1. Talent Optimisation: Precise role-skill matching increases productivity by 34%

2. Competitive Differentiation: Superior data capabilities drive 23% higher revenue growth

3. Risk Mitigation: Objective evaluation reduces critical skill gaps by 61%

3. Framework Overview

The Five-Tier Proficiency Ladder

Our framework employs a standardised five-tier proficiency scale that provides clear progression pathways:

Persona-Based Requirements

Different roles require distinct proficiency combinations:

Senior Data Engineer Profile:

• SQL: Tier 4 (Expert)

• Python: Tier 4 (Expert)

• Cloud Platforms: Tier 4 (Expert)

• Spark: Tier 4 (Expert)

• ML Fundamentals: Tier 2 (Intermediate)

Data Scientist Level 2 Profile:

• Python: Tier 3 (Advanced)

• Statistics: Tier 4 (Expert)

• Machine Learning: Tier 3 (Advanced)

• SQL: Tier 2 (Intermediate)

• Visualization: Tier 3 (Advanced)

Scoring Mechanism

The framework transforms individual skill component scores (0-10 scale) into tier classifications:

• Component Proficiency Threshold: 7.0/10 (70%)

• Tier Achievement Threshold: 80% of components must meet proficiency

• Progressive Validation: Each tier builds upon the previous tier capabilities

4. Methodology

Step 1: Skill Decomposition

Each technical skill undergoes systematic decomposition into tier-aligned components:

Example: SQL Skill Decomposition

Step 2: Component Classification

Components are classified into three evaluation categories:

1. Standard Evaluation Components (Green)

   1. Core capabilities evaluated through structured methods

   2. Typically, 70-80% of the total components

2. Excluded Components (Red)

   1. Elements outside the current evaluation scope

   2. Often, due to time constraints or strategic focus

3. Alternative Evaluation Components (Purple)

   1. Skills verified through certifications or separate processes

   2. Typically, 10-15% of components

Step 3: Scoring Protocol

Each component receives objective scoring:

Scoring Scale:

• 0-3:  Minimal understanding (Significant guidance required)

• 4-6:  Basic understanding (Occasional guidance needed)

• 7-8:  Solid understanding (Independent application)

• 9-10: Comprehensive understanding (Optimization capability)

Proficiency Threshold: ≥7.0 (Usually defined by organizations.)

Step 4: Tier Mapping Algorithm

The tier determination follows a progressive validation approach:

For each Tier (1 through 5):

• Count total components (n)

• Count proficient components (p) where score ≥ 7

• Calculate proficiency percentage: (p/n) × 100

• IF percentage ≥ 80% THEN tier achieved

• ELSE maximum tier = previous tier

Step 5: Role Readiness Determination

Binary readiness evaluation against role requirements:

IF all_required_skills_meet_tier_requirements:

  Status = "Role Ready"

  Output = Detailed capability profile

ELSE:

  Status = "Development Required"

  Output = Precision gap analysis + L&D recommendations
