Jira Service Management — Série - Partie 4

 

Change Management & Gouvernance des Releases dans Jira Service Management

Dans un support IT mature, on ne se contente plus de résoudre des tickets —
on évite les pannes avant qu’elles n’arrivent.

Cette partie explique comment mettre en place:

  • Gestion des changements (Change Management)

  • Gestion des problèmes (Problem Management)

  • Gouvernance des releases

  • Approbations basées sur le risque

🎯 Objectifs

Passer d’un support réactif → à un support préventif

1️⃣ Change Management — Contrôler les modifications

Un change = toute modification en production :

  • Mise à jour serveur

  • Nouveau logiciel

  • Patch sécurité

  • Modification réseau

Workflow standard


Création → Analyse risque → Approbation → Implémentation → Vérification → Clôture

Types de changements

TypeExempleApprobation
StandardParamètre mineurAutomatique
NormalMise à jour applicativeManager
UrgentIncident productionImmédiate

Approbation basée sur le risque

Plus le risque est élevé → plus il faut d’approbateurs

2️⃣ Problem Management — Supprimer la cause racine

IncidentProblème
VPN en panneMauvaise configuration serveur
PC lentBug logiciel

Workflow RCA


Incidents → Analyse → Cause racine → Known Error → Solution permanente

Résultat : moins d’incidents récurrents

3️⃣ Lien Incident → Problème → Change

Concept central ITIL :

Incident répété → Problème → Change → Correction → Plus d’incident

Sans cela → support reste en mode pompier 🔥

4️⃣ Gouvernance des Releases

Une release doit être planifiée, pas improvisée.

Planification & calendrier


Contrôles :

  • Date de déploiement

  • Impact utilisateurs

  • Plan rollback

  • Validation finale

Politique recommandée

✔ Chaque incident répété crée un problème
✔ Chaque problème crée un change
✔ Chaque change a un rollback
✔ Jamais de déploiement direct en production

CAB recommandé

  • IT Manager

  • Sécurité

  • Ops

  • Responsable applicatif

KPI importants

OOPs Concepts in Java | English | Object Oriented Programming Explained

Image
🔹OOPS (Object Oriented Programming System) in Java Object-Oriented Programming (OOPS) is a programming paradigm that uses classes and objects to design software. It simplifies development and maintenance by applying key concepts: 📌 Class: Class   is a user-defined data type which defines its properties and its functions. Class is the only logical representation of the data. For example, Human beings in an organisation is a class like Employee. The age, name, department, salary etc. of a human being/employee are its properties, and the jobs performed by the employees in an organisation are known as functions.  The class does not occupy any memory space till the time an object is instantiated. A class is a user-defined data type that defines properties and functions. For example: Class: Employee Properties: name, age, salary Functions: work(), attendMeeting() A class does not occupy memory until an object is created. ...

Scopes of Signal in jBPM

Image
💡 Introduction Signals in jBPM 7 are a core part of event-driven workflow design. They allow asynchronous communication between process instances, making it possible to start , interrupt , or coordinate processes without direct linking. However, signals can have different scopes , which define how far the signal travels and who receives it . Let’s explore the four available scopes in detail: 🔹 Process Scope 🔹 Default Scope 🔹 External Scope 🔹 Project Instance Scope 🧩 1️⃣ Process Scope 📘 Definition Process scope signals are local to a single process instance or its child subprocesses . They are not visible outside that instance hierarchy. 📋 Use Case Used for communication inside the same process , like triggering subprocesses or event sub-processes. 🖼️ Process Scope Example Below is an example of a simple process-scoped signal. Only this process (or its subprocess) will catch this signal. ⚙️ 2️⃣ Default Scope 📘 Definition The default scope ...
