This paper describes two experimental studies that examine the differe
nce between software training manuals for new users of a groupware sof
tware package. The manuals differed in terms of their elaboration of p
rocedural, conceptual and usage information. It was expected that manu
als with rich conceptual and usage elaborations would produce the best
learning outcomes. No significant differences were found in the learn
ing outcomes of subjects with either high or low levels of previous co
mputer experience. The elements that influence the development of inst
ructional manuals are analysed from the perspective of our findings. T
he paper suggests that examining the underlying relationships between
procedural, conceptual and usage information is an important topic for
understanding and evaluating design guidelines for instructional manu
als. Research into the methods used to communicate this information ma
y provide insight on the usage and development of instructional manual
s.
