Error Prevention of sriwijayaair.co.id

Error prevention

"Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action."

A good systems, applications, or websites should consider to use this guidelines, by preventing user from error, rather than fixing the error (even though fixing these problem is also necessary) because what? People are scared with error.

Sriwijayaair.co.id has many of them, but in order to keep my time efficient, I'll be giving you two of them and it's basically from wrong style of designing the website.

1. Search button are always enabled.

You can still search for a flight schedule without inputting the destination and arrival route and system will give you alert about the mistake you've just made. It's frustrating, because I am alerted and we would likely wondering what we're doing it wrong :')

Pict 1. Clickable search button

And you'll be given some of this...

Pict 2. The alert that shows

Recommendation: Disable the search button when user haven't inputted the destination and arrival route.

It's kinda disaster, and it's 4/4 for Severity Rating from me. fix, bay, fix!

2. Searching Office does't really search

When you want to look for this airline office, you can simply click the Office link below the site and you'l' be directed to Office site. But here our problem comes.

When you apply some filter region like this...

Pict 3. Filtering region by Jakarta area

First thing you'll notice, it doesn't give you a processing throbber which kinda against the rule of Visibility and System Status. Then you'll be given some information about the airline office located in Jakarta region. but... when I apply the filter like this...

Pict 4. Jakarta with Denpasar as the city

The system actually are in error state, because Denpasar is located in Bali instead of Jakarta. Heck! the system even couldn't inform us what we're doing wrong.

Recommendation: Give the error, for better result, just change the select option type with field and improved by adding area suggestion

Severity Rating? 4/4

Thanks. Winter Deadline is coming.
