Additives

Understanding Product Additives

Additives in timveroOS detail credit product parameters regarding conditions and collateralization. They serve as the mechanism for creating product variations within a single credit product framework, enabling sophisticated segmentation and pricing strategies.

Core Additive Concepts

According to the system architecture, additives:

Define specific lending conditions within a credit product
Contain algorithms (scripts) for calculating offers to participants
Operate at various business process stages
Enforce strict correspondence: one offer per participant per additive

The credit score analysis logic and eligibility determination occur at the algorithm (script) level specified in each additive. If conditions aren't met, no offer is generated within that additive.

Relationship to Credit Products

Credit products serve as aggregating entities for additives. This architecture provides:

Single product definition with multiple variations
Centralized maintenance with distributed execution
Consistent base parameters with flexible segmentation
Simplified product portfolio management

Without active additives, credit products don't participate in the origination process, highlighting the critical role additives play in operationalizing lending offerings.

Practical Implementation Example

The system documentation provides this illustrative example:

Base Credit Product: Personal Loan

Amount range: 1,000-20,000 euros
Term range: 12-36 months
General consumer lending purpose

Three Configured Additives:

Additive 1: Basic Tier

Term: 12-month lending only
Amount: 1,000-3,000 euros
Rate: 10% annual interest
Condition: Participant credit score below 650
Logic: Algorithm evaluates score and generates offer only if criteria met

Additive 2: Standard Tier

Term: 12-36 month lending
Amount: 1,000-7,000 euros
Rate: 7% annual interest
Condition: Participant credit score 650 or above
Logic: Higher score enables better terms

Additive 3: Premium Tier

Term: 12-36 month lending
Amount: 5,000+ euros
Rate: 5% annual interest
Condition: Collateral required
Logic: Security enables expanded lending

Configuration Components

Algorithm Implementation

Each additive specifies an offer script that:

Evaluates participant profiles
Applies business rules
Calculates eligible offers
Returns offer parameters or null

Offer Generation Rules

The system enforces:

One participant can receive offers from multiple additives
Each additive generates maximum one offer per participant
Offers aggregate at the credit product level
Final terms depend on participant selection

Integration Points

Additives integrate with:

Offer Engine: Executes pricing algorithms
Participant Profiles: Provides input data
Business Process: Determines execution timing
Credit Products: Inherits base parameters

Configuration Process

Prerequisites

Before creating additives:

Credit product must be defined
Offer scripts must be configured in Offer Engine
Participant profile attributes must be available
Business process integration points identified

Setup Steps

Step 1: Define Additive Parameters

Set specific term ranges
Configure amount limits
Establish base pricing
Define special conditions

Step 2: Configure Offer Script

Link to Offer Engine script
Map input parameters
Set calculation logic
Define output format

Step 3: Establish Eligibility

Set participant criteria
Configure security requirements
Define exclusion rules
Specify valid statuses

Step 4: Test and Validate

Run test scenarios
Verify calculations
Check edge cases
Confirm integration

Implementation Patterns

Based on system capabilities, additives enable:

Participant Role Support

The system calculates offers for participants with any role:

Borrower participants receive primary offers
Guarantor participants determine maximum limits
Combined assessment affects final terms
Script logic embeds role-based calculations

Multi-Additive Scenarios

Within one credit product:

Multiple additives can evaluate same participant
Each additive generates maximum one offer
Participant may qualify for several additives
Final selection from available options

Collateral Integration

As documented in the Premium Tier example:

Additives can require specific security
Collateral presence enables different terms
Security evaluation affects offer generation
Integration with collateral management

Version Management

When editing products with additives:

New product versions require new additives
Existing additives don't transfer automatically
Each version maintains separate additive sets
Active management prevents configuration gaps

Key Configuration Considerations

System Requirements

As documented, proper additive function requires:

Active additives for credit product participation
Configured offer scripts in Offer Engine
Available participant profile attributes
Defined business process integration points
