```

### 2.2 Gap-Analysis Inputs

This workflow depends on prior workflow outputs:
- T-DMM maturity-assessment report
- Business-research results (BRD)
- IT systems & data inventory report

---

## III. Detailed Steps

---

### Step 1: Target Baseline Definition

**Goal**: Establish a clear comparison baseline (To-Be target state) for the gap analysis.

**Inputs**: Industry standards / regulations, benchmark cases, business needs
**Outputs**: Target-baseline document, benchmarking KPI system

**Guidance:**

**1.1 Three-dimensional target baseline**

```
Target-baseline construction:

+---------------------------------------------------------------+
|  Strategy benchmark  | Industry benchmark | Requirement benchmark|
|  (Policy)           | (Benchmark)        | (Requirement)        |
+---------------------+--------------------+---------------------+
| National transport  | Leading peer       | Client business goals|
| development strategy|  practices         | Client KPI targets   |
| Digital-transport   | Comparable-city    | Business-unit expects|
|  plan              |  benchmarks        | User real needs      |
| Regional plan      | Gartner IT trends  |                     |
| Sector regulations | Consultancy maturity|                    |
+---------------------------------------------------------------+
```

**1.2 Transport benchmarking KPI system**

| Category | Key metric | Advanced reference | Client current | Gap |
|---------|---------|:---------:|:-----:|:---:|
| Network monitoring | Auto incident-detection rate | >85% | | |
| Emergency response | Avg. response time (min) | <15 min | | |
| Maintenance | Auto defect-ID rate | >80% | | |
| Tolling ops | ETC pass-through rate | >99.5% | | |
| Public service | Info-publish timeliness | >95% | | |
| Data governance | Core-data accuracy | >99% | | |
| System availability | Core-system uptime | >99.9% | | |
| Cybersecurity | Classification-compliance rate | 100% | | |

---

### Step 2: Multi-Dimensional Gap Comparison

**Goal**: Systematically identify all gaps between current state and target.

**Inputs**: Current-state report (As-Is), target baseline (To-Be)
**Outputs**: Gap landscape, quantified gap table, gap heat map

**Guidance:**

**2.1 Six-dimension gap framework**

```
 Dimension        Analysis                         Key question
┌────────┐  ┌──────────────────┐  ┌─────────────────────────┐
│Strategy│  │ Digital-strategy  │  │ Has a plan? Does it land?│
│ gap    │  │  completeness     │  │ How much invested? Enough?│
├────────┤  ├──────────────────┤  ├─────────────────────────┤
│Business│  │ Online coverage    │  │ How much still offline?  │
│ gap    │  │ Intelligence level│  │ Is AI actually used?      │
├────────┤  ├──────────────────┤  ├─────────────────────────┤
│Data gap│  │ Governance maturity│  │ Is data usable? Good?    │
│        │  │ Value realization  │  │ Data-driven decisions?   │
├────────┤  ├──────────────────┤  ├─────────────────────────┤
│Tech gap│  │ Architecture modern│  │ Architecture modern?     │
│        │  │ Infra elasticity   │  │ Supports 3-yr growth?    │
├────────┤  ├──────────────────┤  ├─────────────────────────┤
│Org gap │  │ Digital talent mix │  │ Anyone who gets AI?      │
│        │  │ Digital-culture mat│  │ Embrace or resist?       │
├────────┤  ├──────────────────┤  ├─────────────────────────┤
│Sec gap │  │ Cyber-defense cap. │  │ Defense matches risk?    │
│        │  │ Compliance level   │  │ Passed classification?   │
└────────┘  └──────────────────┘  └─────────────────────────┘
```

**2.2 Gap-quantification method**

Each gap quantifies three indicators:

| Dimension | Calculation | Example |
|---------|---------|------|
| Gap magnitude | Target − current | Incident-detection: 85% − 30% = 55% gap |
| Impact degree | Business metric × weight | Causes X missed-alarm incidents/yr, $Y loss |
| Closure difficulty | 1–5 (1 easiest, 5 hardest) | Tech complexity + org resistance + funding |

**2.3 Gap heat map**

