Which project management maturity level describes a situation where no formal standards or processes are in place?

The situation described is accurately captured by the Ad Hoc maturity level, which indicates that there are no formal standards or processes established for project management. In this level, projects may be executed based on individual initiative or experience, but there is a lack of consistency, structure, or documentation that typically characterizes more advanced maturity levels.

Ad Hoc environments can lead to variability in outcomes and difficulties in replicating successes, as there is little to no focus on measuring performance or implementing best practices. Stakeholders in such environments often rely on informal communication and shared experiences rather than established protocols or guidelines, which can increase the risk of project failure.

In contrast, other maturity levels such as Planned, Managed, and Sustained represent more developed stages where some degree of standardization, planning, and management processes have been established. These involve varying levels of formality in project execution and governance, showcasing a progression towards greater efficiency and effectiveness in project management practices. The absence of formal processes at the Ad Hoc level is what clearly distinguishes it from these more mature stages.
