the work in the past. In most cases, documentation is the most successful way to monitor and control the specific phases of a project. With the correct documentation, a project's success can be tracked and observed as the project goes on. If performed correctly documentation can be the backbone of a project's success Monitoring and controlling Monitoring and controlling consist of those processes performed to observe project execution so that potential problems can be identified in a timely manner and corrective action can be taken, when necessary, to control the execution of the project. The key benefit is that project performance is observed and measured regularly to identify variances from the project management plan. Monitoring and controlling include: Measuring the ongoing project activities ('where we are'); Monitoring the project variables (cost, effort, scope, etc.) against the project management plan and the project performance baseline (where we should be); Identifying corrective actions to address issues and risks properly (How can we get on track again); Influencing the factors that could circumvent integrated change control so only approved changes are implemented. Two main mechanisms support monitoring and controlling in projects. On the one hand, contracts offer a set of rules and incentives often supported by potential penalties and sanctions. On the other hand, scholars in business and management have paid attention to the role of integrators (also called project barons) to achieve a project's objectives. In turn, recent research in project management has questioned the type of interplay between contracts and integrators. Some have argued that these two monitoring mechanisms operate as substitutes as one type of organization would decrease the advantages of using the other one. In multi-phase projects, the monitoring and control process also provides feedback between project phases, to implement corrective or preventive actions to bring the project into compliance with the project management plan. Project maintenance is an ongoing process, and it includes: Continuing support of end-users Correction of errors Updates to the product over time In this stage, auditors should pay attention to how effectively and quickly user problems are resolved. Over the course of any construction project, the work scope may change. Change is a normal and expected part of the construction process. Changes can be the result of necessary design modifications, differing site conditions, material availability, contractor-requested changes, value engineering, and impacts from third parties, to name a few. Beyond executing the change in the
