52. How and Why of 'ERP Failure‘

53. Cost overrun while implementing Schedule go haywire Quality is falling short of user expectations Lack of preparation ERP requires massive efforts in short span of time Consultants from implementation partners arrived to start “as is” study of existing business process and the company cannot spare the key users to spend adequate time with the consultant. Needs good planning and scheduling Ensure that right person is available at the right time Senior – experience – person should spend time to spell out the business processes and requirements If the ERP implementation is initiated without proper planning, trouble is inevitable How & Why of ERP Failure

54. Lack of top management commitment Faulty selection process Ignorance of the human aspect A negative attitude or a negative mind-set in the user community can adversely affect the success rate of the ERP package » Training and education to create the right mind-set and a positive attitude towards ERP is required » Fully integrated systems demand change in the work pattern How & Why of ERP Failure

55. Too high expectation Unrealistic expectation will create problem » Find out what ERP will NOT do » User who actually have to key-in business transactions often complain about slow response for screen updates and longer time to enter the data » Check infrastructure – RAM, CPU speed, etc. Too much customization ERP packages are tightly integrated Making change in source code at one location may result in snowballing effect in other modules within ERP. New version comes with new features – but if too much changes are done, you can not accept new version….. Keep the customization minimum – do only ‘essential customization’ How & Why of ERP Failure

56. Improper implementation Most cases the software package is OK Wrong implementation is responsible for unsatisfactory results Mistakes in implementing a good ERP package turns dreams into nightmare and results in considerable investment and efforts going down the drain How & Why of ERP Failure
