In this session I’ll show how we managed to create two manufacturing applications with around 50% of the code reused. Although it’s the same business line, the products are entirely different. You’ll see how we designed the database, middle tier, services and UI in the way that it’s possible to reuse it again and again.

1. CODE REUSABILITY

2. AGENDA
• How to design reusable components
• Implementation
• Deploy in an elegant fashion

3. ABOUT ME

4. REMEMBER THE LEGO?

5. WHAT WE KNOW ABOUT CODE
REUSABILITY?
• It’s complex to design, hard to write
and almost impossible to maintain
• It breaks when you need it the most
• It always ends up as framework

6. A PROBLEM OR A CHALLENGE?
• What’s the story?
• Two manufacturing systems
• Deadline approaching fast
• …but we had an idea 

PROS CONS
• No schema • Inability to use
changes standard tools for
• More reuse of a querying +
base system reporting
• Performance
issues around
serializing
(solvable)

10. YEAH BABY! NOW WE’VE GOT OUR
OWN FRAMEWORK TOO
• It is focused on a business problem
eg. Manufacturing Execution Systems
• It is extensible as much as you need

11. LET’S SEE IT RUNNING
DEMO

12. HOW ABOUT NEW VERSIONS KID,
HUH?
• Source Control (TFS)
• We have everything, but?
• Ever heard about NuGet?
• NuGet Server

13. LET’S SEE IT RUNNING
DEMO

14. SUMMARY
• We have seen how to design reusable
components
• Great example of implementation in a
new system
• An elegant way to package & deploy
them

15. THANK YOU!
