chapter 1) the ''root''of all this knowledge is an activity called 'Manage dependency'.The three basic types of dependencies (described in chapter 1) give rise to the first three specializations of the 'Manage dependency'activity: 'Manage flow', 'Manage sharing', and 'Manage fit'. In addition the three subparts of managing flow dependencies give rise to three more specializations of 'Manage dependency'. They are called 'Manage prerequisite', 'Manage accessibility', and 'Manage usability'.Each of these six types of coordination, in turn, has a number of ''bundles''which contain further specializations of these generic coordination processes. For instance, 'Manage sharing'includes bundles like 'How is sharing managed?''What kind of resource is being shared?'and 'When is sharing managed?'Within these bundles are various kinds of sharing mechanisms such as 'Manage by manager decision', 'Manage by market', and 'Manage by chance {lottery}'.In some cases these generic coordination mechanisms even include further specializations that describe specific examples. For example, 'Manage by market'includes a specialization called 'Manage recruiter time by market bidding'that was added as part of our project about new ways to do hiring (described in chapters 1 and 12).Much more information about coordination theory is included in section II and detailed descriptions of some of the specific kinds of coordination knowledge included in the handbook are provided in chapter 3.
