2. Intention driven Early – Late requirements engineering

3. Intra-Agent view perspective of software engineering
• Social -- who are the relevant Enterprise Goals
actors, what do they want? Intentional Features
What are their obligations? Goals
What are their capabilities?
• Intentional -- what are the Raised by
relevant goals and how do
they interrelate? How are they Enterprise Processes
being met, and by whom? Actors Roles
• Process-oriented -- what are
the relevant
business/computer processes? Supported by
Who is responsible for what?
Enterprise Systems
• Object-oriented – what are
the relevant objects and Components
Operational Features
classes, along with their inter-
relationships?

// Presentation Layer

{purpose
{ feature PetName to sessionID ;
feature PetDesc to sessionID;
feature PetLocation to sessionID;
} actuation { // call the presentation layer
call BaseLanguage.Csharp(”searchPL.dll”,

13. Pets Search Task Definition
task SearchPets with NString sessionID
// Presenting system as an actor for late
requirements
{actor PetShop}{mode achieve}
//GORE requirements
{ requirements { //resource requirements
needPetName:require sessionID.PetName;
needPetDesc:require sessionID.PetDesc;
needPetLocation:require sessionID.PetLocation;
//task requirements
queried:require
Database.Searching(sessionID);}}
