SDI and ECR Full Critical Comparison
This independent research briefing (July 2026) provides a full exposition of the Strength Deployment Inventory (SDI 2.0) and a systematic, construct‑level comparison with the Emotional Capital Report (ECR). It begins with an executive judgement that positions SDI as a highly usable relationship‑development tool that excels at explaining motives and conflict dynamics, while ECR is a broader, norm‑referenced assessment of ten emotional and social competencies for leadership. The briefing details SDI’s theoretical lineage (Porter’s Relationship Awareness Theory), its three‑colour motive system (Blue‑People, Red‑Performance, Green‑Process), the seven Motivational Value Systems (including the balanced Hub), and the 13 conflict‑sequence patterns that map motive shifts under threat. It explains the 28 productive strengths and their over‑done counterparts, the scoring architecture (triangular coordinate scores, ipsative ranking), and the evidence base (developer‑reported reliability, test‑retest, and critical limitations such as reliance on self‑report and modest independent validation). Practical applications of SDI (team development, conflict resolution, coaching, selection) are outlined with associated risks. The ECR is described as a norm‑referenced, 360‑capable emotional intelligence instrument measuring competencies such as Self‑Knowing, Empathy, Self‑Control, and Optimism, with published psychometric support. A detailed side‑by‑side comparison across dimensions (construct, measurement level, conflict handling, strengths logic, 360 feedback, response bias, research base) highlights where each tool is stronger and where caution is needed. Construct‑level mapping links SDI colours and conflict motives to ECR competencies, clarifying that high motive scores do not equate to high emotional capability. The briefing recommends an integrated workflow: use SDI to create shared motive language and identify conflict sequences, then apply ECR (or ECR 360) to assess the emotional resources needed to enact those motives constructively, followed by coaching and repeated behavioural measurement. The final assessment affirms SDI’s longevity for relational insight while noting its psychometric limits, and positions ECR as the more robust tool for leadership competency benchmarking, provided it is used alongside other selection methods.

Executive Judgement: Positioning SDI and ECR
A concise appraisal that frames SDI as a relationship‑development instrument with a unique conflict focus, and ECR as a comprehensive emotional‑competency assessment for leadership.
