 A run chart is a graph that displays observed data in a time sequence1. It is often used to visualize trends or patterns over time1. In the context of healthcare quality, a run chart would be the most suitable tool to display nosocomial infection rates over time1. This is because it allows for the tracking of changes in the data over time, which can help in identifying any trends or shifts in the process1. This can be particularly useful in monitoring infection rates, as it can help in identifying periods of increase or decrease, which can then be investigated further1.

A process map is a tool that shows the sequence of steps or activities involved in a process, and identifies the inputs, outputs, and decision points. It can help to identify waste, variation, and inefficiencies in a process, and to design or redesign a process for improvement. However, it does not show the time required or allocated for each step or activity, nor the dependencies or interrelationships among them. Therefore, it is not the best tool to use for establishing a timeline for implementation.

A Gantt chart is a tool that shows the tasks or phases of a project, the duration and order of each task or phase, the milestones or deliverables, and the progress or status of each task or phase. It can help to plan and schedule a project, to monitor and communicate its progress, to identify critical tasks or phases, and to allocate resources and responsibilities. Therefore, it is the best tool to use for establishing a timeline for implementation.

An Ishikawa diagram (also known as a fishbone diagram or a cause-and-effect diagram) is a tool that shows the possible causes of a problem or an effect, and organizes them into categories or branches. It can help to identify the root causes of a problem, to brainstorm potential solutions, and to prioritize areas for improvement. However, it does not show the time or sequence of the causes or solutions, nor the tasks or phases of a project. Therefore, it is not the best tool to use for establishing a timeline for implementation.

A bar graph (also known as a histogram or a column chart) is a tool that shows the frequency or distribution of data in different categories or groups, using vertical or horizontal bars. It can help to compare data across categories or groups, to identify patterns or trends, and to display numerical information visually. However, it does not show the time or sequence of the data, nor the tasks or phases of a project. Therefore, it is not the best tool to use for establishing a timeline for implementation. References:

 A control chart is a statistical tool used in quality control to monitor and control processes. It helps to determine how much variability in a process is due to random variation and how much is due to unique events.

Random variation, also known as common cause variation, is inherent in any process and is predictable1. It represents the natural fluctuation in a process over time due to many minor factors1.

On the other hand, unique events, also known as special cause variation, are unexpected and arise due to unusual circumstances23. They are not an inherent part of a process and are not predictable3.

A control chart helps distinguish between these two types of variation. If a data point falls within the control limits on the chart, it is considered to be due to random variation. If a data point falls outside the control limits, it indicates the presence of special cause variation1.
