CBD Research - Summary of results
------------------------------------------------
103 CBD-experts were selected based on their presence on the market or
their contribution to an international conference (WCOP, ICSR, WISR).
Thirty-six CBD-experts - suppliers, researchers and developers - responded
to the questionnaire.
Please find a summary of the final results below.
For more (detailed) information about my research project, including
overall conclusions of my research, please see http://vtraas.cjb.net
Best regards,
Vincent Traas
------------------------------------------------
Please note that the conditions have been ranked according to their rating;
the order therefore does not correspond with the original questionnaire.
The average rating of each condition can be found after the condition,
between brackets
the motivation for each rating is based on a summary of motivations given
by all experts
1. Suppliers have to make it easy for their customers to assess the value
of a component, by offering extensive information (for example demos,
documentation) (8.8)
MOTIVATION: This is a very substantial condition, which sums up perhaps the
most important issue concerning the sales of components. Especially demo's
and extensive documentation are essential for customers.
2. Specifications of components have to be formulated according to a
standard documentation method (7.6)
MOTIVATION: A standard documentation method is considered to be very
important, be it domain specific.
3. The market has to focus on black-box reuse (7.4)
MOTIVATION: Even though black-box reuse is recognized as the 'way of the
future', the market should allow for a significant amount of gray-box
reuse, because CBD is not ready for pure black-box reuse yet.
4. There has to be a generally usable solution for the protection of
intellectual property (6.8)
MOTIVATION: Protecting intellectual property is an issue that deserves
attention, but this should not hamper the flexibility of component
development. Protection: yes, but as long as it doesn't obstruct flexibility.
5. Suppliers have to focus on specialization, advertising, brand name and
image (6.0)
MOTIVATION: Specialization based on specific business knowledge will
increase the quality of supply, and can help create the necessary trust
between vendor and customer. Furthermore advertising (marketing) can
increase the adoption of CBD.
6. Components have to be offered against known/published prices (price
lists) (5.9)
MOTIVATION: Published prices might be a helpful assistance for customers,
but it will still be very difficult to compare components based on prices.
The price may be known, but how to determine whether the component is
actually worth this price? This relates to the first condition.
7. There has to be a (supplier) independent Internet search engine for
components (5.6)
MOTIVATION: While availability of components is recognized to be essential,
the currently present search engines are considered to be sufficient. A
dedicated search engine might of course be practical, but is not necessary.
8. Intermediaries have to set up standard criteria for the comparison of
components (5.4)
MOTIVATION: Criteria for the comparison of components are, as well as
documentation of components, important for customers. However standard
criteria will again have to be differentiated according to domain or
granularity.
9. Intermediaries have to add a quality rating to each component they offer
(5.3)
MOTIVATION: Intermediaries are not (yet) trusted enough to make a quality
rating desirable or feasible. The necessity of a quality rating can also be
questioned: bad components will disappear from the market soon enough,
because (credit) payments will be cancelled.
10. Intermediaries have to supply technical support (5.1)
MOTIVATION: Providing technical support is on the one hand considered to be
the very raison d'être of intermediaries, and on the other hand to be
almost impossible for an intermediary to supply. An intermediary should
provide first line assistance, while the producer of each component should
deal with the more specific details.
11. Components have to be offered mainly by intermediaries (4.6)
MOTIVATION: Trust and concentration of supply are the main issues in play
here, in a positive as well as a negative sense.
12. The market has to focus on fine-grained components (4.6)
MOTIVATION: The market should not only focus on fine-grained components,
but also on medium-grained (business) components.
13. The standardization battle needs to be decided soon in favor of one
object model (3.6)
MOTIVATION: A single standard is not only impossible to achieve, but not
desirable. A (battle for a) single standard might even hamper the
development of the market.
