Draw-down or delivery test: is the tank producing enough hot water to match size of tank?
"Residential water heater can deliver 70% of tank capacity at the thermostat setting minus 20 degrees.  What does this mean?  If the thermostat is set on 120 degrees, the unit should deliver 70% of tank volume at a temperature between 100 degrees and 120 degrees."

Steps:  Turn off heater. Connect hose to drain. Run hose into 5 gallon bucket.
With a 50 gallon tank. Expect minimum 70% or 35 gallons of hot water before it starts to cool.  Run water fast before it cools.
If result shows correct amount of hot, then tank is functioning, and plumbing becomes a suspect.
First shower in morning does not get very hot water.
This might be 'deadband' issue caused by a variation in thermostat calibration. Deadband is temperature difference between burner shut-off and when water has cooled enough to come back on.
Typically the problem of thermostat calibration is considered 'normal' by water heater manufacturer's. Spec sheets say water temperature inside lower part of tank can drop 20-30F before thermostat turns on burner, and during periods of usage, the top of tank generally stays hot and the calibration is not noticed.
However, if no hot water has been drawn from tank for several hours, the entire tank can cool down. Result: first usage in morning seems cool by comparison.

LESS hot water: Tank has some hot water
a) If tank has some hot water, then following suspects are eliminated:
Red reset button is good, upper element is good, Circuit breaker is not tripped on one leg.

Quick answer: Turn power OFF: Test/replace lower element:  How to test element   Replace element
Power is OFF: Replace both thermostats How to replace thermostats

Causes include:
1) Check for under-voltage. Action: Test across top two screws on upper thermostat for 208-240Volts  How to test water heater circuit
Water heater will work with any voltage, but will heat slower with undervoltage. Read more   Calculate recovery
2) Temperature needs to be set higher, especially on lower thermostat. Action: Adjust temperature
3) Bad upper or lower thermostat. Actions: Replace both thermostats
4) Leaking tank has caused rusted parts. Inspect elements. Check for leaking. Leaking water heater
5) Water leak running hot out of tank. Turn off all taps and put ear against hot pipe
6) Bad lower element and sediment build-up. Action: How to test element. How to replace element and clean out sediment.
7) Loose wires. Action: Look for signs of burning and high heat. Cut back wire & Test wire for continuity as shown in next step. Replace part connected to burned wire.
8) Defective wire between upper and lower parts of tank. Action. Replace both wires from top of tank. How to wire thermostats
9) Broken dip tube letting cold water enter upper tank. Actions: Remove cold water nipple and pull out dip tube for inspection. Look for bits of plastic in aerator. Read broken dip tube
10) TP valve is running hot water out of tank, leaking faucet, broken pipe. Action: Turn off all water. Listen for sound of running water. How to test and replace TP valve
11) Bad single-handled faucet cartridge or check valve  Test for crossover
12) Family consumption is higher than before  Ways to increase amount of hot water
14) Direct-return Recirculation system doesn't not have check valve. recirculation system

LESS hot water: Tank has some hot water

1) Low gas pressure. Observe other gas appliances Check gas pressure
2) Thermostat out of calibration   Troubleshoot gas control valve    How to replace thermostat
3) Temperature needs to be set higher, especially on lower thermostat. Action: Adjust temperature
4) Broken dip tube letting cold water enter upper tank. Actions: Remove cold water nipple and pull out dip tube for inspection. Look for bits of plastic in aerator. Read broken dip tube
5) Water leak running hot out of tank. Turn off all taps and put ear against hot pipe
6) TP valve is running hot water out of tank, leaking faucet, broken pipe. Action: Turn off all water. Listen for sound of running water. How to test and replace TP valve
7) Bad single-handled faucet cartridge or check valve  Test for crossover
8) Family consumption is higher than before  Ways to increase amount of hot water
9) Dirty combustion parts Clean combustion chamber
10) Direct-return Recirculation system doesn't not have check valve. recirculation system
