WHAT IS BENCHMARKING…?o Continuous, Systematic process of
measuring one’s output and/or work process against the toughest competitors.
o Organization evaluate various aspect of the process in relation to best practicing companies.
o Dimensions measured are Quality, Time & Cost.

TYPES
Financial benchmarking performing a financial
analysis comparing the resultsPerformance benchmarking allows the initiator firm to
assess their competitive position
Product benchmarking process of designing new
products or upgrades to current ones

TYPES
Strategic benchmarking involves observing how others
competeOperational benchmarking involves staffing and
productivity to office flow and analysis of procedures performed
Best-in-class benchmarking involves studying the leading
competitor

GANTT CHART A GANTT chart is a type of bar chart that illustrates
a project schedule. It was introduced by Henry Gantt around 1910 –
1915. Re-allocate resources and Re-schedule if
necessary. Work breakdown structure.

GANTT CHARTGantt Charts(G) are useful tools for analyzing
and planning complex projects. It includes:- planning Scheduling Allocation of resources Help you to work out the critical path for a
project where you must complete it by a particular date.

GANTT CHART Characteristics:
The bar in each row identifies the corresponding task The horizontal position of the bar identifies start and
end times of the task Bar length represents the duration of the task Task durations can be compared easily Good for allocating resources and re-scheduling Precedence relationships can be represented using
arrows Critical activities are usually highlighted Slack times are represented using bars with doted lines The bar of each activity begins at the activity earliest start time (ES) The bar of each activity ends at the activity latest finish time (LF).

DisadvantagesDependencies are more difficult to
visualiseMinor changes in data can cause major
changes in the chart

CONSTRUCTING GANTT CHART
The steps to construct a GANTT chart are:1. Schedule the critical tasks in the
correct position.2. Place the time windows in which the
non-critical tasks can be scheduled.3. Schedule the non-critical tasks
according to their earliest starting times.
4. Indicate precedence relationships between tasks.

CONSTRUCTING GANTT CHART
Example of an early GANTT chart construction:
Step 1. Schedule critical tasks. Step 2. Place time windows for non-critical tasks.

STAFFING & RE-SCHEDULING
Once the project schedule, (e.g. GANTT chart), has been constructed, take into account available staff hours slack times and the project schedule
Resource Smoothing is a technique used to re-allocate resources and re-schedule activities.
In resource smoothing, non-critical tasks are re-scheduled within their time window.
Staff Utilization:(duration of activity x staff required for each activity, all added together) / (maximum staff required x duration of project)

STAFFING & RE-SCHEDULING
17
The original schedule (constructed above) for this project is as shown below.
1. Staff utilisation = (3x2+4x4+5x1+7x3+2x1+4x2+3x5)/(14x6) = 0.857 = 85.5%

2. Work out the Staff Profile

STAFFING & RE-SCHEDULING Now, assume that there are 6 people available for
working in this project but one of them returns from holidays at time=2.
So re-scheduling is needed because activities A and B cannot be carried out in parallel until time=2.

CONCLUSION
As is clearly apparent, benchmarking can add value to the organization's workflow and structure, by identifying areas for improvement and rectification.
Gantt chart tools make project manager’s life easy. Therefore, Gantt chart tools are important for successful project execution.
