1. Tiếp cận đề

Assignment 1 của OMGT2321 yêu cầu bạn phân tích quality và service operations của một service business (bệnh viện, ngân hàng, khách sạn, restaurant chain, e-commerce, education provider). Đề bài thường focus: (1) diagnose service quality gaps, (2) apply quality management frameworks, (3) recommend operational improvements.

Service operations khác manufacturing operations ở 4 đặc tính (IHIP):

  • Intangibility: service không thể touch hoặc see trước consumption
  • Heterogeneity: mỗi service encounter khác nhau (do human element)
  • Inseparability: production và consumption đồng thời
  • Perishability: không thể inventory service capacity

Những đặc tính này tạo ra unique challenges cho quality management. HD papers explicitly address IHIP throughout analysis, không treat services như manufacturing.

Cấu trúc bài bao gồm:

  • Service blueprint mapping
  • Quality assessment với SERVQUAL
  • Gap analysis (Parasuraman 5-Gap Model)
  • Process improvement (Lean, Six Sigma)
  • Capacity và demand management
  • Recommendations

  • Operational metrics (throughput, capacity, utilization)

Section 2: Service Blueprint

  • Map customer journey với touchpoints
  • Frontstage actions (visible to customer)
  • Backstage actions (invisible support)
  • Support processes
  • Lines of interaction, visibility, internal interaction
  • Failure points và wait points identified

Section 3: Service Quality Assessment

  • SERVQUAL framework: measure 5 dimensions (Tangibles, Reliability, Responsiveness, Assurance, Empathy)
  • Customer expectations vs perceptions gap
  • Survey data hoặc proxy metrics (NPS, CSAT, online reviews)
  • Benchmark vs competitors

Section 4: Gap Analysis (Parasuraman Model)

  • Gap 1: Customer expectations vs Management perceptions
  • Gap 2: Management perceptions vs Service quality specs
  • Gap 3: Service quality specs vs Service delivery
  • Gap 4: Service delivery vs External communications
  • Gap 5: Customer expectations vs Customer perceptions (the experiential gap)
  • Identify primary gap(s) driving issues

Section 5: Operations Improvement

  • Lean service: identify waste in service processes (waiting, defects, overprocessing, motion)
  • Six Sigma DMAIC: apply to specific service process
  • Theory of Constraints: identify bottleneck, exploit, subordinate, elevate
  • Capacity management: chase demand vs level capacity strategies
  • Yield management: price/capacity optimization (relevant for hotels, airlines)

Section 6: Recommendations

  • 3-5 prioritized initiatives
  • Each: scope, cost, expected impact (quality + cost + customer satisfaction)
  • Implementation timeline
  • Change management considerations (employee training, customer communication)

3. Theory cần nắm

SERVQUAL (Parasuraman, Zeithaml, Berry)

5 dimensions of service quality: Tangibles (physical evidence), Reliability (consistent delivery), Responsiveness (willingness to help), Assurance (knowledge và courtesy), Empathy (caring attention). RATER acronym (Reliability, Assurance, Tangibles, Empathy, Responsiveness). Survey instrument: 22 paired items measuring expectations và perceptions. Score = Perception - Expectation. Negative score = service quality gap. Reliability typically most important dimension (35-40% weight in customer evaluation).

5-Gap Model (Parasuraman)

Gap 1: knowledge gap (don't know what customers want). Gap 2: standards gap (know but don't translate to specs). Gap 3: delivery gap (specs exist but not delivered). Gap 4: communication gap (overpromise externally). Gap 5: experiential gap (customer's overall perception vs expectation, function of Gaps 1-4). Diagnose which gap dominant để target intervention. VD: NPS low and complaints about wait times → Gap 3 (delivery), focus on capacity và process improvements.

Service Blueprint (Shostack)

Visual map của service process across 4 horizontal layers separated by 3 lines: Customer actions / [Line of Interaction] / Frontstage employee actions / [Line of Visibility] / Backstage employee actions / [Line of Internal Interaction] / Support processes. Identify failure points (F) và wait points (W). Time each step. Powerful diagnostic tool. HD papers include detailed service blueprint diagram.

Lean Service Operations

Apply Lean principles to services. Service wastes: waiting (customer queue, employee idle), defects (errors requiring rework), overprocessing (gold-plating beyond customer need), excess motion (employees walking, multiple system switching), transportation (moving documents/customers unnecessarily), overproduction (producing reports nobody reads), inventory (work-in-progress paperwork). VSM (Value Stream Mapping) to visualize. Eliminate waste systematically.

