Diagramme de Gantt

Le diagramme de Gantt est un outil puissant utilisé pour la gestion de projets. Il représente visuellement le calendrier d'un projet, permettant aux responsables et aux membres de l'équipe de voir d'un seul coup d'œil les dates de début et de fin de l'ensemble du projet. Le diagramme affiche les tâches ou les activités le long d'un axe temporel horizontal, montrant la durée de chaque tâche, leur séquence et la façon dont elles se chevauchent ou se déroulent simultanément.

Dans un diagramme de Gantt, chaque tâche est représentée par une barre, dont la longueur et la position reflètent la date de début, la durée et la date de fin de la tâche. Ce format permet de comprendre facilement les dépendances entre les tâches, lorsqu'une tâche doit être achevée avant qu'une autre ne puisse commencer. En outre, les diagrammes de Gantt peuvent inclure des jalons, qui sont des événements ou des objectifs importants dans la chronologie du projet, marqués par un symbole distinct.

Dans le contexte de la création de diagrammes de Gantt, PlantUML offre plusieurs avantages. Il offre une approche textuelle de la création de diagrammes, ce qui facilite le suivi des modifications à l'aide de systèmes de contrôle des versions. Cette approche est particulièrement bénéfique pour les équipes qui sont déjà habituées à des environnements de codage basés sur le texte. La syntaxe de PlantUML pour les diagrammes de Gantt est simple, ce qui permet des modifications et des mises à jour rapides de la chronologie du projet. De plus, l'intégration de PlantUML avec d'autres outils et sa capacité à générer des diagrammes dynamiquement à partir de texte en font un choix polyvalent pour les équipes qui cherchent à automatiser et à rationaliser leur documentation de gestion de projet. L'utilisation de PlantUML pour les diagrammes de Gantt combine donc la clarté et l'efficacité de la planification visuelle de projet avec la flexibilité et le contrôle d'un système basé sur le texte.

Déclaration des tâches

Le Gantt est décrit en langage naturel, à l'aide de phrases très simples (sujet-verbe-complément).

Tâches définies à l'aide de crochets.

Charge de travail

La charge de travail pour chaque tâche est spécifiée à l'aide du verbe requires, indiquant la quantité de travail nécessaire en termes de jours.

🎉 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

Une semaine est généralement comprise comme une période de sept jours. Toutefois, dans les contextes où certains jours sont désignés comme "fermés" (comme les week-ends), une semaine peut être redéfinie en termes de jours "non fermés". Par exemple, si le samedi et le dimanche sont désignés comme fermés, une semaine dans ce contexte équivaudra à une charge de travail de cinq jours, correspondant aux jours de semaine restants.
