ABSTRACT ' .. 200 wo..s)This monograph addresses a fundamental problem inoperational level cbmmand. The operational commander is required by Army andJoint publications to organize his forces. In order to do this, the commandermust understand the limits of his span of control when making his organizationaldecisions.

4 The term span of control is neither defined nor explained in the armyand joint publications. At the tactical level, the span of control isestablished in the applicable TO&Es. At the operational level, this is not thecase. The variables that affect civilian span of control were examined in amilitary context. These factors are personality and organizational driven. Thefactors that have the greatest affect on span of control are similarity offunction of subordinates, style of control the commander uses, the type ofcoordination required between subordinates, and the number of personal contactsthe commander uses to control his forces. In addition, changes in structure,tasks and personnel will affect span of control over time.

Pierce, USA, 52 study examines the issue of span of control for anoperational commander. The operational commander Is required by Jointand Army doctrine to organize his forces. In order to do so, he mustunderstand the limits of his span of control when makingorganizational of control Is not defined In either Army or Jointpublications, but the term Is used In doctrinal manuals.

7 At thetactical level, a span of control between two and five units Isbelieved to be appropriate. However, the commander's span of controlat tactical levels Is much larger when CS, CSS and staff areconsidered. At the operational level, understanding what affects spanof-control Is essential. For subunifled commands, Joint task forceorganizations, field armies or army groups, the operational commandermust establish his own organization, Nowhere In doctrine Is amethodology for doing this the military does not define span of control, there Is awealth of Information on It In management books. This treatment wasexamined In a military context. The factors that have the mostInfluence on the coumander's span of control are the similarity offunction of the subordinates, the style of control of the commander,the type of coordination between the commander and his subordinates,and the number of personal contacts that the commander uses In hiscommand style.

8 Changes In the structure, tasks, and personnel willalso affect the limits of span of control over time. Unfortunately,understanding the factors that Influence span of control will not helpa commander establish his Inltial span of control. They will onlyhelp him adJust his span of control given a number of subordinates anda situation. Thus, two to five subordinates appear to be a goodstarting place when the commander organizes his forces. Then, thecommander must adjust his span of control based on the are three major doctrinal implications in this study. TheArmy and Joint doctrine provides no Information on how to organizeforces -only that It must be done. This doctrinal void must befilled In future publications.

9 The second Is the criticality ofreducing the amount of Information the commander Is presented duringbattle. The commander must establish a Commander's CriticalInformation Requirements (CCIR) and this list should be added to allcampaign plans. This will ensure that all subordinate elements focuson what the commander needs to make his decisions. This will help thecomnander expand his rpan of control. Finally, the military educatlunsystem must Inculcate In all officers the philosophy and traits thatfoster decentralized control. This Is the primary factor that willenable a commander to expand his span of of ContentsSI. Introduction ..Il. Span of Control Doctrine .. 4 III. Span of Control Theory -A Civilian 14IV.
