-2 - My Example: Pet Dating Service The problem: Dog owner wants puppies, but not just ANY puppies. * How to find the appropriate father? * What’s in it for him? dogsindepth.com

-3 - The Steps 1.Identify stakeholders 2.Write one “user story” per stakeholder 3.Identify use cases and provide written descriptions & diagrams 4.List requirements for each use case, and for overall system 5.Establish measurable goals 6.Sketch a wireframe “mock-up” to show the client paragonventures.com

-4 - Stakeholder Identification "Who cares?". Owners of female dogs Owners of male dogs Veternarians who may conduct health exams Breed associations who keep records Site owner/operator Truelegends.coml

-5 - Stakeholder Identification: (Grading?) Are all the obvious stakeholders identified? Are they distinct? (e. g. not just “Dog owners”) Truelegends.coml

-6 - User Stories Short enough to write on a 3" x 5" card. As a, I want. Example: As an owner of a female dog “Princess Leia”, I want a perfect litter of puppies, so that I can keep one and sell five of them for $1000 apiece. Cs.rochester.edul

-7 - User Stories Short enough to write on a 3" x 5" card. As a, I want. Example: As an owner of a male dog “Han Solo”, I want a puppy and some income to help pay for Han Solo’s vet bills. Cs.rochester.edul

-8 - User Stories Short enough to write on a 3" x 5" card. As a, I want. Example: As the site owner, I want to earn $50,000 or more per year through the sales of advertising on the site, and through user fees. ((Also we need user stories for the other two stakeholder classes)) Cs.rochester.edul

-9 - User Stories: Grading Does it follow the pattern? As an xxxx I want yyyy Is it brief (30 words or less)? Is it clear? (can you tell when it is achieved, without complex judgement calls?) Cs.rochester.edul

-10 - Use cases: It is a single KIND of interaction with a system We define Use Cases to help design User Interfaces The Use Case does NOT explain. It just identifies – The actor or actors The activity UC is the first step in Analyzing the User Story

-11 - Use Cases: Written form Female dog owner: (1) enter description of my dog into the system (2) scan descriptions of available male dogs (3)verify male dog’s pedigree (4)verify your own dog’s health (5) negotiate a breeding contract (6) carry out the breeding (7) provide feedback for future users

-12 - Use Cases: Grading Female dog owner: (1) enter description of my dog into the system (2) scan descriptions of available male dogs (3)verify male dog’s pedigree (4)verify your own dog’s health (5) negotiate a breeding contract (6) carry out the breeding (7) provide feedback for future users Every stakeholder has at least one use case Use cases are well described and thoroughly cover the subject

-13 - Use Cases: Grading Female dog owner: (1) enter description of my dog into the system (2) scan descriptions of available male dogs (3)verify male dog’s pedigree (4)verify your own dog’s health (5) negotiate a breeding contract (6) carry out the breeding (7) provide feedback for future users Every stakeholder has at least one use case Use cases are well described and thoroughly cover the subject

-14 - Use Case Diagram: Owner of Female Cs.rochester.edul Owner of Female dog Enter description of female dog Scan male dog descriptions Verify your dog’s health Vet Association Verify pedigree Owner of Male dog Carry out breeding Negotiate Contract Provide feedback

-15 - Use Case Diagram: Grading Owner of Female dog Enter description of female dog Scan male dog descriptions Verify your dog’s health Vet Association Verify pedigree Owner of Male dog Carry out breeding Negotiate Contract Provide feedback Correct users for each case

-16 - Use Case Diagram: Grading Owner of Female dog Enter description of female dog Scan male dog descriptions Verify your dog’s health Vet Association Verify pedigree Owner of Male dog Carry out breeding Negotiate Contract Provide feedback Draw little people (it’s part of the standard!)

-17 - Use Case Diagram: Grading Owner of Female dog Enter description of female dog Scan male dog descriptions Verify your dog’s health Vet Association Verify pedigree Owner of Male dog Carry out breeding Negotiate Contract Provide feedback Full text is NOT required (just titles of cases)

-18 - Requirements Lists GENERAL requirements, and CASE BY CASE requirements GENERAL requirements for the dog breeding registry: All users must register; addresses must be verified Users must be offered clear guidance to classify themselves owner of female; owner of male; vet Costs to users (if any) must be clearly stated up-front * Relations with AKC, other breed associations must be negotiated (they probably don’t want to be ‘registered users’.

-19 - Requirements Lists: An example OWNER OF FEMALE: Case=Enter description of female dog Required fields: Name Breed (pulldown list of AKC recognized breeds+”mutt”) Age Temperament (pulldown list) Name Weight Owner’s statement (text description of what is wanted.)

-20 - Requirements Lists: Grading At least one requirement for every stakeholder and use case Requirements are well thought out and thorough

-21 - Measurable Goals Lrn.usace.army.mil Our site will have at least 100 registered users by 90 days after site launch. Our site will generate 500 hits a week by 120 days after site launch. Our site will generate $2000 a month in AddSense revenues by 180 days after site launch. User satisfaction will be 3.5/5 or better at all times.

-22 - Measurable Goals; Grading Numbers to compare to measurable quantities Our site will have at least 100 registered users by 90 days after site launch. Our site will generate 500 hits a week by 120 days after site launch. Our site will generate $2000 a month in AddSense revenues by 180 days after site launch. User satisfaction will be 3.5/5 or better at all times.

Mockups and Prototypes Not required for Round 1 (Cross-team) Requirements For Round 2 (presented in Oct) we want to see a simulated step-by-step of how each STAKEHOLDER would use the site to conduct two key USE CASES
