Service Request Monitoring Dashboard Using Power Pivot and MxLoader
In today’s digital industrial landscape, data has become an essential part of decision-making. Nearly every major industry relies on data to make operations faster, more accurate, and easier to monitor. One industry that depends heavily on data is the power generation industry.
In a power plant, thousands of pieces of equipment operate continuously, 24 hours a day. From boilers, turbines, conveyors, pumps, and fans to electrical panels and instrumentation, every asset must be constantly monitored. If even a single critical piece of equipment fails, electricity production can be disrupted.
This is why maintenance monitoring is so important. One of the most widely used maintenance management systems is IBM Maximo, an Enterprise Asset Management (EAM) platform used to manage Service Requests (SRs), Work Orders (WOs), equipment history, maintenance schedules, and asset information.
For this project, I developed a simple yet powerful dashboard titled:
“Modeling Dashboard for Monitoring and Analyzing Reliability, Availability, and Maintainability (RAM) from Maximo Data (Service Requests and Work Orders) Using Power Pivot and MxLoader.”
The dashboard combines several easy-to-use tools that significantly improve maintenance data monitoring while allowing online updates.
What Are Reliability, Availability, and Maintainability (RAM)?
Before exploring the dashboard, let’s briefly review the core concepts behind this project.
Reliability
Reliability refers to an equipment’s ability to operate without failure over a specified period.
Examples:
• A conveyor operates continuously for three months without tripping.
• A boiler feed pump experiences no breakdown during operation.
The less frequently equipment fails, the higher its reliability.
Availability
Availability measures how ready equipment is for operation whenever it is needed.
Examples:
• A standby pump is immediately available when the primary pump trips.
• A turbine can be returned to service quickly without extended repair time.
Availability is influenced by several factors:
• Failure frequency
• Repair duration
• Spare parts availability
Maintainability
Maintainability refers to how easily and quickly equipment can be restored after a failure.
Examples:
• A filter can be easily removed and cleaned.
• An electric motor can be replaced quickly thanks to maintenance-friendly design.
The faster repairs can be completed, the better the equipment’s maintainability.
Why Was This Dashboard Developed?
Maintenance departments generate enormous amounts of data. Unfortunately, much of this information simply becomes archived rather than being fully utilized.
Typical maintenance databases contain:
• Thousands of Service Requests
• Numerous Work Orders
• Extensive equipment failure histories
• Operator activity records
• Maintenance logs
When all of this information exists only as long Excel tables or database records, it becomes difficult to extract meaningful insights quickly.
This dashboard was developed to:
• Simplify maintenance monitoring
• Support maintenance analysis
• Identify problematic equipment
• Detect failure trends
• Improve decision-making
It allows engineers and maintenance planners to understand plant conditions from a single screen.
Tools Used
The project utilizes several straightforward yet highly effective tools.

• Bar charts
• Donut charts
• KPI indicators
• Ranking tables
• Interactive filters
The objective is to make maintenance information easy to interpret.
Dashboard Overview
The dashboard features a clean and informative layout, presenting all essential information on a single page so users don’t need to navigate multiple reports.
To protect company confidentiality, certain values and sensitive information shown in the screenshots have been blurred or anonymized.
The dashboard consists of several major sections.
Year and Month Filters
Interactive filters allow users to select:
• Year
• Month
• Unit
• Equipment Group
Examples include:
• Viewing Service Requests for August
• Displaying only Unit 3
• Analyzing only boiler-related equipment
These filters make the dashboard flexible and interactive.
Total Service Requests by Unit
This section displays the number of Service Requests for each generating unit.
Examples:
• Common Area
• Unit 3
• Unit 4
The visualization helps users:
• Identify which unit experiences the most issues
• Compare unit performance
• Prioritize maintenance activities
If one unit records significantly more Service Requests than others, engineers can investigate further.
Total Service Requests by Equipment Group
The dashboard categorizes Service Requests by equipment groups such as:
• Boiler
• CNI
• Electrical
• Turbine
This helps maintenance teams determine which plant systems experience the highest number of failures.
For example:
• If the Boiler group records the highest number of Service Requests, additional inspections may be necessary.
• If Turbine-related Service Requests suddenly increase, preventive actions may be required.
Simple analyses like these provide valuable maintenance insights.
Service Requests by Status
The dashboard tracks work status, including:
• Closed
• In Progress
• SRJT (or other custom statuses)
This enables users to monitor:
• Completed work
• Ongoing work
• Maintenance backlog
A high number of “In Progress” jobs may indicate:
• Insufficient manpower
• Spare parts shortages
• Inefficient maintenance prioritization
Service Requests by Type
The dashboard also classifies maintenance activities according to work type.
Examples include:
• ORD
• PDM
This helps engineers understand which maintenance activities dominate plant operations.
Annual Service Request Trends
A yearly trend chart allows users to evaluate long-term maintenance performance.
Questions that can be answered include:
• Are equipment failures increasing?
• Is reliability improving?
• Is the maintenance strategy producing positive results?
Trend analysis plays an important role in continuous improvement.
Top 10 Equipment with the Highest Number of Service Requests
One of the most valuable sections of the dashboard is the equipment ranking.
It displays:
