This article marks the conclusion of my 30-day iThome Iron Man series on e-signature technology and project management. Over the past month, we’ve embarked on a comprehensive journey to create a clear strategic roadmap from the fundamentals of e-signatures to real-world project implementation.

Let’s recap the four key parts of this journey.

Part 1 : Foundational Knowledge

We began by exploring the essential concepts. This included clarifying the differences between e-signatures and digital signatures, understanding Taiwan’s Electronic Signature Act, and learning the fundamentals of Public Key Infrastructure (PKI).

Part 2 : Practical Implementation & Technology

In the second part, we explored the project manager’s role in technical implementation. This included how to read API documentation and walk through the user signing journey step by step. We also took a closer look at key components of digital evidence, such as audit trails, PDF structures, timestamps, and the signature verification process.

Part 3 : Strategic Insights for Project Managers

In this part, we walked through the entire project lifecycle, from gathering requirements to final delivery, ensuring that users could successfully adopt the system. We also explored key strategies for communication, planning and handing challenges, while reflecting on the core value of being a project manager.

Part 4 : Advanced Topics

In the final part, we explored the diverse methods of Identity Verification (IDV) and emphasized the importance of Long-Term Validation (LTV) in ensuring the legal admissibility of digital documents. Additionally, we explored how digital evidence can be used effectively in legal proceedings, and took a brief look at the EU’s eIDAS regulation.

Final Thoughts

The core of digital transformation has never been about the tools themselves, but about using them to optimize processes, reducing risks, and enhance the human experience.

Thank you to everyone who took the time to read my series. Whether you’re a project manager or not, I truly hope you found something meaningful here, If even one sentence helped you, that would make me feel satisfied.

I don’t know when we’ll meet again, but maybe by then, I’ll have taken another leap forward in my career. The first time I joined this challenge, I was preparing to transition into frontend engineering. Now, I’ve stepped into a new role as a project manager. Life keeps moving, and it’s hard to predict where I’ll be a year from now .

Until next time, I hope I’ll have something new to share with you. See you then!

終於！來到這系列的最後一天啦！！
這 30 天下來真的是無限感慨，就像昨天說的，這次的鐵人賽不僅僅是一場挑戰，也是一趟我自己對知識重構與自我對話的旅程。

從電子簽章的基礎定義和法規，到 PM 的專案實戰。希望透過我這 30 天的實務經驗與學習筆記，能讓大家清楚的看懂這幅由電子簽章系統的 PM 所描繪的「簽章戰略」。

看看這四週的回顧

第一部份：打地基

首先我們從釐清電子簽名、電子簽章與數位簽章的差異開始，接著解讀了 2024 年修法後的《電子簽章法》，並用簡單的比喻，學會了什麼是 PKI。

第二部份：來點技術

我們用 PM 的視角學會了如何解讀 API 文件、體驗了簽署者的流程，並深入探討數位證據的幾個要素，包含：稽核軌跡、時間戳、PDF 載體與驗證流程。

第三部份：PM 的心法

在這部份，我們完整的走過了一個專案從需求訪談到最終交付且讓使用者採納的生命週期，分享了身為 PM 在規劃、溝通與變動中的實戰攻略，學習專案管理者的核心價值。

第四部份：進階學習

在最後這部份，我們探討了 IDV 的多樣性、LTV 的長遠佈局、實務的法律攻防，以及跨國法規 eIDAS。

最後的最後

如果你也是一位 PM 或是企業主管，希望這 30 天的文章能讓大家知道，數位轉型的核心，從來就不是導入一套厲害的工具來取代紙張就叫數位轉型，而是要去思考如何優化流程、降低風險、解決問題，並且提升人的體驗。

最後感謝所有點開來看的你們，無論你是不是 PM，都希望你能夠從文章中獲得東西；如果你是 PM，那就更加希望我的文章能幫到你，哪怕只是其中一段文字，我也都會感到無比滿足。

下次見面時不知道我會不會又做出職涯的躍進了？想想初次參賽時是準備轉職前端工程師，這次是已經從工程師轉為 PM，人生就是一直前進，很難預測明年的自己會在哪。

希望下次見面時我又有不同的東西可以跟各位分享，那就期待那時候再見啦~
