duration). The “process” names the business process and thus the project phase in
which the LL was gained. Therefore, project team members can specify their current
environment as well as the current situation to search the EB for similar experiences.
Observations are facts that are of interest to future projects, often expressing some
baseline (e.g., “it took 10% of the total effort to manage the project”) or some positive
effect (e.g., “the customer was happy because we provided him with a ready-to-use
tutorial”). Problems are descriptions of negative situations that occurred during a
project (e.g., “the expectations of the customer were not met”). Guidelines,
improvement suggestions, and pragmatic solutions relate to one or more problems.
Guidelines are recommendations on how a particular business process should be per-
formed. For example, a guideline could be the following: “Interact with the customer
frequently, at least twice a month.” An improvement suggestion is a proposal to
change an artifact to avoid problems that occurred during its usage. Pragmatic
solutions are sequences of immediate countermeasures taken by a project team in
response to a recognized problem. While a guideline aims at preventing a problem
from occurring in the first place, a pragmatic solution is applied after a problem has
already occurred.

Fig. 7 . CoIN's technical infrastructure (INTERESTS)
The technical infrastructure, called INTERESTS (INTElligent REtrieval and
STorage System), is shown in Figure 7. It consists of a tool layer for accessing and
presenting the EB contents using a standard web browser, a general purpose EB
server, and a commercial CBR tool (orenge from empolis, Germany), which is used
for the actual EB.
