Meet Adam an aspiring entrepreneur, he is interested in hosting an online store for home decor products like vases, curtains, artwork and home furnishings.

認識一下有抱負的創業者 Adam，他對經營一個販售花瓶、窗簾、藝術品和居家擺飾等居家裝飾產品的線上商店很感興趣。

He requires a software application that would allow the customers to browse the available products at their fingertips and buy them online.

他需要一個軟體應用程式，讓顧客可以隨時隨地瀏覽現有產品並在線上購買。

Adam, eager to jump into his new business, wanted to understand how this software development process works.

Adam 迫不及待地想開始他的新事業，他想了解這個軟體開發流程是如何運作的。

To start with his business idea, Adam meets his cousin Mark, who is a software developer and a good one at it.

為了啟動他的創業點子，Adam 遇見了他的表哥 Mark，Mark 是一位優秀的軟體開發人員。

He pitches his idea and asks his cousin to help him design an online business application.

他提出了自己的想法，並請表哥幫他設計一個線上商業應用程式。

Mark explains to Adam the way of designing the best online shopping application we need to understand the working of the software development lifecycle, also known as the sdlc.

Mark 向 Adam 解釋，為了設計出最好的線上購物應用程式，我們需要了解軟體開發生命週期（也稱為 SDLC）的運作方式。

It involves distinctive phases to initiate the software production based on the client requirements.

這包含幾個不同的階段，以便根據客戶需求啟動軟體生產。

Further, Mark briefs Adam about the six crucial phases of SDLC in designing any software Planning requirements phase, Requirement Analysis phase, Designing phase, Implementation phase, Testing phase Deployment and maintenance phase the development team will commence production post agreeing on the terms and conditions discussed between the client and the development team regarding all the proceedings and requirements.

接著，Mark 向 Adam 簡述了 SDLC 的六個關鍵階段，用於設計任何軟體：規劃需求階段、需求分析階段、設計階段、實施階段、測試階段，以及部署與維護階段。開發團隊會在客戶與開發團隊就所有事項和需求達成共識後，開始進行生產。

Initiating the production with the Planning requirements phase where the client and the development team will discuss the basic requirements for the software like the purpose of the application, the details about the end user of the product, key elements like format and attributes of the application for designing, and

透過規劃需求階段來啟動生產，在這個階段，客戶與開發團隊將討論軟體的基本需求，例如應用程式的目的、產品終端使用者的詳細資訊、應用程式的格式和屬性等關鍵要素，以便進行設計，

Design of the Software the development moves on to the second stage, the requirement analysis phase, which includes the detailed information about each element to design the software as discussed, validating the installation of elements in the application according to the client's requirements, calibrating the security protocols and performing risk analysis for the software application.

軟體的設計接著進入第二階段，也就是需求分析階段，這包含設計軟體時討論的每個元素的詳細資訊，根據客戶需求驗證應用程式中元素的安裝，校準安全協定並對軟體應用程式進行風險分析。

All the discussed details are then to be filed in the Software Requirements Specification Document, also known as the SRS document.

所有討論過的細節都將歸檔於軟體需求規格文件，也稱為 SRS 文件。

After completing the second phase, third stage of software development, the design phase, the software designers will devise the system design following the SRS document.

完成軟體開發的第二階段、第三階段（設計階段）後，軟體設計師將依照 SRS 文件設計系統。

The system design defines the overall architecture of the software and checks its feasibility with the client's requirements.

系統設計定義了軟體的整體架構，並根據客戶需求檢查其可行性。

All the details of the design phase are added to the design document specification, also known as the DDS document, and

設計階段的所有細節都會加入設計文件規格，也稱為 DDS 文件，並

shared with the analysts and stakeholders for review.

與分析師和利害關係人分享以供審閱。

Next, the development moves on to the fourth stage, the coding or implementation phase.

接著，開發進入第四階段，也就是編碼或實施階段。

In the coding phase, the developers start writing the code using the languages they choose for the software development.

在編碼階段，開發人員會開始使用他們選擇的程式語言來編寫軟體開發的程式碼。

The coding stage is also one of the most important phases as it encapsulates the implementation of the software product.

編碼階段也是最重要的階段之一，因為它包含了軟體產品的實施。

The developers use predefined guidelines and development tools like compilers and debuggers to implement the code.

開發人員會使用預定義的指南和開發工具，如編譯器和偵錯器來實施程式碼。

The next phase of the production is where we begin with the fifth stage of software development, the testing phase.

接下來的軟體生產階段，我們要進入軟體開發的第五個階段：測試階段。

The developed software is now deployed in multiple test environments to check the functioning of all the attributes in the software architecture.

開發好的軟體會部署到多個測試環境，檢查軟體架構中所有屬性的功能。

After the test cases are completed, the quality assurance and the testing team may find errors or bugs in the software which will be forwarded to the developer team for debugging.

測試案例完成後，品保和測試團隊可能會發現軟體中的錯誤或 bug，這些會轉交給開發團隊進行除錯。

This testing and debugging process continues until the software is stable and works per the required specifications.

這個測試和除錯的過程會一直持續，直到軟體穩定並符合所需規格。

As for the last stage in the SDLC lifecycle, the deployment and maintenance phase is initiated.

至於 SDLC 生命週期的最後一個階段，就是部署與維護階段。

With the testing phase completed, the software application is ready for deployment and consumer use.

測試階段完成後，軟體應用程式就準備好部署供消費者使用了。

In this phase, the development team will set up links for the application and and make it accessible to the users.

在這個階段，開發團隊會設定應用程式的連結，並讓使用者能夠存取。

After the deployment is completed and users begin using the application, they may encounter an error or a bug in the application which is to be solved from time to time.

部署完成且使用者開始使用應用程式後，他們可能會遇到應用程式中的錯誤或 bug，這些需要不時解決。

Maintenance also includes releasing application updates and enhancements for the software for better performance and user experience.

維護還包括發佈應用程式更新和增強功能，以提升軟體的效能和使用者體驗。

Adam at this point was surprised by all the effort and steps taken by the development team to design a software application and the key phases involved in sdlc.

這時候 Adam 對開發團隊為了設計軟體應用程式所付出的努力和步驟，以及 SDLC 中涉及的關鍵階段感到驚訝。

And on that note, here's a question for you all.

接著，這裡有個問題想問大家。

What does the design document specification document include?

設計規格文件裡包含哪些內容呢？

Software code details on defects and bugs Software architecture details Software requirements Give it a thought and leave your answers in the comments section below.

軟體程式碼的缺陷與錯誤細節、軟體架構細節、軟體需求。請大家想一想，並在下方的留言區留下你的答案。

Three lucky winners will receive Amazon Gift Vouchers With Mark's explanation of the SDLC lifecycle, Adam understood how software is developed.

三位幸運得獎者將會獲得亞馬遜禮券。透過 Mark 對 SDLC 生命週期的說明，Adam 瞭解了軟體是如何開發的。

Now he can actively give feedback to the development team and design the best software application for his online store and maybe expand to other businesses as well.

現在他可以積極地向開發團隊提供意見，並為他的線上商店設計出最佳的軟體應用程式，甚至可能擴展到其他業務。
