03 Scenarios

Scenario 1 (Novice User)

Jane wants to make a large batch of spicy chili to take to work for the week.  She loads Spatula and looks up ‘spicy chili’, finding a great sounding recipe for Spicy Beef Chili.  She prints out the ingredients she’ll need and takes her list to the store to pick up the items.  She loves that the items are already sorted by what part of the store they’re located in.  She has a hard time finding the habanero peppers she needs, but then sees on the recipe sheet that they might be called a Scotch bonnet, and could be substituted with a Serrano or Anaheim pepper.
Upon returning home, she still has the recipe open on her laptop, which she takes into the kitchen to start cooking.  She clicks the  “Cook with Me” button to open the cooking dashboard.  As she completes the steps, she uses her elbows to progress through the recipe.  When she reaches the point where she has to brown the onions for 5 minutes, the dashboard automatically starts for a timer for her.  5 minutes later, an audible alert notifies her that the onions are done.  When she gets to the step where she adds the pepper, she notices that there’s a highly ranked tip telling her that doubling the pepper really kicks it up a notch.   She finishes the chili, finding it delicious.  Two hours later, she receives an email from Spatula, prompting her to rate the recipe she just made.  She obliges, and rates the chili as a 4 out of 4, and gives it a difficulty rating of “Medium”.


Scenario 2 (Expert User)

Alex has a free day and decides to indulge in some classic French cooking.  He looks up a recipe for coq au vin, and finds one that satisfies what he’s looking for.  Because he was logged in, the system noted that he looked at the recipe last.  Alex heads out to the grocery store and opens the app on his iPhone.  Because he’s logged in, the coq au vin recipe he was looking at before is automatically loaded.  He presses the “Get Ingredients” button and loads the ingredients view.  With this view he’s able to wander through Whole Foods finding the ingredients he needs, and checking them off as he picks them up.  To his disappointment, they’re out of the crimini mushrooms that the recipe calls for.  He clicks the “more info” button for criminis and is given a list of substitutes.  He notes that the store has the suggested substitution of shiitake mushrooms, and picks those up instead.  Having all the required ingredients, he heads back home.
At home, he opens Spatula on his MacBook Pro.  He adds the Coq au Vin recipe to a new meal, and then finds a recipe for homemade egg noodles and adds that to his meal.  He then clicks “Cook with Me”.  Because the coq au vin takes much longer than the egg noodles, only the coq au vin is displayed at first.  He then prepares all the ingredients.  As he starts cooking, he reaches a step where he has to simmer a marinade base for 15 minutes.  He starts the online timer, and then goes to see what his kids are upto upstairs.  From there, he can check the timer using his iPhone app which is synced with the online timer.  Once simmering has completed, he returns downstairs to continue cooking.  By this time, he can start working on the egg noodles in parallel so that both recipes finish at the same time, and the recipe appears alongside that for coq au vin.  The coq au vin recipe is nearing the end, and the final timer starts for the last simmer of the sauce.  Simultaneously, he tosses the completed egg noodles into boiling water and a second timer starts.  Alex eats his delicious meal.  The next day, he sees the email from Spatula asking him for his rating. He rates it 3 stars – not bad – and marks it as ‘difficult’.  
He also adds a tip – the 06 Barbarossa Shiraz worked great in the recipe.
