It is tricky to say who defined terms first in the busines press. Value chains have been around for a while. Porter talked about them. So does Moore. Moore also shows why Christensen should have talked more about value chains in his work on disruptive strategy. Let's see if we can reconcile all this into a workable strategy.
Porter's model worked like this (Porter, 60): Inbound Logistics flows into Operations flows into Outbound Logistics flows into Marketing & Sales flows into Service. There are overlays of Firm Infrastructure, Human Resource Management, Technology Development and Procurement. It is handy to remember, as well, that Porter (Porter, 12) compared Competitive Scope with poles of Narrow Target and Broad Target, to Competitive Advantage with its poles of Lower Cost and Differentiation, to yield his Three Generic Strategies of Cost Leadership, Differentiation and Cost Focus/Differentiation Focus. I suggested recently that the Orange County Business Council use the Porter Value Chain model for research they are performing for the Workforce Investment Board because the methodology has been around a while and is seemingly bullet proof for workforce projections. Customers and competitors are crucial to the model, as a firm is always bench-marking performance against the norms.
Moore (Chasm, 12) talked about a bell curve comparing five sequential consumer populations: Innovators, Early Adopters, Early Majority, Late Majority and Laggards. The crucial section (Chasm, 17) described the near certainty that, while Innovators and Early Adopters might like your new product, if you ever want to make money, you'd better figure out a way to "leap the chasm" of failure for most companies and figure out how to sell to the Early Majority, as their buying habits were vastly different from the Early Adopters in crucial ways. In Darwin Moore applies the value chain concept to innovation (Darwin, 38) while enhancing his discussion of the chasm by describing its effects on complex sales and volume sales.
Christensen explores the evolution of the disk drive market (Christensen, 16), pointing to the inevitability that disruptive products (from new, smaller, more innovative companies) are nearly certain to replace sustainably improved products (from main-stream companies). His team at Innosight follows with a methodology (Anthony) to keep your main-stream, not very innovative, company disruptive.
The Boston Consulting Group compared relative market share with growth rate in its Growth Share Matrix (Boston). Question mark divisions become stars or dogs according to the their relative growth rate compared to the competition and the growth of the market. Hopefully, stars become long-term cash cows, not dogs. The message from this is that divisions migrate from section to section according to market conditions.
Moore very usefully attempts a mash-up of all this disparate information. He amplfies Porter's value chain with overlays for complex systems requiring consultative sales processes and for volume operations where the sales process focuses on a closed-end transaction (Darwin, 38). Then, he applies four innovation zones (Product Leadership, Customer Intimacy, Operational Excellence, and finally, Category Renewal) to the Chasm bell curve. For instance, he defines four different innovation technologies that apply to growth markets (Darwin, 73) in the Product Leadership zone of his Chasm bell curve and ranging up to mature markets: Disruptive Innovation, Product Innovation, Platform Innovation and Application Innovation. You have a choice in your company. If you are rapidly growing, focusing on just a few strategies in this range makes sense. If yours is a mature company or - horrors - a declining company, returning to the growth market strategies also makes sense.
Specific strategies are strengthed when you consider the stage of your technology - and your firm.
