Insufficient Grouping
^^^^^
**Definition:**

* A module or group contains too many elements. Especially for large modules, groups should be used to add logical structure to the module and enhance readability. If a group reaches a critical size, it can be structured further by subgroups.


**Code Example:**

.. code-block::

 module InsufficientGrouping {
  type record myRecordType1 { // . . .
  }

  type record myRecordType2 { // . . .
  }

  type record myRecordType3 { // . . .
  }

  type record myRecordType4 { // . . .
  }

  type record myRecordType5 { // . . .
  }

  template myRecordType1 myTemplate1 := { // . . .
  }

  template myRecordType1 myTemplate2 := { // . . .
  }

  template myRecordType1 myTemplate3 := { // . . .
  }

  template myRecordType1 myTemplate4 := { // . . .
  }

  template myRecordType1 myTemplate5 := { // . . .
  }

  function f1( ) { // . . .
  }

 // more declarations here
 }
