Phone number length allowed to be more than 20 digits long

[jevan13]

• Should guard against this error
• Set a reasonable length limit such that if the length of phone number exceeds it, it is obvious it has been incorrectly entered
• Causes inconvenience if user accidentally inputs a long phone number, and is unable to retrieve the actual phone number through the application

Team's Response

If the problem happens only in case of a deliberate sabotage (e.g., user entered a 30-digit telephone number), it will not be considered a bug (in our context).

The above was found in the CS2103 PE guide.

In addition, we changed this to low as we feel that it is almost impossible for someone to "incorrectly" type such a long phone number, as it requires the user to explicitly type out a lot more numbers than intended. To be considered a feature flaw, "Some functionality missing from a feature delivered in the current version in a way that the feature becomes less useful to the intended target user for normal usage." However, this is not normal usage, and is deliberate sabotage, as elaborated on in the extract from the CS2103 PE guide.

:question: Issue response

Team chose [response.Rejected]

• [x] I disagree

Reason for disagreement: Hi, maybe the example I used was too extreme, but my point as explained before was:

• Quoted, "Set a reasonable length limit such that if the length of phone number exceeds it, it is obvious it has been incorrectly entered"
• This is likely to happen, as users have a lot of data to enter, and may sometimes input one or two too many numbers
• For example, since this application is targeted towards the governmental agency in Singapore, it it reasonable to set the limit of phone number to 9, so that users will know when the number is incorrectly entered (Singapore phone numbers are 8 digits long)

## :question: Issue severity Team chose [`severity.Low`] Originally [`severity.Medium`] - [x] I disagree **Reason for disagreement:** Given that this application has to handle a large amount of data, typing in all the informations (name, NRIC, email, phone number, etc.) can likely cause this issue to happen. It would be nice if the application could guard against it to reduce inconvenience to users.
