Bruce Tuckman (1965) proposed the four-stage model called [[Forming-storming-norming-performing|Tuckman's Stages]] for a group. Tuckman's model states that the ideal group decision-making process should occur in four stages:

* ''Forming'' (pretending to get on or get along with others)
* ''Storming'' (letting down the politeness barrier and trying to get down to the issues even if tempers flare up)
* ''Norming'' (getting used to each other and developing trust and productivity)
* ''Performing'' (working in a group to a common goal on a highly efficient and cooperative basis)

Tuckman later added a fifth stage for the dissolution of a group called ''adjourning''. (''Adjourning'' may also be referred to as ''[[mourning]]'', i.e. mourning the adjournment of the group).  This model refers to the overall pattern of the group, but of course individuals within a group work in different ways.  If distrust persists, a group may never even get to the norming stage.
