About Manuella

When IT delivery becomes a risk for the organization, I step in to secure execution and structure a sustainable operating model.

Positioning

Instability in production releases, poorly managed dependencies, lack of visibility:
I support IT Directors and Program Managers in **transforming their delivery model**, by aligning organization, governance, and execution.

I intervene in **complex multi-team and multi-application IT environments**, with one objective: **restore the performance and predictability of delivery**.

Approach

My approach combines Delivery Management, Release Management, and DevOps transformation, with a structured analysis methodology (Lean Six Sigma – Green Belt).

Interventions

  • Diagnosis of theactual delivery flow(Value Stream Mapping)
  • Identification ofstructural bottlenecks and root causes
  • Structuring ofdelivery and release governance
  • Definition of aTarget Operating Model(delivery / DevOps / multi-team coordination)
  • Implementation of performance-based steering (**DORA, flow metrics**)

Objectives

  • Secure production releases
  • Restore delivery predictability
  • Reduce critical dependencies
  • Align IT capacity with business priorities

Intervention Formats

I intervene in:

*targeted diagnosis (a few days to a few weeks)

*part-time transverse support (1 to 3 days/week)for critical IT transformation phases

Mission Examples

  • Delivery model transformation
  • Multi-team governance structuring
  • Securing critical programs

    Structuring of a multi-phase delivery model – SAFe IT Program (approx. 180 people)

    Program structured in several parallel phases within a complex IT system, generating risks of collision between streams: unmanaged dependencies, prioritization conflicts, potential instability of production releases.

    **Challenge**: maintain execution capacity while parallelizing phases.

    Intervention:

    • Structured diagnosis of theactual delivery flow (DMAIC)
    • Mapping ofinter-phase interactions (Value Stream Mapping)
    • Identification ofroot causes of conflicts and critical dependencies
    • Analysis ofsystemic risk related to the coexistence of phases
    • Definition of a **target multi-phase delivery model**: arbitration mechanisms, release governance, synchronization rules, and dependency management

    Impacts:

    • Control of the risk associated with the coexistence of phases
    • Stabilization of production release mechanisms
    • Structuring of a multi-stream delivery model
    • Strengthening of the program's execution capacity
