NPC moving on the same tile instead of walking around?

Hi there, I'm using this script on a character, which should make them randomly move and for the most part it works, however they are walking and only changing direction, instead of moving off the tile and walking around? Here's the script:

 public float directionChangeInterval = 1;
 public float maxHeadingChange = 30;

 CharacterController controller;
 float heading;
 Vector3 targetRotation;

 void Awake ()
 {
     controller = GetComponent<CharacterController>();

     // Set random initial rotation
     heading = Random.Range(0, 360);
     transform.eulerAngles = new Vector3(0, heading, 0);

     StartCoroutine(NewHeading());
 }

 void Update ()
 {
     transform.eulerAngles = Vector3.Slerp(transform.eulerAngles, targetRotation, Time.deltaTime * directionChangeInterval);
     var forward = transform.TransformDirection(Vector3.forward);
     controller.SimpleMove(forward * speed);
 }

 /// <summary>
 /// Repeatedly calculates a new direction to move towards.
 /// Use this instead of MonoBehaviour.InvokeRepeating so that the interval can be changed at runtime.
 /// </summary>
 IEnumerator NewHeading ()
 {
     while (true) {
         NewHeadingRoutine();
         yield return new WaitForSeconds(directionChangeInterval);
     }
 }

 /// <summary>
 /// Calculates a new direction to move towards.
 /// </summary>
 void NewHeadingRoutine ()
 {
     var floor = Mathf.Clamp(heading - maxHeadingChange, 0, 360);
     var ceil  = Mathf.Clamp(heading + maxHeadingChange, 0, 360);
     heading = Random.Range(floor, ceil);
     targetRotation = new Vector3(0, heading, 0);
 }

} Any and all help would be appreciated, especially if you could detail what you've done and why! :)
