1-27. Depending on the echelon, all activities of the operations process can occur simultaneously within a headquarters. Divisions and corps headquarters are staffed with a plans cell, a future operations cell, and a current operations integration cell. These headquarters can plan, prepare, execute, and assess operations simultaneously, cycling through multiple iterations of the operations process. Companies however, tend to move sequentially through the activities of the operations process because they lack a staff. A company commander receives the mission and conducts troop leading procedures (TLP). After developing the plan, the company commander conducts rehearsals and supervises preparation prior to execution. The company then executes its mission while continuously assessing. Following execution, the company consolidates and reorganizes in preparation of a new mission starting a new cycle of the operations process.
