Activity Subtask

Sous-tâche d'activité au sein d'un projet

Catégorie : Planification et ordonnancement de projet

Définition : Une sous-tâche d'activité est une unité de travail plus petite et plus gérable qui contribue à l'achèvement d'une activité de projet plus large.

Objectif :

  • Décomposer des activités complexes : Les sous-tâches aident à diviser les activités vastes et complexes en éléments plus petits et plus faciles à digérer.
  • Améliorer l'organisation et la clarté : En décomposant les activités en sous-tâches, les équipes de projet peuvent mieux comprendre la portée et la séquence du travail.
  • Améliorer la gestion des tâches : Les sous-tâches permettent un suivi et un contrôle plus efficaces des progrès.
  • Faciliter la délégation : Les sous-tâches peuvent être attribuées à des membres spécifiques de l'équipe, favorisant la responsabilisation et la collaboration.
  • Promouvoir la flexibilité et l'adaptabilité : Si une sous-tâche nécessite des ajustements, elle peut être modifiée sans affecter le plan global du projet de manière significative.

Considérations clés :

  • Identifier les dépendances : Définir l'ordre dans lequel les sous-tâches doivent être réalisées.
  • Estimer la durée et les ressources : Attribuer des délais et des besoins en ressources réalistes à chaque sous-tâche.
  • Suivre les progrès : Surveiller régulièrement l'état de chaque sous-tâche et ajuster les plans si nécessaire.
  • Communiquer clairement : S'assurer que toutes les parties prenantes comprennent l'objectif et la portée de chaque sous-tâche.

Exemples :

  • Activité : Développer un nouveau produit
    • Sous-tâches : Réaliser des études de marché, concevoir le produit, créer un prototype du produit, tester le produit, finaliser la conception du produit.
  • Activité : Planifier une conférence
    • Sous-tâches : Trouver un lieu, réserver des conférenciers, créer des supports marketing, inscrire les participants, gérer la logistique.

Avantages :

  • Amélioration de l'efficacité et de la productivité du projet
  • Amélioration de la communication et de la collaboration
  • Responsabilisation et appropriation accrues
  • Amélioration de la gestion des risques et de l'atténuation
  • Suivi et reporting de projet plus précis

Conseils :

  • Utiliser un outil de gestion des tâches : Tirer parti d'outils comme Trello, Asana ou Jira pour gérer efficacement les sous-tâches.
  • Gardez les sous-tâches ciblées et spécifiques : Chaque sous-tâche doit avoir un objectif clair et une portée bien définie.
  • Revoir et ajuster régulièrement les sous-tâches : S'adapter aux exigences changeantes du projet et s'assurer que les sous-tâches restent pertinentes.

En mettant en œuvre efficacement les sous-tâches d'activité, les équipes de projet peuvent améliorer la planification, l'exécution et le succès global du projet.
