Based On How Professional The Company Name

I Own Several Companies – I Have Had Custom Software Written Before

I Estimate That This Application Will Cost Me ~$120,000

Some Of My Colleague’s Experiences With Custom Software Were Smooth

Sailing But Many Were Disastrous

My Business Classes Encourage Risk Management!

Loss?

Risk Management : Pay $9,000 For $4,800 Worth Of Software Hoping Not To Pay $120,000 For Poor Software

As You Present Your Prototype, Part Of Your Job Will Be To Convince Me That You Offer The Best

Solution For My Business

It Is Important To Me That My Software Design Company Anticipate My Needs

It Is Important To Me That My Software Design Company Understand My Business

Before Your First Meeting:

Google Search

Business Journals

Review Their Website

Review Competitor Websites

Etc.

Many Video Stores Are Closing Their Doors (Failure!)

You Should Ask YourselfWhy Are Video Store Going Out Of Business

Web Search – Business Journals – Etc.

Even Asked Some Friends At DinnerWhat Do You Not Like About Going To A

Video Store? What Would Make The Experience More Rewarding?

“It takes too long to find a movie. I read 300 boxes before I find one I want. There is never anyone to help much with my search needs.”

“ I rent the same movie more than once; there needs to be some way for them to easily tell me if I am renting the same movie.”

Video Store? What Would Make The Experience More Rewarding?

“I waste at least half an hour to forty-five minutes looking at the same movies each time I go.

“I wish there some way to print a list of the available mysteries so that I could check them off as I see them.”

Even Asked Some Friends At DinnerWhat Do You Not Like About Going To A

Video Store? What Would Make The Experience More Rewarding?

“I sometimes go and find nothing! Frustrating.

“It costs too much. There needs to be more flexible return dates.”

“I wish there were some way to see my account – what I have previously rented.”

Design 3 – You Can Extract Related Copy Info To Web Or Stand-A-Lone Applications

Movies

MoviesSELECT *FROM Movie, MovieItemWHERE (Movie.ID = MovieItem.MovieID) AND (Movie.ID = 12331)

Your prototype must include one sample data entry. You can use the text property to initialize it.

We would normally use the DataGridView to fill in the information about the Copies.

Since most of you would rather not add the database, you can create a prototype that simulates the table view with textboxes. Explaining to the Stakeholder that it will later look a bit more like a table with scroll bars.
