Demand Driven Performance using Smart Metrics net-net.

By Debra Smith and Chad Smith backs up from MRP II to Orlicky’s original MRP algorithm asking managers to disconnect least unit cost in exchange for throughput flow. And go forward using smart metrics for a demand driven operating model. All good stuff. Where I disagree is illustrated by the authors commentary and many neat examples the model is based on complexity theory. By this claim, in another cyclical time, complexity theory dictates different metrics will control the model. We’ve seen this pattern repeats before. Low demand MRP. High demand use Finite scheduling, APS, ProfitKey, RedPepper. Demand changes, The Goal from Dr Eli Goldratt came into vogue.
As an aside I posit the real solution is build an adaptive software solution on a foundational data model designed for complexity theory. Many solid examples have been commercially proven in the adjacent computer science recommendation systems used by the social networkers. Google’s PageRank algorithm, backrub is continually tuned and adapts to a big data massive scale graph. Unfortunately the three top incumbent databases: Oracle, SQL Server and DB2 all ladle on graph as a reporting tool. At best algorithms hardly adapt as the relational database model underneath is frozen. A solution is putting the demand driven model into a Graph Database. C/o DARPA, Lawrence Livermore Labs, NSA, and a cadre of social and startups via universities, Neo4j and GraphLab being two standouts, a fundamental rewrite is a forward now option.
Alas, we have to deal with backwards incumbacy of really quite old ERP and Manufacturing Systems most based on 20-30 year old design and database. And the FT economists sees no end to our current low demand in advanced economies. May as well implement the Demand Driven Operating Model as wrap-around or layer with existing ERP systems using Smart Metrics and enjoy the benefits - Now.

Lock-free Algorithms for Ultimate Performance by Martin Thompson 55mins
The most amazing achievement of the computer software industry is its continuing cancellation of the steady and staggering gains made by computer hardware industry.

Distributed algorithms for message-passing debunk the notion that EnSW can’t do effective consistency, ACID compliance over the WAN, et al. For too long the Consumer Internet has thrived, while information silos have stopped information flowing between enterprises in real-time, negating innovation. I’d hazard this is about the change.

The Gillmor Gang live on the Dreamforce 2013 show floor.Steve Gillmor and the Gang including Rackspace’s technology evangelist Robert Scoble discussing mobile advances and the once again dramatically changing tech landscape. The Gillmor Gang events are always very interesting to watch. Highly recommended!
