Testing : Give me five common problems that occur during software development .

Poorly written requirements, unrealistic schedules, inadequate
testing, adding new features after development is underway and poor
communication.

1. Requirements are poorly written when requirements are unclear,
incomplete, too general, or not testable; therefore there will be
problems. 2. The schedule is unrealistic if too much work is crammed
in too little time.
3. Software testing is inadequate if none knows whether or not the
software is any good until customers complain or the system crashes.
4. It's extremely common that new features are added after
development is underway.
5. Miscommunication either means the developers don't know what is
needed, or customers have unrealistic expectations and therefore
problems are guaranteed.
