Why KPI dashboards in SCADA systems? - Purpose & Use Cases

The Big Idea

What if you could see your entire factory's health in one glance, anytime you want?

The Scenario

Imagine you are managing a factory floor with many machines and processes. You try to track key performance indicators (KPIs) like uptime, production rate, and energy use by checking multiple spreadsheets and handwritten logs every day.

The Problem

This manual tracking is slow and confusing. You waste time gathering data from different sources, and mistakes happen easily when copying numbers. By the time you finish, the data is already outdated, making it hard to react quickly to problems.

The Solution

KPI dashboards automatically collect and display important metrics in one clear view. They update in real time, so you always see the latest performance. This helps you spot issues fast and make better decisions without digging through piles of data.

Before vs After

✗ Before

Check spreadsheets daily; write notes by hand; calculate averages manually

✓ After

Use dashboard software to show live KPIs with charts and alerts

What It Enables

KPI dashboards let you monitor complex operations instantly and act quickly to improve results.

Real Life Example

A plant manager uses a KPI dashboard to see machine downtime and production speed at a glance, enabling quick fixes that reduce delays and save money.

Key Takeaways

Manual KPI tracking is slow and error-prone.

Dashboards provide real-time, clear views of key metrics.

This leads to faster decisions and better operational control.

Practice

1. What is the main purpose of a KPI dashboard in a SCADA system?

easy

A. To generate detailed reports for auditors

B. To store raw sensor data for later analysis

C. To control machine operations automatically

D. To display key performance indicators clearly and quickly

Solution

1. Step 1: Understand the role of KPI dashboards

   KPI dashboards focus on showing important numbers that reflect system performance.

2. Step 2: Differentiate from other SCADA functions

   Storing data, controlling machines, and generating reports are different tasks from displaying KPIs.

3. Final Answer:

   To display key performance indicators clearly and quickly -> Option D

4. Quick Check:

   KPI dashboard = clear key numbers [OK]

Hint: KPI dashboards show key numbers fast and clear [OK]

Common Mistakes:

• Confusing dashboards with data storage
• Thinking dashboards control machines
• Mixing dashboards with report generation

2. Which of the following is the correct way to highlight a KPI value that is below target using color in a dashboard?

easy

A. Use red color for values below target

B. Use yellow color for values below target

C. Use blue color for values below target

D. Use green color for values below target

Solution

1. Step 1: Understand color conventions in KPI dashboards

   Red usually signals a problem or below target performance.

2. Step 2: Match color to KPI status

   Green means good, red means bad, so below target should be red.

3. Final Answer:

   Use red color for values below target -> Option A

4. Quick Check:

   Below target = red color [OK]

Hint: Red means below target or problem [OK]

Common Mistakes:

• Using green for bad performance
• Choosing blue which is neutral
• Using yellow which means caution, not failure

3. Given a SCADA KPI dashboard showing machine uptime percentages: Machine A = 95%, Machine B = 88%, Machine C = 92%. If the target uptime is 90%, which machines should be highlighted in red?

medium

A. Machine B only

B. Machine A and Machine C

C. Machine A only

D. Machine B and Machine C

Solution

1. Step 1: Compare each machine's uptime to the target

   Machine A: 95% > 90% (above target), Machine B: 88% < 90% (below target), Machine C: 92% > 90% (above target).

2. Step 2: Identify which machines are below target

   Only Machine B is below the 90% target and should be highlighted in red.

3. Final Answer:

   Machine B only -> Option A

4. Quick Check:

   Below 90% uptime = red highlight [OK]

Hint: Highlight only below target values in red [OK]

Common Mistakes:

• Highlighting machines above target
• Including machines that meet or exceed target
• Ignoring the target threshold

4. You created a KPI dashboard but the color coding does not change when values go below target. What is the most likely cause?

medium

A. The data source is missing some sensor readings

B. The dashboard layout is too complex

C. The color rules are not linked to the KPI values correctly

D. The target values are set too high

Solution

1. Step 1: Check the color coding logic

   If colors do not change, the rules linking KPI values to colors are likely not set or connected properly.

2. Step 2: Rule out other causes

   Layout complexity or missing data won't directly stop color changes; target values affect performance but not color logic.

3. Final Answer:

   The color rules are not linked to the KPI values correctly -> Option C

4. Quick Check:

   Color rules linked properly = color changes [OK]

Hint: Check color rule connections first when colors don't update [OK]

Common Mistakes:

• Blaming layout instead of logic
• Assuming missing data causes color issues
• Thinking target values affect color coding directly

5. You want to design a KPI dashboard for a SCADA system that shows temperature, pressure, and flow rate KPIs. Which layout approach best supports quick understanding?

hard

A. Display all raw sensor data in a large table with no colors

B. Arrange KPIs in a simple grid with clear labels and color-coded status

C. Show only the average values without any target or color indicators

D. Use multiple pages with detailed charts for each KPI

Solution

1. Step 1: Identify best practices for KPI dashboard layout

   Simple grids with clear labels and color coding help users quickly see status and compare KPIs.

2. Step 2: Evaluate other options

   Raw data tables, averages without targets, or multi-page charts reduce clarity and speed of understanding.

3. Final Answer:

   Arrange KPIs in a simple grid with clear labels and color-coded status -> Option B

4. Quick Check:

   Simple, clear, color-coded layout = fast understanding [OK]

Hint: Use simple grids and colors for fast KPI reading [OK]

Common Mistakes:

• Showing raw data instead of KPIs
• Omitting targets and colors
• Splitting KPIs across many pages