```
Gap heat map example:

            Strategy Business Data Tech Org Security
         +─────+─────+─────+─────+─────+─────+
Regulations│ 🟡  │ 🟡  │ 🟡  │ 🟢  │ 🟢  │ 🟢  │
         +─────+─────+─────+─────+─────+─────+
Benchmarks │ 🔴  │ 🔴  │ 🔴  │ 🟡  │ 🔴  │ 🟡  │
         +─────+─────+─────+─────+─────+─────+
Needs      │ 🟡  │ 🔴  │ 🔴  │ 🟡  │ 🟡  │ 🟡  │

 🔴 Major gap (>50%)  🟡 Clear gap (20–50%)  🟢 Minor gap (<20%)
```

---

### Step 3: Root-Cause Analysis and Diagnosis

**Goal**: Identify the deep causes behind each key gap, not just surface symptoms.

**Inputs**: Gap list, interview records, inventory data
**Outputs**: Root-cause report, causal-chain diagram

**Guidance:**

**3.1 5-Why example**

```
Problem: Maintenance decisions lack data support

Why 1: Why no data support?
 → No usable pavement-performance data

Why 2: Why no usable pavement-performance data?
 → Inspection data is all on paper

Why 3: Why is inspection data on paper?
 → Existing system has no mobile-data entry

Why 4: Why doesn't the system support it?
 → System built in 2015, no mobile design

Why 5: Why not upgrade or replace?
 → No budget to start (change resistance / low tech capability / ...)

Root cause: Weak investment-ops framework + legacy systems + low tech capability
```

**3.2 Fishbone analysis**

```
                     +------------------+
                     |   Poor data quality│
                     +--------+---------+
                +-----------+-----------+
                |           |           |
         +------+------+ +---+---+ +-----+------+
         | No data std | |No gov.| |Heavy manual |
         |             | |tool   | |entry, no    |
         |             | |       | |validation   |
         +-------------+ +-------+ +-------------+
```

**3.3 Root-cause taxonomy**

| Category | Description | Example |
|---------|------|------|
| Missing institution | No corresponding policy / process | No data-management policy |
| Org defect | No corresponding org / role | No dedicated data analyst |
| Underfunding | Budget insufficient / not planned | Security-equipment budget cut |
| Tech debt | Historical tech choice limits now | Monolith can't scale |
| Talent gap | Lacks key-skill talent | No AI / big-data talent |
| Culture resistance | Culture unfriendly to innovation | Business resists data sharing |
| External constraint | Regulations / compliance / supply chain | Tech-sovereignty / local-content mandate incomplete |

---

### Step 4: Improvement-Opportunity Identification and Ranking

**Goal**: Convert gaps into executable improvement opportunities and rank them scientifically.

**Inputs**: Gap list, root-cause analysis, resource constraints
**Outputs**: Opportunity list, opportunity-priority matrix

**Guidance:**

**4.1 Three elements of every opportunity**

Each opportunity must include:
1. **Which gap it solves** — maps to which gap
2. **What to do** — concrete improvement measure
3. **How** — rough implementation path

**4.2 Opportunity evaluation model (ICEBERG)**

| Dimension | Weight | Description |
|------|:---:|------|
| **I**mpact | 30% | Lift to core business metrics |
| **C**ost | 20% | Funding & labor needed (lower better) |
| **E**ase | 15% | Tech & org implementation difficulty (lower better) |
| **B**enefit | 20% | Expected economic / social / safety benefit |
| **E**mergency | 10% | Regulatory / compliance / risk urgency |
| **R**isk | 5% | Implementation risk (lower better) |
| **G**rowth | 5% | Support for future development |

**Composite opportunity score = Σ(dimension score × weight)**

**4.3 Opportunity priority matrix**

