Force Employment Seminar Wargame Series • Seminar wargame format • 5 days and 45 participants • Detailed scenarios, vignettes and forces • Joint Conflict and Tactical Simulation (JCATS) for situational awareness • STAMPER • Structures judgments and insights sessions
HEAVY FEATHERS RABBIT REDUX WILD HONEY LEATHER STOCKINGS X HERA Baku MEDUSA WILD HONEY Gormanskaya APHRODITE HEAVY FEATHERS Traditional Combat in Open Complex Terrain (but not urban) Urban Operations
OR Roles and Objectives • Role: • Problem definition, guidance, data collection and analysis, presentation of results • Objectives: • Develop a comprehensive and robust methodology to measure performance and evaluate risk factors • Present results in a clear concise manner to be briefed to decision-makers
Special Considerations • Imperfect knowledge of models, equipment, structures, particularly for the Interim Army • Transient nature of the wargaming teams • Nature of the seminar wargame - hidden complexity in the verbal interplay • Multiple levels participation
Analysis plan – Two Tier Approach • Quantitative • STAMPER • Qualitative • Observation Sheets • Strengths/ Weaknesses/ Issues Sheets • Judgment & Insights Sessions
STAMPER – Systematic Task Analysis for Measuring Performance and Evaluating Risk • Development of the DGLCD Task Lists • Development of Survey Instruments • Ratings rolled-up for overall performance per operational function, and evaluation of risk • Interpretation of results • Comparison of results from one seminar to another
DGLCD Task Lists • Developed by Combat Developers and assessment teams • Comprehensive list of tasks per Operational Function: Command, Sense, Act, Shield and Sustain • Level 1, Level 2 and Level 3 Tasks
DGLCD Task Lists • Client-analyst collaboration was key • Process: Iterative “straw man” approach • Benefits: • Engagement of participants – sense of ownership • Constant review and refinement • Synergies achieved
Survey Instruments • Based on the DGLCD Task Lists • One EXCEL based survey instrument per operational function • Assessors asked to rate tasks along two dimensions: • Performance • Impact/Importance
Survey Instruments… Survey Questions Response Options List of tasks Assessor’s responses for all 6 vignettes
Performance Measurement The simple model… Performance score of a task = weighted average of the performance scores of the tasks belonging to it. For example: The performance of a Level 2 task is the weighted sum of the performance scores of the Level 3 tasks that make up that Level 2 task.
Assessment of Risk For Level 3 tasks only… • Low score = higher risk • Color-coded for visual cuing • Numerical values for ranking
Automated Tool Risk Performance
Strengths • Client/analyst collaboration • Structured evaluation of performance for combat developers • Confirmation of seminar discussion results • Visualization of results • Colour-coding and graphs • Quick identification of performance/risk deltas • Near real-time results • Available for discussion at end-of-day J&I • Clarification of remaining issues
Caution… • Should not compare results across op functions • Within operational function • Across scenarios/vignettes (e.g. open vs. urban) • Across capability sets (i.e. across seminar wargames) • Deltas should be used as indicators, pointers to an underlying phenomenon requiring investigation • Results to be interpreted along with qualitative results
Abusing the Simple Model Ex. 1 Assuming all tasks are performed at an acceptable level Ex. 2 Assuming equal improvement/ investment across operational functions
Concluding Remarks • Seminar wargame format appropriate for scope of investigation • Complimentary data collection methodologies: quantitative and qualitative (STAMPER) provided complete picture • STAMPER • Met the objectives: consistent, repeatable, and simple • Structured evaluation • Good communications tool • Results should be interpreted with caution • Provided an indication of performance/risk to a level deemed appropriate, and not beyond

Survey Instrument Questions Question 1: Performance Given your experience and the discussions held during the seminar wargame, please indicate the level of overall performance you believe we would most likely achieve in the completion of this task during this mission, given the capability-set assumed for this seminar wargame.
Survey Instrument Questions Question 2: Impact For this particular mission, how would you characterize the impact or importance of this task in the overall performance of the higher-level task it belongs to.
Point Allocation Matrix Assessor Response to Question 1 Assessor Response to Question 2 Score = Sum of points Sum of weights
Example 4. Distribution of Sense L3 Scores For Level 3 Tasks: Q1 results Q2 results
Sponsor Objectives • To assess/measure the impact of changes in structures, equipment and capabilities that will come into effect during the Interim Army timeframe with a view to further refining the force employment concept in preparation for field trials at Canadian Manoeuvre Training Centre and eventual incorporation into doctrine • To identify and prioritize discrete issues requiring additional analysis and to direct the examination of these spin-off activities to the appropriate organization
Level 2 Tasks Level 1 Tasks Operational Function Survey Instruments Responses Provided by Assessors Question 1: Performance Derived from the Roll-Up Level 3 Tasks Question 2: Impact Level 3 Tasks Level 2 Tasks Level 1 Tasks
Future Development • Refinement of DGLCD Task Lists • Refinement of weights using techniques such as ranking, pair-wise comparison, etc. • Increase number of surveys collected – statistical analysis • Hand-held data entry devices for instantaneous collection of surveys
Abusing the Simple Model Ex. 3 Assuming improvement in Command exceeds improvement in other operational function; basing investment decisions on this
