ガントチャート

ガントチャートは、プロジェクト管理に使用される強力なツールです。ガントチャートは、プロジェクトのスケジュールを視覚的に表し、マネージャーやチームメンバーがプロジェクト全体の開始日と終了日を一目で確認できるようにします。

ガントチャートでは、各タスクはバーで表され、その長さと位置は、タスクの開始日、期間、終了日を反映する。この形式により、あるタスクが完了しないと別のタスクが開始できないような、タスク間の依存関係を理解しやすくなります。さらに、ガントダイアグラムは、マイルストーンを含むことができます。マイルストーンは、プ ロジェクトのタイムラインにおける重要なイベントやゴールであり、明確なシンボル としてマークされます。

ガントチャートを作成するというコンテクストにおいて、PlantUMLはいくつかの利点を提供します。PlantUML は、ダイアグラムの作成にテキストベースのアプローチを提供し、バージョン管理システ ムを使用した変更の追跡を容易にします。このアプローチは、テキストベースのコーディング環境にすでに慣れている チームにとって特に有益です。PlantUML のガントチャート用の構文はわかりやすく、プロジェクトタイムラ インへの迅速な修正や更新を可能にします。さらに、PlantUML の他のツールとの統合や、テキストからダイアグラムを動的に 生成する能力により、プロジェクト管理ドキュメンテーションを自動化し、合理化 したいチームにとって、PlantUML は多目的な選択肢となります。PlantUML をガントチャートに使用することで、ビジュアルなプロジェクトプラン ニングの明瞭さと効率性を、テキストベースのシステムの柔軟性とコントロール性と組み合わせることができます。

タスクの宣言

ガントは自然言語で## 記述され、非常に単純な文（主語-動詞-補語）を使用する。

角括弧を使用して定義されたタスク。

作業量

各タスクの作業量は、requires 動詞を使用して指定され、必要な作業量を日数で示す。

🎉 Copied! 

@startgantt
[Prototype design] requires 15 days
[Test prototype] requires 10 days
-- All example --
[Task 1 (1 day)] requires 1 day
[T2 (5 days)] requires 5 days
[T3 (1 week)] requires 1 week
[T4 (1 week and 4 days)] requires 1 week and 4 days
[T5 (2 weeks)] requires 2 weeks
@endgantt

通常、1週間は7日間と理解される。しかし、（週末など）特定の日が「休業日」に指定されている状況では、1週間を「休業日でない」日で再定義することができる。たとえば、土曜と日曜が休みと指定されている場合、この文脈での1週間は、残りの平日に対応する5日間の仕事量に相当する。

開始

その始まりは、start 動詞を使って定義される：
