Okay, I think one misconception about B2B product marketing is that we assume that all products have to be custom-designed, not true. The reality is that you have this wide distribution in terms of characteristics of B2B products. In fact, in some cases, some B2B products are more like B2C products. So in many respects marketing of those kind of products which here are referred to as standardized products, can be like B2C marketing. Then you have services which are a totally different animal altogether. So we will have a separate course on service marketing. So I will defer to Professor Samichet to tell you about the key guidelines in terms of service marketing. And then you have this lovely type of product and I do call them lovely in the sense that they're almost like a hybrid. To some they're like standardized products, especially in the sense that they can be mass produced. But in terms of the end product, they look really customized. So they enjoy the advantages of both in terms of cost but also in terms of the perceived value. And this gets us into this very important concept developed by Narayandas at Harvard Business School called the Value Stack Concept. And it's the notion that a product can be modular. Any product can be modular if we think broadly enough. Especially in terms of all the different components that go into a product. Also separating the tangible part with the intangible part. And so it behooves you to know how to stack all these different components of the product. And this is important because we're dealing with many types of decision makers in the so called buying center, and depending on the situation you're in, we can strategically reconfigure or even de-feature our value stack. So, if we look at this chart we see that in this assumed buying center you have five members involved. Manufacturing, R&D, purchasing, IT and logistics. And on the top of each buy center member, we also have the component of our product that each member is most interested in. So in the case of manufacturing it could be user convenience. For the R&D member it could be technical advancement. For purchasing it could be first cost. For IT it could be system compatibility. And for logistics it can be a total cost. So again, each member is interested in something different, even though they're all a part of our total product. So in this next slide, we see our original configuration and in the original configuration which is labeled A, number five is most emphasized. Though we can even think of this as being a sequence. So total cost especially if we're targeting logistics at first from AB even top management at first that will be have A playing the value of this product. But unfortunately we don't always deal with logistics. We don't always deal with the top management in many cases we deal with the procurement office first. They're much more interested in the up front price, and it may be framed in a very negative way. If our up front price factoring in how our total cost is lower, It's very high. So we may be disqualified, we may be left out of the supplier or vendor list right off the bat. So this is where we strategically emphasize that part of the product which will grab the attention of the purchasing department. And lastly when we see the last configuration, C, there we have eliminated four, one, and two. So this the no flows model that can appeal to maybe more small to medium sized companies. So again, there's a lot of wiggle room in terms of how we can configure, and reconfigure, and maybe even decrease how we stack our product. So, summing up, we learned in the segment that B2B Product is value-based. We learned how important to think about a pre-marketing, main marketing, and post-marketing, which I called TPS, and it involves a team efforts because captains may vary by different stages. And we learned how vary B2B products maybe and so some B2B products were more like B2C. And lastly we learned about this very important concept called the value stacked, where we can target different buying center members with a differentconfiguration of our product.
