the lattice of value - designing products for self-growth
download PDF version on this bulletin
(110K) In 1998 some colleagues and I were working on the business plan for aQtive,
subsequently funded by 3i. As we considered at our product range and marketing budget, we realised
that traditional marketing was too expensive and we looked for ways in
which our products could 'market themselves'. One of the results of this was the 'lattice of value' a way of looking
at products to both assess how well suited they are to self-growth and
how they can be modified to improve their ability to grow. This theme was followed up later within aQtive in the modelling and analysis
of market ecology
modelling of the interactions between market groups and the potential
for designing products to maximise growth through those interconnections. The key to getting a product used (and bought!) is value. Do the users
perceive that they will gain more value form it than it costs them
whether in effort or money? To achieve self-growth we want users/customers to influence one another
because someone else uses product A I want to use product A or
some associated product too. This is a form of co-value I gain
additional value from my use of product B because you use associated product
B. Although I didn't know it at the time there is a whole literature on
the economics of this network externalities and network effects
[e.g. Brynjolfsson, 1996; Economides, 1996; Liebowitz , 1998; Weitzel,
2000]. Economists are interested in the phenomena as it means that free
markets may not work to optimise production in the way that traditional
theory suggests. From a design viewpoint however, we can take advantage
of the effect to increase market growth. One of the most obvious examples of this phenomenon is telephone use.
The first user of the first telephone has no value from it (apart from
it being a hi-tech ornament) as there is no one to call. The millionth
telephone customer has far greater value as there are 999,999 existing
telephone owners to talk to! Furthermore the first telephone user now
has a more valuable product because others have bought telephones too. Figure 1. critical mass This leads to two effects: The lattice of value captures the conditions for products to achieve
self growth when there are two types of users and products. It was developed thinking particularly of web-site developers and web
users, but is not confined to these groups. Suppose we have two products A and B. Product A is designed for web site
owners and product B is a companion product for web site users.
for example, Adobe Acrobat Exchange to produce PDF documents and Adobe
Acrobat Reader to view them. Figure 2. the lattice of value We want these products to have the following value properties (figure
2): (i) (b) is better than (a) it is better for a web developer
to use product A than not, even when there are no users of product B (ii) (c) is better than (a) it is better for a web user
to use product B than not, even when there are no web sites using product
B (iii) (d) is better than (b) if a web site uses product
A then there is additional value for the end users if they have product
B as well (iv) (d) is better than (c) if users have product B it
is even better if the web site uses product A as well Both (i) and (ii) are boot-strap properties, they get the product started.
This avoids the critical mass problem there is value even when
there are no other users. Strictly only one is essential, but getting
both is even better! The other two properties (iii) and (iv) are the co-value properties ensuring
growth. The first of these (iii) means that web developers who use product A
want users to also use product B, so become promoters of the product (producer
push). For example, if you use Macromedia Shockwave on your site you encourage
your web users to download Shockwave player. The second (iv) means that users of product B actively want web sites
to use product B, either explicitly through comments or suggestions to
the web master or implicitly because the web developers knows their users
want it consumer pull. Let's imagine we are thinking of producing a tool to help web developers
create site maps. The tool will run on the developer's machine, crawl
the web site and produce a site map that can be included in the site to
help users navigate round it. Figure 3. web developer site map tool On its own this product only satisfies condition (i), assuming it is
good, it is better for web site developers to have it, but there is no
companion product to promote growth. Possibly if we have a 'powered by'
logo on the site map other web developers may see it and adopt it, but
we have no associated web-user product. So, we look at some sort of client-side downloadable product that acts
as a browser plug-in, and builds site maps of pages the user has visited.
A kind of history that also keeps track of site structure. Figure 4. web user site map application This second product satisfies (ii), again assuming it is well designed,
and so users may adopt it, but it has no relation to our developer product. To get this interaction we add some features to the products. First of
all we update the developer's tool so that it automatically uploads a
site summary file whenever a site map is produced. This file includes
information about changes to the site and possibly information about each
page such as title, keywords, etc. We then make the end-user product look
for this additional information and if it is there incorporate the information,
giving the end-user an instant site map with information about changed
pages, the ability to search the site by keyword etc. Figure 5. updated products Let's look again at the co-value proposition ... First of all (iii) if you are a user of a site with the site map,
you already have the site map, but it doesn't know what you have visited.
By downloading the end-user application the value of the site map is augmented. Similarly for (iv) if a user has the end-user application then
sites with the extra summary information are easier to use and have extra
information about changed files etc. . Conditions (i) and (ii) are also important for growth. Suppose the product has property (iii), but not (ii) and a user encounters
a site that uses product A. Although that site may become better if the
user gets product B, other sites are not improved. So unless the gain
is really big, or the site really important it won;t be worth the effort. Similarly, if (iv) holds, but not (i) we would be asking the web developer
to adopt a new product just to help an individual user. Note that (i) and (ii) may actually be negative. For example, designing
a web site to work well with a particular browser plug-in (for example,
basing the site on Shockwave) which means increased value for those users,
but makes the site less good for other users. Also note that we need to be a little careful in looking at value for
(iii) and (iv) as there are two kinds of value value for the developer
and value for the user. For the web these are often aligned value
for the producer means a better web experience and so value for the user.
However, this is not always the case, for example, if we made the end-user
site-map plug-in upload site usage data, which would add value for the
developer, but not the user. Designing an appropriate lattice of value
for a product means that we need to make sure that conditions (iii) and
(iv) are true for both developer and user. Products can achieve self growth without all the conditions holding,
in particular (i) and (ii), but usually only if there is some alternative
way of achieving critical mass. One way is shear market force. For example, if Microsoft delivers a product
free with the standard Windows installation generating a consumer pull
(arguably the situation with IE's special features). Acrobat similarly
benefited from Adobe's market presence and large PR effort. Another way is to reduce costs on either producer or consumer side. For
example, there is no value to having Acrobat reader if you never encounter
a PDF file condition (ii) fails. However, Acrobat reader is free
so that even modest gains to the user of obtaining the reader when encountering
an Acrobat document (condition (iii)) outweigh the costs of obtaining
the reader (download). Early on in Acrobat's adoption even this was not strong enough as slow
modem speeds made downloads expensive in terms of time and for some telephone
costs. However and alternative market group, documentation producers,
had a different value balance as they could deliver Acrobat to end-users
on the same CD ROM as the documentation itself. This lead to penetration
of the reader into end-user groups and thus consumer pull to use PDF documents
on web sites. This shows that growth is not just about one or two market
groups and products, but about whole webs of interconnections. This is
the study of market ecology.
