Content sequencing refers to determining the order in which objectives should be addressed in a lesson or course. The task analysis may be helpful in determining what skills or related or need to be learned prior to other skills.

Clustering refers to determining how objectives will be presented, individually or in clusters.

Sequencing and clustering should be determined by the following factors: (a) learners' age, (b) complexity of the material, (c) the ability to vary activities to meet the objective, and (d) the time required to complete the instructional tasks.

Note that Horton (2006) describes this process as spotting related objectives (pp. 23-25) and sequencing (bottom up, top down, sideways; pp. 27-31).
