Background: Eventually in a hypothetical corporate enterprise environment that I refer to, people who 'pay' for the application never use the applications developed. The main consideration is always about cost cutting on how cheap the department can run in the short to medium term (forget about long term).
OT without extra pay is always a norm and rather expected so no need to discuss the cost saved due to time. Turnover is always high and I doubt better UX will help much.
Yes the management appreciates good CSS and styling but always prefer web app that looks like SAP / excel spreadsheet anytime of the day.
Giving the fact corporate is a cost center, how I can justify spending extra effort in UX aspect of the corporate applications. In addition, to what extent the effort for better UX should be? (e.g. hire external consultant, put another 1000 pages guidelines, hire a CSS/JS developer, create a department specially for UX - "another layer of bureaucracy")
