Pay grades and salary bands
The Ashewa 16-Grade compensation structure, Hay Group factor evaluation, 4-step progression bands, tier-based allowances, and merit matrix rules.
SmartERP incorporates a modern total compensation engine (smarterp_hr_grade) built upon an established 16-Grade Structure evaluated via the international Hay Group methodology.

The 16-Grade Architecture (hr.grade)#
The grade matrix categorizes every job position across five distinct career bands:
+----------------------------------------------------------------------------------------------------+
| THE ASHEWA 16-GRADE CAREER & COMPENSATION HIERARCHY |
+-------+--------------------+-----------------------------------+--------------------+--------------+
| Grade | Career Level | Typical Organizational Positions | Education Required | Experience |
+-------+--------------------+-----------------------------------+--------------------+--------------+
| G1 | Entry Operations | Office Assistant, Driver, Guard | 10th / 12th Grade | 0 β 1 Years |
| G2 | Junior Support | Junior Clerk, Custodian, Courier | TVET Level 2/3 | 1 β 2 Years |
| G3 | Operational Support| Cashier, Junior Data Clerk | TVET Level 4 | 2 β 3 Years |

Hay Group Factor Evaluation Methodology#
Every grade in SmartERP is calibrated using the three standard Hay Group evaluation factors:
- Know-How: Depth of specialized technical knowledge, managerial breadth, and required interpersonal human relations skills.
- Problem-Solving: The thinking environment (standardized vs. broadly defined) and thinking challenge (repetitive vs. creative innovation).
- Accountability: Freedom to act, job impact on corporate revenue, and direct magnitude of organizational financial authority.
Mathematical Formulation of Salary Bands#
Rather than maintaining arbitrary static salary tables, SmartERP calculates salary bands dynamically using an anchored Base, Coefficient, and Range Spread:
$$ ext{Band Midpoint} = ext{Band Base} imes ext{Coefficient}$$
$$ ext{Band Minimum} = \frac{ ext{Band Midpoint}}{1 + \left(\frac{ ext{Range Spread \%}}{2 imes 100} ight)}$$
$$ ext{Band Maximum} = ext{Band Minimum} imes \left(1 + \frac{ ext{Range Spread \%}}{100} ight)$$
Four-Step Intra-Grade Progression#
Within each grade, an employee progresses through four distinct compensation steps based on annual tenure and merit evaluations:
$$ ext{Step Interval} = \frac{ ext{Band Maximum} - ext{Band Minimum}}{3}$$
- Step 1 (Entry / Minimum): $ ext{Band Minimum}$
- Step 2 (Developing): $ ext{Band Minimum} + ext{Step Interval}$
- Step 3 (Proficient / Market Target): $ ext{Band Minimum} + (2 imes ext{Step Interval})$
- Step 4 (Senior / Maximum): $ ext{Band Maximum}$
Grade Salary Band Range Progression:
[================= Step 1 =================] Entry Level
[================= Step 2 =================] Developing Competence
[================= Step 3 =================] Fully Proficient (Midpoint)
[================= Step 4 =================] Maximum Ceiling
Tier-Based Allowance Rules#
SmartERP groups the 16 grades into four organizational benefit tiers, defining default monthly allowance entitlements:
| Grade Tier | Included Grades | Housing Allowance (housing_allowance_amt) | Representation Allowance (representation_allowance_amt) | Transport Policy |
|---|---|---|---|---|
| Tier 1 (Support) | G1 β G5 | Standard Grade Default | ETB 0.00 (Not Applicable) | Commuter Shuttle or Directive 1/2011 Allowance |
| Tier 2 (Professional) | G6 β G10 | Mid-Level Allowance | ETB 0.00 (Not Applicable) | Standard Transport Allowance |
| Tier 3 (Management) | G11 β G13 | Senior Management Band | Tier 3 Representation Allowance | Transport Allowance / Assigned Vehicle |
| Tier 4 (Executive) | G14 β G16 | Executive Housing Band | Tier 4 Executive Representation | Executive Vehicle & Fuel Allowance |
Merit Progression Matrix (hr.merit.plan)#
Annual step increases are determined by a merit matrix combining the employee's performance rating with their current position within the salary band:
| Performance Rating | Current Band Step: Step 1 | Current Band Step: Step 2 | Current Band Step: Step 3 | Current Band Step: Step 4 |
|---|---|---|---|---|
| 5 - Exceptional | Advance 2 Steps | Advance 2 Steps | Advance 1 Step to Step 4 | One-off Merit Bonus |
| 4 - Exceeds Expectations | Advance 1 Step | Advance 1 Step | Advance 1 Step | One-off Merit Bonus |
| 3 - Meets Expectations | Advance 1 Step | Advance 1 Step | Maintain Current Step | Maintain Current Step |
| 2 - Needs Improvement | Freeze Step | Freeze Step | Freeze Step | Freeze Step |
| 1 - Unsatisfactory | Performance Plan | Performance Plan | Performance Plan | Performance Plan |
