流程仍靠 Excel / 人工作業Spreadsheet-heavy operations
同一份資料要填好幾次，版本對不起來，進度只能逐一問人。The same data is entered more than once, versions disagree, and status updates depend on asking people one by one.

找出昂貴、重複、人工且容易出錯的流程，
先算清成本，再決定什麼值得自動化。
Find costly, repetitive, manual workflows.
Quantify first. Automate what pays back.
我協助企業把昂貴、重複、人工且容易出錯的營運流程拆開：量化人力、錯誤、等待與延誤成本，標出必須保留人工裁決的環節，再提出分階段、含價格與預期回收期的改善建議。先做 Operational Workflow Audit，不預設一定要開發系統。
I identify costly, repetitive, manual, and error-prone workflows; quantify labor, errors, waiting time, and delays; preserve the steps that require human judgment; and recommend phased improvements with cost and expected payback. The engagement starts with an Operational Workflow Audit—not a predetermined software build.
常見的起點Where projects usually start
公司一忙，流程上的洞會一起放大。As workload grows, weak processes become harder to hide.
通常不用先談技術。只要下面幾種狀況開始反覆發生，就代表流程、資料或系統責任需要重新整理。
We do not need to start with technology. If these problems keep coming back, the workflow, data, or system ownership needs to be sorted out.
系統分散且難串接Fragmented systems
客戶、訂單、倉儲、財務與報表放在不同地方，任何改動都要人工搬資料。Customer, order, warehouse, finance, and reporting data live in separate places, so every change creates more manual work.
系統常出錯但難追蹤Frequent issues, weak traceability
問題發生時先找人救火，事後沒有紀錄、告警或固定的修復流程，下次再重演一次。Incidents depend on whoever is available. Without records, alerts, and a repeatable recovery process, the same failure returns.
工作內容What I do
把流程做成系統，也把系統顧到能長期運作。I build the workflow into a system and keep that system workable after launch.
CRM / ERP / WMS
- 客戶、訂單、倉儲與內部營運系統建置Customer, order, warehouse, and internal operation systems
- 舊系統重構與資料流程梳理Legacy modernization and data-flow redesign
API & Integration
- 電商、金流、報表、第三方服務串接E-commerce, payment, reporting, and third-party integrations
- 跨系統資料同步與一致性控管Cross-system synchronization and consistency control
DevOps & Reliability
- CI/CD, GitLab, Jenkins
- Grafana, Jaeger, Log4net
- 錯誤追蹤、告警與事件治理Error tracking, alerting, and incident governance
先算再做Quantify before building
人力時間成本計算機Workflow Labor Cost Calculator
先估算一個重複流程每月吃掉多少成本，以及合理自動化後可回收多少。這是初步盤點，不是為了硬塞 AI 或 SaaS。
Estimate the monthly cost of a repetitive workflow and the amount potentially recoverable through practical automation. This is a baseline, not a reason to force AI or SaaS into the process.
目前每月流程成本Current monthly workflow costNT$0
每月可回收成本Potential monthly recoveryNT$0
每年可回收成本Potential annual recoveryNT$0
估算式：人數 × 每人時數 × 人力成本 + 錯誤／延誤成本。正式 Audit 會再納入等待時間、重工、罰款、退款與機會成本，並標示必須保留人工裁決的環節。
Formula: people × hours × loaded hourly cost + error/delay cost. A formal Audit also includes waiting time, rework, penalties, refunds, opportunity cost, and steps that must retain human judgment.
帶著估算結果談 Workflow AuditDiscuss a Workflow AuditABC 實際範例Three practical workflow examples
同一套能力，處理三種不同成熟度的問題。One operating approach applied to problems at three different stages.
A 是長期研究中的金融平台營運風險；B 是已有量化結果的物流改善；C 是可立即執行 Workflow Audit 的小企業流程。只有 B 標示為已驗證成果，避免把研究情境寫成完成案例。
A is an active financial-platform risk scenario; B is a logistics improvement with measured results; C is an audit-ready small-business workflow. Only B is presented as a verified outcome.
A
金融平台：假註冊與流量濫用Financial platform: fake registrations and traffic abuse
研究中的實際情境Active research scenario
大量假註冊或惡意流量可能拖垮註冊服務，讓正常客戶無法完成 onboarding；Sales 承受轉換損失，IT 負責技術處置，管理層承擔品牌與營運風險。
Fake registrations and abusive traffic can overwhelm onboarding, block legitimate customers, create conversion loss for Sales, trigger incident work for IT, and expose management to brand and operating risk.
Audit 重點：Audit focus: 分開 pain owner、technical owner 與 economic buyer，量化中斷對轉換與品牌的影響，再決定防護投資。Separate the pain owner, technical owner, and economic buyer; quantify conversion and brand impact before choosing a protection investment.
B
倉儲物流：重量驗證與物流錯單Warehouse logistics: weight validation and shipping errors
已驗證成果Verified outcome
導入前約 10 次錯單／月，每次平均直接損失約 US$100；投入兩台磅秤約 NT$24,000，加上產品管理與重量驗證系統約 NT$180,000，總投入約 NT$204,000。
Before the change, the operation averaged about 10 shipping errors per month at roughly US$100 direct loss each. Investment included two scales at about NT$24,000 and a product/weight validation system at about NT$180,000.
結果：Result: 錯單由 10 → 2 次／月，約下降 80%；基本直接錯單成本由約 US$1,000 降至 US$200／月，尚未計入重寄、客服、人工處理與物流商罰款。Errors fell from 10 to 2 per month—approximately 80%. Basic direct error cost fell from about US$1,000 to US$200 per month, excluding reshipping, support, labor, and carrier penalties.
C
小企業：薪資／考勤流程Small business: payroll and attendance workflow
可執行的 Audit 情境Audit-ready scenario
考勤、請假、加班與薪資計算常散落在表單、試算表與人工核對中；老闆、HR 與 Accounting 同時付出重複輸入、追資料、月底結算與修正錯誤的時間成本。
Attendance, leave, overtime, and payroll calculations often span forms, spreadsheets, and manual reconciliation, creating repeated entry, follow-up, month-end closing, and correction work for owners, HR, and Accounting.
Audit 重點：Audit focus: 盤點 attendance → payroll calculation、Excel reconciliation、approval、notification；先用現成工具與少量 script 解決，不預設一定要做 SaaS。Map attendance-to-payroll calculation, spreadsheet reconciliation, approvals, and notifications; solve with existing tools and lightweight scripting before assuming a SaaS build.

數字怎麼看Reading the numbers
Issue 變少之後，團隊才有空處理成長。Fewer recurring issues gave the team room to support growth.
Issue Ratio ImprovementIssue Ratio Improvement
透過 CI/CD、監控與標準化流程，Issue ratio 從 2024 年 73% 改善至 2026 年 3%。CI/CD, monitoring, and standardized governance improved issue ratio from 73% in 2024 to 3% in 2026.
Effective Registration GrowthEffective Registration Growth
有效註冊從 2021-10 的 62 成長到 2024-01 峰值 3,873，同時維持平台穩定。Effective registrations grew from 62 in 2021-10 to a peak of 3,873 in 2024-01 while platform operations remained stable.
Deposit & Net Deposit SupportDeposit & Net Deposit Support
支援超過 US$60.5M 總入金與 US$15.36M 累積淨入金相關營運流程。Supported over US$60.5M in total deposits and US$15.36M in cumulative net deposits.
