5 common problems in the software development process

• Poor requirements - if requirements are unclear, incomplete, too general, or not testable, there will be problems.
• Unrealistic schedule - if too much work is crammed in too little time, problems are inevitable.
• Inadequate testing - no one will know whether or not the program is any good until the customer complains or systems crash.
• Featuritis - requests to pile on new features after development is underway; extremely common.
• Miscommunication - if developers don't know what's needed or customer's have erroneous expectations, problems are guaranteed.

Define usecase and testcase?

UseCase :
It is indepth detailed description about Customer
Requirments. it is developed from BRS/SRS. it is prepared

Testcase:
It is a doument describing the input,action and
expected response to determine wether the application is
working correctly according to the customer requirments.
it is derived from srs,usecases and test scenarios. while
developing test cases we can find gaps in the requirments
also.

Use case is a set of scenario's of User requirement.
Test Case is a document Designed based on the Use case
To Evaluate between Expected & Actual Result.

USE cases is a pictorial representation of requirments.