```
               High value
                   ↑
                   │
     P1 Do now     │ P2 Plan key
   (Quick Wins)    │ (Strategic Bets)
                   │
   ────────────────┼──────────────→
   Low investment  │       High investment
                   │
     P3 Opportun.  │ P4 Long-term
   (Low Hanging)   │ (Big Rocks)
                   │
                   ↓ Low value
```

---

### Step 5: Quick-Win Identification and Validation

**Goal**: From opportunities, identify those that pay off fast (1–3 mo) to build confidence and consensus.

**Inputs**: Opportunity list, resource assessment
**Outputs**: Quick-win list, quick-win validation plan

**Guidance:**

**5.1 Quick-win criteria**

| Criterion | Requirement |
|------|------|
| Horizon | Visible initial result within 1–3 months |
| Investment | No large new budget (or within budget) |
| Dependencies | Few dependencies on other system changes |
| Visibility | Result directly perceivable by mgmt & business |
| Risk | Low tech risk, no core-business interruption |
| Extensibility | Runs standalone, extendable later |

**5.2 Typical transport quick wins**

| Quick win | Content | Horizon | Visible effect |
|---------|------|:---:|---------|
| Executive dashboard | Integrate existing data into a decision cockpit | 1–2 mo | See global status at a glance |
| Mobile inspection app | Replace paper inspection | 2–3 mo | Inspection efficiency +50% |
| Auto-reporting | Replace manual Excel roll-up | 1–2 mo | Save hours of weekly work |
| AI vision pilot | Deploy AI recognition in 1–2 scenes | 2–3 mo | See real AI effect |
| Data-quality campaign | Focus 1–2 core tables | 1–2 mo | Clear accuracy uplift |

**5.3 Quick-win validation**

Run a PoC on each quick win:
- Pick a representative scenario
- Implement a minimal viable product (MVP) fast
- Run in the real environment 1–2 weeks
- Collect usage data and user feedback
- Decide whether to scale

---

### Step 6: Gap-Analysis Report Authoring

**Goal**: Consolidate all gap-analysis results into a complete report.

**Inputs**: Gap list, root-cause analysis, opportunities, quick wins
**Outputs**: Gap-analysis & opportunity report

**Guidance:**

---

### Step 7: Improvement-Roadmap Authoring

**Goal**: Convert opportunities into a phased roadmap with schedule and resource needs.

**Inputs**: Gap-analysis report, opportunity ranking, client constraints
**Outputs**: Preliminary roadmap, resource estimate

**Guidance**: See [Phase 03 Step 4 (3-Year Roadmap & Investment Plan)](../phase-03-strategy-and-top-level-design/04-three-year-roadmap-and-investment-workflow.md).

---

### Step 8: Consensus Building and Launch

**Goal**: Get client management to accept the gap conclusions and approve the first batch of improvements.

**Inputs**: Gap-analysis report, improvement roadmap
**Outputs**: Management acceptance minutes, first quick-win launch

**Guidance:**

**8.1 Presentation strategy**

- Emphasize "impact of the problem" not "description of the problem"
- Let data speak: quantify impact per gap
- Visualize benchmarking: radar comparison vs. benchmark
- Clear path: explicit "do this first, then that"
- First session: don't dump the full roadmap; lead with quick wins + 3-month plan

**8.2 Keys to securing commitment**

- Let the client say "yes, this really needs fixing"
- Quick wins designed so the client feels "low investment, fast payoff"
- Cite peer-city success cases as endorsement
- Stress "what not to do" and the consequences of inaction

## VIII. Common Pitfalls and Countermeasures

| # | Pitfall | Countermeasure |
|---|------|------|
| 1 | "Everything is a problem" loses focus | Focus on Top 10–15 key gaps |
| 2 | Root cause stays surface ("system too old") | 5-Why to institution / org / funding layer |
| 3 | Opportunities ignore client constraints | Know real budget, time, org constraints |
| 4 | Ignores "what not to do" | Explicitly list "defer" or "do not do" |
| 5 | Quick win becomes placebo | Must solve a real problem, create real value |
| 6 | Report too long to read | Exec summary ≤2 pages, conclusions first |
