stages plan system project:
1. determine aim, planning with tactics companies.
2. identify system projects
3. decide system projects target
4. decide system projects obstacle
5. menetu system projects priority.
6. make system design report.

will prepare system projects that be developed

2. announce system developers project

define system projects that developed
thereby task that must be done by team analysis in this stage:

3. evaluate system project feasibility,
4. make project proposal,
5. ask management sanctions.

do feasibility study
feasibility study a study that be used to menetu is system development proper at go on
or at stop. this watchfulness aims unuk:

2. determine system user needs marginally to can achieve these system target.
3. determine troubleshoots that so that old ones system not yet can achieve aim.

evaluate system project feasibility
five feasibility that can considering:
1. technique feasibility
