The economic analysis of basic research in firms has been a growing co
ncern, but only a few attempts have been made to understand the realit
ies which characterize the implementation of this activity. In an in-d
epth case study, this paper considers the organisational specificities
of basic research inside the firm and emphasizes the strategic role o
f human resources. It shows that the process of innovation, which was
seen in the 1970s as a stock of information to be managed, became, dur
ing the 1980s, a sequential learning process which covers a variety of
different but complementary organizational designs in the basic resea
rch unit. On this basis, some analytical implications for technology a
nd innovation processes are suggested. As the production process is a
sequential learning process, an innovative firm strategy is defined as
one which is able to balance short and long terms requirements with r
egard to profitability. This appears as an out-of-equilibrium problem
where the crucial determinant is the organizational design chosen by t
he firm in order to generate and implement new learning and skills.
