Introduction
In April, we published a report on Digital Textbook Sales in U.S. Higher Education, in which we outlined sales for e-textbooks over the next five years based on current trends and variables. This series — The Transformation of Textbook Publishing in the Digital Age — provides an in-depth look at textbook publishing in Higher Education, and offers a roadmap for evolution and profitability in the industry. In the first installment we discussed New Business Models. Specifically, we listed these four shifts that current textbook publishers should consider to remain competitive in their market niche.
In the second part of the series we looked at four new product models
In this post, I want to step back for a moment and outline briefly how textbook publishers can measure product value and measure potential profitability in a digital world.
A Formula for Profitability
As I have pointed out in the previous posts in this series, the digital future of learning materials translates to greater competition for textbook publishers. It will also require them to adopt agile business practices that bring products to market more quickly and generate more revenue streams from existing content.
As we look at the next decade, the following general product categories represent the primary product niches for textbook publishers. Let me provide a brief description of each, and then move on to my formula for measuring viable and profitable products.
Within each of these product categories we will see many individual product types. This means that publishers will need to spend ample amounts of time with experimentation and the valuation of content and products. Products will evolve more quickly and companies will no longer have the luxury of multi-year product planning and development. As a result, publishers will need to be in a constant mode of experimentation with product types and their potential value. The problem is that all of our models to date are based upon a single product vision — the print textbook. As we move into a mostly digital world, we will need to work on new models for product valuation and forecasting.
With that in mind, let me offer up some preliminary thoughts on how to evaluate learning products in the digital age (the next decade). First, here are the general criteria that all products must meet to even make it off the drawing board.
With these factors in mind, we can establish a basic formula for product profitability as the ratio of product cost to product value, multiplied by the product’s flexibility value. In this formula, flexibility is represented by a value of 1-10 based on a quantitative scale measuring product flexibility (not shown here).
(cost : revenue) * flexibility = product value
Here are two graphics that show how this formula for product profitability, as well as the assumption behind it, can be applied in order to measure product viability.
The first graphic shows a grid that breaks down the value components of the major product categories for textbook publishers over the next decade. Each value component in the grid is assigned a value of High, Medium, or Low that correspond to unique numeric values for each category.

In this quadrant diagram, you can see the various products charted in terms of their value based on the formula for profitability.