Six Sigma in Services

DMAIC: Define (problem, scope), Measure (current performance, baseline), Analyze (root cause), Improve (solution implementation), Control (sustainability mechanisms). Tools: Pareto chart, fishbone diagram, control charts, FMEA, regression analysis. Particularly powerful cho transactional service processes (banking, insurance claims, IT helpdesk) where standardization matters.

Capacity Management Strategies

3 approaches: Chase demand (vary capacity to match demand, e.g., flexible staffing), Level capacity (constant capacity, smooth demand via pricing/promotion/booking), Yield management (price discrimination by segment/time, common in hotels/airlines). Trade-offs: chase = high responsiveness but higher cost variability; level = stable cost but service degradation in peaks; yield = revenue optimization but customer perception risk.

Service Recovery Paradox

Counterintuitive finding: customers experiencing service failure followed by excellent recovery often more loyal than customers who never experienced failure. Implication: invest in robust recovery protocols (apology, fix, compensation, follow-up). 4Rs: Recognize, Respond, Resolve, Recover learning. Empower frontline employees với recovery authority (e.g., Ritz-Carlton's USD 2,000 per employee discretion).

4. Tips làm bài

Tip 1: Service blueprint phải detailed. Không phải sketch generic. Specific steps với time estimates: 'Customer arrives at hotel front desk (0:00). Greeted by receptionist (0:15 sec, frontstage). Receptionist queries PMS system Opera (backstage, 30 sec). Verifies booking (15 sec). Issues key card (45 sec). Total check-in: 1:45 minutes target. Failure points: PMS system slow (>2 min response), card encoder malfunction. Wait point: queue >3 customers exceeds 5-min wait target.' Detail enables targeted improvement analysis.

Tip 2: Real customer voice data. Pull online reviews từ Google Maps, Tripadvisor, Foody, Shopee reviews. Categorize complaints theo SERVQUAL dimensions. Quantify: 'Of 247 reviews analyzed (rating <3 stars), 42% mentioned reliability issues (incorrect orders), 28% responsiveness (long wait), 18% empathy (rude staff), 8% tangibles (cleanliness), 4% assurance (staff knowledge gaps).' Voice-of-customer data grounds analysis in reality.

Tip 3: Process metrics quantitative. Don't say 'long wait times'. Specific: 'Average wait time at peak (12-1pm weekdays): 18 minutes vs target 8 minutes. P90 wait time: 31 minutes (90% of customers wait less than this; 10% experience worse). Service rate per cashier: 45 transactions/hour vs design 60. Capacity utilization: 92% indicating bottleneck (queueing theory predicts exponential wait time growth above 85% utilization).' Metrics surface actionable insights.

Tip 4: Vietnam service context. Vietnamese service expectations evolving rapidly. Younger customers expect digital-first service (mobile app booking, in-app payments, contactless). Tier-1 cities (HCM, Hanoi) expect international-standard service. Tier-2/3 cities relationship-based service still strong. Cultural nuances: respect for elderly customers, family-oriented service approaches, Tet seasonal capacity surges. Bring local context.

Tip 5: Cost-benefit cho recommendations. Each improvement với ROI. VD: 'Initiative: Implement self-service kiosks at 5 highest-volume stores. Investment: USD 80K (5 kiosks x USD 16K). Expected impact: 30% transaction volume shift to self-service, reducing peak-hour cashier need by 2 FTE per store. Annual savings: USD 95K (10 FTE x USD 9,500/year average). Payback: 10 months. Customer benefit: average wait reduced from 18 to 10 minutes at peak. Risk: digital adoption resistance among 50+ customers, mitigated by maintaining 1 staffed line.'

Tip 6: Capacity-demand mismatch analysis. Plot demand pattern (hourly, daily, weekly, seasonal). Compare với capacity. Identify peak vs off-peak gaps. Recommend strategies: peak shifting via pricing (off-peak discounts), capacity flexing (part-time staff), reservation systems, queue management. Service businesses often have severe demand variability; capacity management is differentiator.

Tip 7: Employee dimension critical. Service quality depends on employees. SERVQUAL Empathy và Assurance dimensions employee-driven. HD recommendations address employee side: training programs, empowerment policies, recognition systems, hiring criteria, retention strategies. High employee turnover (>30% annually common in Vietnam services) destroys quality consistency. Connect HR và Operations recommendations.
