This article presents a preliminary dialogical analysis of how mundane
social activities are planned and how the resulting plans are acted u
pon. We trace some of the history of the distinction between situated
and cognitive accounts of actions. We argue that the polarized dichoto
my between planned and situated actions is unhelpful, and we try to un
dermine that dichotomy by treating preparation for action (in which pl
ans are produced) and acting with plans as everyday dialogical activit
ies. The restricted definition within cognitive science of plans as me
ntal representations completely specifying sequences of behaviors fail
s to do justice to mundane plans. We propose that plans can be treated
as performatives that regulate and coordinate multiparticipant social
activities. Plans are, however, more than just words; they may involv
e recruitment and construction of tools in preparation for activities.
We analyze preparation for activity and acting with plans with help f
rom cooking recipes, do it-yourself handbooks and instruction manuals.
With an apology to the Czech nation, we also make use of Jaroslav Has
ek's (1974) book The Good Soldier Svejk.
