6. Forming Solutions For Customers
From a blank screen to a solution
Most Training material available on Lightning Component
Development is very workshop-like in nature.
To Deliver Components to Customers, there are a
number of considerations
User Interface & Customer Acceptance
Component Design & Data Integration
Creating Bridges between Administrators and Customers

7. User Interface Design Rapid Prototyping using SLDS, HTML and SASS
An excellent tool introduced at Dreamforce 16 by the SalesforceUX team
Workshop:
Github:

8. Lightning Design System Starter Kit
Rapid Prototyping using SLDS, HTML and SASS
Has replaced Balsamiq Mockups in making mock screens for our clients
Provides a near-final mock-up of the solution that is easily changed
Provides HTML and mark-up for the Components

9. Lightning Design System Starter Kit
Rapid Prototyping using SLDS, HTML and SASS
Demo
Can be deployed to Heroku (with Username and Password authentication) or customers to view, discuss and provide feedback before development starts.
Webinar:
Nunjucks:

10. Lightning Design System Starter Kit
Rapid Prototyping using SLDS, HTML and SASS
Updated in Spring 17
Sharing json data among pages has
been added.
Any improvements to SLDS can be added
(eg) Utility Bar

11. Component Design Factors to Consider Structural Components
Components should be as small as possible
Sandbox a specific function
 Simplify your code!
Allows developers to separate out work
Should make testing more efficient
Re-usability is the primary reason to create a component.
..but Cost/Benefit and Deliverability are factors too!
Development of components (and events) takes time (and cost)
Re-usability  where can my component be useful?

15. Developers! Build Bridges!
... Code for the overall solution
The Setup menu remains the Salesforce platform’s key feature set
Developers are required when a requirement cannot be provided via the setup menu
The answer is no longer – ‘Make a Visualforce Page’!
Replacing entire screens.
Maintenance costs.
Breaks the relationship between the Administrator and the Customer.
With Lightning, a Developers Role is now to enhance the solution
and not replace it with customised code.
