Overview

A strategic service design and AI strategy project exploring how Bank of Georgia could reduce mortgage approval time by integrating an AI-assisted property valuation model into the existing process. The project spanned discovery research, stakeholder interviews, journey mapping, and service blueprinting — resulting in an 8-month implementation roadmap that targets a reduction in approval time from 9 business days to 5.

The core insight was that a single step — manual property valuation — accounts for more than half the total approval time. By replacing it with an Automated Valuation Model (AVM) for standard residential properties, the bank can dramatically accelerate processing while freeing licensed appraisers for complex, high-value cases where human judgement is genuinely needed.

My Role

Led the end-to-end service design process — from stakeholder interviews and journey mapping through to service blueprinting and roadmap development. Responsible for facilitating workshops, synthesizing insights, and translating findings into actionable proposals for a cross-functional team.

  • Planned and conducted stakeholder interviews across mortgage, compliance, and operations teams
  • Facilitated a cross-functional journey mapping workshop
  • Developed the AS-IS and TO-BE service blueprints
  • Built the problem prioritization framework and presented findings to leadership
  • Authored the 8-month implementation roadmap and change management plan

Stakeholder Interviews

Conducted interviews with mortgage specialists, branch managers, compliance officers, and licensed property appraisers to map the current-state process and surface operational bottlenecks. Key questions explored:

  • What slows down the approval process most — and where does the time actually go?
  • Where does manual effort create the biggest risk of error or inconsistency?
  • What data already exists in the bank's systems that isn't being fully used?
  • Where do customers drop off, complain, or become frustrated during the mortgage journey?
  • What operational constraints would shape any technology change?

Interviews were conducted with 12 participants across 5 roles. Sessions were recorded and synthesised into an affinity map highlighting themes around valuation delays, document chasing, and inconsistent communication with applicants.

Discovery — Journey Mapping Workshop

Facilitated a half-day cross-functional workshop with mortgage specialists, branch managers, a compliance officer, and a systems lead. The goal was to map the current mortgage application journey across three lenses simultaneously:

  • Customer experience: touchpoints, emotions, and pain points from initial enquiry through to approval and disbursement
  • Front-stage operations: branch interactions, digital channels, call-centre touchpoints, and relationship manager handoffs
  • Back-stage systems: credit scoring, document verification, property valuation, and legal checks

The workshop surfaced 14 distinct pain points. The property valuation step appeared across all three lenses as the most consistent blocker — slow for customers, expensive for the bank, and highly dependent on appraiser availability.

Problem Identification & Prioritization

Plotted all 14 pain points on an effort/impact matrix to identify where a focused intervention would deliver the greatest return. Five issues emerged as high-impact and low-to-medium effort:

  • Manual property valuation (3–5 day delay per application)
  • Applicant status updates — no proactive communication during processing
  • Document re-submission loops caused by unclear initial requirements
  • Duplicate data entry across mortgage origination and core banking systems
  • Appraiser scheduling bottleneck during peak periods

The property valuation step was selected as the primary focus: it was the largest single contributor to total approval time, it affected every application, and a viable technical solution (automated valuation models) was already proven in other markets.

The Problem

The current property valuation process is entirely manual. A licensed appraiser physically visits each property, prepares a written report, and submits it to the bank. This step takes 3–5 business days and is required for every mortgage application — regardless of property type, value, or complexity.

This creates three compounding problems:

  • Delay: Valuation accounts for more than half the 9-day average approval time, creating a bottleneck that no other process improvement can fully offset
  • Cost: Every appraisal carries a fee (borne by the applicant) and consumes internal coordination time
  • Inconsistency: Appraiser judgement varies; two appraisers assessing the same property can return meaningfully different valuations

Proposed Solution — AI-Assisted Automated Valuation Model

Introduce an Automated Valuation Model (AVM) that cross-references property registry data, recent comparable sales, and market trend signals to generate an instant initial valuation — eliminating the 3–5 day manual appraisal step for the majority of applications.

The model uses a tiered routing logic:

  • Standard residential properties within defined parameters (property type, value band, data confidence score): AVM output accepted directly; application proceeds immediately
  • Properties near thresholds or with lower data confidence: AVM output presented to a licensed appraiser for validation rather than origination — reducing their effort from a full visit to a desk review
  • Complex or high-value properties: Routed to full manual appraisal as before; AVM provides a reference figure only

This approach targets 70–80% AVM coverage for standard residential mortgages while preserving the human review layer for cases where model confidence is insufficient.

Service Blueprint

Created a detailed TO-BE service blueprint mapping the redesigned mortgage process across all layers of the service. The blueprint served as the primary alignment artefact for cross-functional discussions with technology, compliance, and operations teams.

Key blueprint layers:

  • Customer actions: digital application submission, document upload, instant AVM valuation confirmation, approval notification
  • Front-stage interactions: relationship manager touchpoints, AVM result communication, exception-handling communication for manual review cases
  • Back-stage system actions: AVM query triggered on submission, data enrichment from registry API, confidence scoring, routing logic, compliance logging
  • Supporting processes: model monitoring and drift detection, quarterly accuracy reviews, appraiser override workflow, regulatory audit trail

Risk Management & Governance

Regulatory Risk
AI valuations may not be accepted by the National Bank of Georgia · Mitigation: early regulator consultation; human review preserved for all edge cases
Data Quality Risk
Registry and market data may be incomplete or stale · Mitigation: data audit in Month 1; automatic fallback to manual appraisal where confidence score is low
Model Accuracy Risk
AVM predictions may diverge from actual property values · Mitigation: conservative thresholds in pilot; appraiser override always available; quarterly accuracy reviews
Change Management Risk
Mortgage specialists and appraisers may resist AI-assisted workflow · Mitigation: co-design sessions; AVM framed as decision support, not replacement

Pilot & Change Management

The pilot (Month 6) runs across 5 steps:

  1. Select 50 standard residential mortgage applications for the pilot cohort
  2. Run the AVM in parallel with the existing manual appraisal — compare outputs, not replace them
  3. Brief relationship managers and mortgage specialists on the new workflow ahead of go-live
  4. Track accuracy variance, processing time, and applicant satisfaction across both cohorts
  5. Hold a structured retrospective at end of Month 7 before proceeding to scale

After pilot sign-off, rollout is phased: starting with standard residential properties under a defined value threshold, expanding as the model's accuracy track record builds. Appraiser resource is redeployed to complex and commercial valuations — the work that genuinely requires physical inspection and professional judgement.

The proposed changes target a 44% reduction in average approval time — from 9 business days to 5 — by eliminating the manual appraisal step for 70–80% of standard residential applications. Appraiser capacity freed from routine valuations is redeployed to complex and commercial cases where specialist judgement genuinely adds value. The applicant experience improves through faster decisions and reduced uncertainty during the process.

Reflections

This project reinforced how service design and AI strategy complement each other when applied to operational transformation. The technical feasibility of an AVM was never the hard part — models like this have been running in other markets for years. The harder problem was designing the governance layer: when to trust the model, how to log decisions for regulatory compliance, and how to bring mortgage specialists along without creating resistance to a process that would change their role.

The service blueprint became the key alignment tool. It made the abstract concrete — showing every team member exactly where the AI touched the process, where a human remained in the loop, and what happened at every exception. Without it, the conversation stayed at the level of whether AI should be used at all; with it, the conversation shifted to how.

If I were to extend this work, the next step would be building a more granular data quality framework for the registry feed — the AVM is only as good as the data it's trained on, and the Georgian property registry has known gaps in recent transaction history for some regions.
