Project impact assessment

Optimize your decisions with Carto-SI

In an environment where information systems (IS) play a key role in business performance, every project, every evolution or transformation has significant potential repercussions.

Carrying out an impact study then becomes an essential step in measuring the consequences of the planned changes on the IS architecture. Thanks to Carto-SI, assessing the impact of a project is not only made easier, but also optimized to guarantee informed and effective decision-making.

What is an impact study in an IS context?

An impact study, also known as an impact analysis, involves assessing the consequences of a project or change on the various components of an information system: applications, business processes, infrastructures and data flows. It aims to answer several strategic questions:

• Which IS elements will be directly or indirectly affected?
• What potential risks (interruptions, security breaches, budget overruns) need to be anticipated?
• How can we minimize negative effects and maximize opportunities?

Carrying out a rigorous impact study is an essential step in project management, whether for migrations, infrastructure modernization or software upgrades.

When and why carry out an impact study?

An impact study is required in many cases, particularly when :

• A project involves critical IS components (strategic applications, sensitive databases, network infrastructures).
• Complex dependencies make it difficult to assess the effects of change.
• A company wants to anticipate the risks associated with a digital transformation (cloud migration, deployment of new software solutions, etc.).

The main aim of an impact study is to minimize the unexpected and maximize the expected benefits. With a clear view of the possible consequences, companies can avoid costly mistakes and maintain business continuity.
