瀑布方法定義
Waterfall methodology (or waterfall model) in project management is a sequential and linear approach used to manage projects. It follows a structured process where each phase of the project is completed before moving on to the next. The methodology is called “waterfall” because progress flows steadily downward, similar to a waterfall.
瀑布模型可用於各個領域,包括軟件開發、工程和施工。 它通常用於有嚴格期限、有限預算和固定範圍的項目。
瀑布方法論的 6 個階段
The Waterfall Methodology follows a sequential approach to project management, consisting of distinct phases. Let’s explore these phases in a simplified manner:

1/ 需求收集:
In this phase, project requirements are identified and documented. Project stakeholders participate to ensure that their requirements and expectations are well understood. The phase’s goal is to establish a solid foundation for the project by defining what needs to be achieved.
例如,您有一個新電子商務網站的軟件開發項目。 在此階段,您的項目團隊將:
- 與各種利益相關者(例如企業主、營銷專家和潛在的最終用戶)互動,收集他們的意見和要求。
- 進行訪談、會議和研討會,以了解網站的目標、功能和期望。
2/ 設計:
Once the requirements are gathered, the design phase begins. Here, the project team creates a project’s detailed plan or blueprint. It includes defining the structure, components, and user experiences.
The Design phase aims to ensure that everyone involved, including developers, designers, and all stakeholders, has a clear vision of the project’s structure and appearance.
3/實施:
在實施階段,進行實際的開發工作。 項目團隊開始根據設計規範構建項目可交付成果。
把它想像成建造一座房子。 實施階段是建築商開始對地基、牆壁、屋頂、管道和電氣系統進行施工的階段。 他們遵循建築計劃並將其轉化為有形的結構。
同樣,在此階段,開發人員遵循先前創建的設計計劃並編寫使項目正常運行所需的代碼。 它們將項目的不同部分(例如特性、功能和界面)組合在一起,並以能夠順利運行的方式將它們連接起來。
4/ 測試:
實施階段後,將進行嚴格的測試,以確保項目的質量和功能。 執行各種類型的測試,例如單元測試、集成測試和系統測試,以識別任何缺陷或問題。
測試階段旨在驗證項目是否滿足指定的要求並按預期執行。
5/部署:
部署是項目準備好發布和使用的階段。 它發生在測試階段完成之後。
在部署階段,項目可交付成果(例如軟件或網站)在現實世界中發布和實施。 它們要么安裝在生產環境中,其中一切都設置為實際使用,要么交付給請求該項目的客戶。
- For example, if it’s a website, the project team would set up the web servers, databases, and any other required infrastructure. They would ensure that everything is properly configured and working smoothly.
6/ 維護:
在維護階段,項目團隊提供持續的支持,以解決可能出現的任何問題。 維護階段的主要目標是確保項目保持良好運行並滿足用戶的期望。
- If any bugs or issues are discovered in the project, the team works on fixing them.
- The team also looks into making necessary changes or improvements to the project based on user feedback or new requirements. It’s similar to when you suggest adding a new feature to your favorite app, and the developers listen and make it happen.
只要項目正在進行,項目團隊就會繼續提供支持、解決任何問題並進行必要的更新或更改。 這有助於保持項目的可靠性、安全性和最新性。

瀑布方法的優點和缺點
Benefits Of Waterfall Methodology
- 清晰且結構化的方法: 該方法提供了一種清晰且有組織的方式來管理項目。 它遵循循序漸進的過程,使團隊更容易規劃和執行他們的工作。
- 詳細文檔: 該模型強調每個階段文檔的重要性。 這意味著項目要求、設計計劃和實施細節都有詳細記錄。 該文檔可供將來參考,並有助於保持組織內知識的完整性。
- 早期確定需求: 該方法側重於儘早識別和定義項目需求。 通過這樣做,您可以最大限度地減少潛在的誤解或範圍變化。 它從一開始就為項目提供了堅實的基礎。
- 明確的里程碑和可交付成果: 這種方法允許在項目的每個階段設置明確的里程碑和可交付成果。 這有助於項目經理跟踪進度並根據預定義的目標衡量成功情況。 當團隊完成每個里程碑時,它會帶來成就感。

Drawbacks Of Waterfall Methodology
- 有限的靈活性: The methodology has the downside of being inflexible. Once a phase is completed, it becomes challenging to make changes. This limitation can cause difficulties in adapting to evolving requirements or incorporating feedback later in the project. It may restrict the project’s ability to be flexible and responsive to changing needs.
- 缺乏利益相關者的參與: 在此模型中,利益相關者的參與可能有限,並且僅在項目的後期階段提供反饋。 如果最終結果未達到利益相關者的期望,這種延遲參與可能會導致意外或失望。
- 代價高昂的變更風險更高: Due to the sequential nature of the methodology, making changes or addressing issues discovered in later stages can be time-consuming and expensive. Modifying the project requires going back to previous phases, which can disrupt the project’s timeline and budget. These changes may lead to additional costs and delays.
- 對不確定性的適應性有限: 該模型假設項目需求在一開始就可以被充分理解和定義。 然而,在復雜的項目或不確定的環境中,預先完全理解可能具有挑戰性。 當遇到意外情況或不斷變化的情況時,這種限制可能會導致難以實現預期結果。
Different methods may be more appropriate for the specific requirements of the project and organizational context. So, let’s go to the next section to know when you should apply the waterfall model!
When and Where Should Apply The Waterfall Methodology?
這種方法通常應用於具有明確定義和穩定需求的項目,其中項目有明確的目標和範圍。 這種模式在建築、工程、製造和軟件開發等行業中很常見。

以下是可以有效應用瀑布方法的一些場景:
- 連續且可預測的項目: 它非常適合具有明確任務順序和可預測流程的項目,例如建造建築物。
- 目標明確的小型項目: 它對於具有明確目標的小型項目非常有效,例如開發簡單的移動應用程序。
- 穩定的要求和有限的變化: 當項目需求穩定並且不太可能發生重大變化時,瀑布方法論是合適的。
- 合規性和文件要求: 它對於需要完整記錄並遵守法規的項目(例如醫療保健或航空航天行業)非常有益。
- 具有明確用戶需求的項目: 它適用於從一開始就清楚了解用戶需求的情況,例如根據特定客戶規範構建網站。
It’s important to remember that Waterfall Methodology may not be suitable for projects requiring adaptability, frequent stakeholder involvement, or responsiveness to changing requirements. In such cases, Agile methodologies are often preferred.
關鍵要點
瀑布方法非常適合具有連續和可預測任務的項目、具有明確目標的小型項目或定義明確的用戶項目。 然而,它可能不適合需要適應性和利益相關者頻繁參與的項目。
