Efforts in the past to establish interoperability among relevant actionable actors, common operational terminology, and harmonization of respective operational procedures have not yielded the desired results so far. The harmonization of all relevant operational procedures (including their necessary corresponding data) executed by the actionable actors involved in a complex mission can be attained by identifying essential intermediate objectives. These objectives are crucial in achieving the final goal of the mission. A mission-planning algorithm has been created, where the mission underwent thematic decomposition. According to this technique, the mission was divided into smaller segments based on designer operational criteria, which are termed fundamental mission segments. In these segments, operational procedures take place and there are intermediate objectives. The completion of these intermediate objectives also means the completion of the corresponding mission segment. The completion of all mission sub-segments leads to the completion of the entire mission. It is worth mentioning that the mission segments are selected by an operational mission designer according to his experience based on the time needed for mission completion and logical thematic mission analysis. The algorithm's steps are as follows:  
* _Step 1: Creation of a list of fundamental mission segments_ In the mission design phase, each mission is divided into fundamental mission segments to ensure functional and operational manageability, employing appropriately selected segment lengths. This technique, known in engineering terminology as \"divide and conquer\", allows for effective thematic mission sub-divisions [53]. It is crucial for each sub-division to account for any temporal or spatial constraints that might influence the lengths of these fundamental segments. * _Step 2: Creation of a list of points of interest_ Points of Interest (POIs) are defined within each fundamental mission segment for operational planning reasons because their completion leads to the success of the mission. POIs are preplanned and considered of high priority because of the necessity for specialized handling and specific operational scrutiny during mission design and execution. POIs are selected at the discretion of the officials of the plan and are primarily map related; however, they might also encompass the concept of time or carry a logical interpretation and usefulness. These POIs necessitate the investigation of operational procedures, e.g., communication, mission criteria, conditions, situational awareness, record log files, etc. The number of POIs depends on the operation designer executive's capability to decide with operational accuracy in order to achieve successful mission completion. In a sense, POIs can also be referred to as transition nodes. Before and upon them, the appropriate operational actions should be executed effectively throughout the mission. These actions are related to the mission's success status, namely the total completion of the mission, the possibility of partial failure, and the potential abortion of the mission if demanded by the circumstances. * _Step 3: Creation of a list of fundamental mission segments with their POIs._ This list is created by the outcomes of step 1 and step 2. * _Step 4: Creation of two iterative procedures, defined as external and internal loops._ The use of the fundamental mission segments and POIs leads to a novel algorithm characterized by two iterative procedures, one of which (referred as internal, \"In\") is nested within the other (referred as external, \"Ex\"):  
1. The _external iterative procedure_ (Ex-loop) involves transitioning from the beginning of each fundamental mission segment to the beginning of the next. 2. The _internal iterative procedure_ (In-loop), nested within the external iterative procedure, involves transitioning from one POI to another within each fundamental mission segment.
