@Asterix probably you would need to describe a bit what you’re trying to get with this post. The wording of the topic is way too general .

You might find the answers in the Technical Documentation here:

@Asterix, Marcel is right, this is a fairly broad question, but typical areas where I have seen assumptions include:

• Company commitment / project sponsorship
• Scope inclusions / exclusions
• Ability to adapt processes to standard IFS / keep the same
• Critical requirements to be addressed / handled another way
• CRIM items (customization, reports, interfaces, mods)
• Data cleansing and restructuring requirements
• Resource availability / constraints
• Competing demands for time / other projects
• Technology stability / changes expected

I hope this helps. Chris
