Information, and Technology at Stanford Graduate School of Business) and M. Eric Johnson (then an HP employee 1988-1991 and now Professor and Director of the Glassmeyer/McNamee Center for Digital Strategies at the Tuck School of Business at Dartmouth).
The name SPaM came from HP internal location code (LOCXXXX STRAT PLAN MODEL) initially assigned to the group during the days of limited identification fields. SPM and SM were two initial possibilities but the group settled with the more pronounceable SPaM. This was the day before internet era where spam was not yet synonymous with unsolicited or undesired bulk electronic message.

### Logo

The triangles in SPaM logo represent inventory – the largest asset on the balance sheets of most consumer electronics manufacturers and certainly the largest asset of HP. The blue bell shape represents uncertainty (including bell-shaped normal distribution) which exists in most decision making situations. The combination of the shapes is meant to represent SPaM's intention of using analytics to enable decision making under uncertainty to improve asset management performance.
