Introduction
• Leif Singer, PhD Student in Software Engineering
• Software Engineering is Processes, Practices and Tools– Waterfall, Agile, XP, Lean– Architecture, Design Patterns– Information Flow in Projects– Model-Driven Development
• me: End User Development (EUD)
• Position Paper: Work in Progress

Introduction
• IT Projects in Enterprises: expensive, take a long time
• Actual Needs: right here & right now, I need to combine data from these three systems to do my job better today!– There must be a Long Tail here ...
• Excel fills this gap! – but badly (much copy & paste between systems)
• Needed: a tool for end-user-driven enterprise integration– Sorry.

Introduction
• Different Approaches for EUD Mashups– most workflow-based, e.g. Yahoo! Pipes
• What about Business Users? – They know Spreadsheets! – exisiting, proven approaches (Karma, Mashroom, Spreadmash, ...)
• Halbert: spreadsheets don’t switch between programming & runtime– no need to visualize program flow– less of a cognitive burden on non-programmers– Tuchinda et al.: Spreadsheet Mashups better understood than workflow
mashups (by end users)

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Introduction
• How to build a Community of Mashup Creators – in an Enterprise Setting?
• Tools are not enough, need sociotechnical approach
• with Tools that– are easily accessible– connect users
• Users themselves determine their Engagement– use superficially: like Excel on the Web– use it to mix Services: as a simple Mashup Editor– use it to create new Tools!

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Introduction
• Nardi specifically on Spreadsheets:– Formulas are accessible by all– Macros used by Tinkerers
• A layered approach for a Mashup Editor? – Macro Language for Spreadsheet Mashup Tool
• Great Example: Surveys from Google Docs– Spreadsheets + a Survey-Layer on top– also: see Keynote, Google Apps Script in Spreadsheets :)

Introduction
• But what good is such a tool if everyone works in isolation?
• Fischer et al.: Users will work together when finding out they are working on similar Problems
• Use Social Software to improve the Awareness between Coworkers

Like
I just created a new Mashup: Sales Report 2010. Take a Look!

A SCENARIO
12
![Page 13: Towards Communities of Practice for Mashups](https://reader034.vdocument.in/reader034/viewer/2022051816/5458ab83b1af9f37608b539f/html5/thumbnails/13.jpg)
Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
A Scenario
• People copy and paste stuff from enterprise systems into Excel all the time– enable them to directly include them– less error-prone, much faster
• Mrs. Miller: sales person, writes personal letters to her best customers– uses ERP system to find those– uses CRM tool to find their addresses– copies addresses into spreadsheet, sends emails
13
![Page 14: Towards Communities of Practice for Mashups](https://reader034.vdocument.in/reader034/viewer/2022051816/5458ab83b1af9f37608b539f/html5/thumbnails/14.jpg)
Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
A Scenario
• Creates a mashup that collects all that data for her– SNS automatically generates message
• Her contact Mr. Slater sees the messages– takes a look – has no use for it, but likes the idea: clicks “like”
14
Like
Mrs. Miller: I just created a new Mashup: My Best Customers. Take a Look!
Like
Mrs. Miller: I just created a new Mashup: My Best Customers. Take a Look!
![Page 15: Towards Communities of Practice for Mashups](https://reader034.vdocument.in/reader034/viewer/2022051816/5458ab83b1af9f37608b539f/html5/thumbnails/15.jpg)
Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
A Scenario
• Mr. Smith is a contact of Mr. Slater, gets noticed of “like”
• Takes a look, thinks it would be useful– clicks “make my own copy”– changes zip code, names it “Best Customers for Birmingham”
• Mrs. Miller is is happy other people find stuff she made useful
15
Mr. Slater: I just liked a Mashup: My Best Customers.
Mr. Smith: I just copied the Mashup My Best Customers to a new one: Best Customers for Birmingham

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
A Scenario
• Mr. Smith is a tinkerer, plays with Mashup tool, finds macro language– writes a macro that will send the email for him
• Mrs. Miller gets notified
• Cherry-picks the changes she wants (see GitHub.com)– need (semi-)automatic creation of independent commits (see e.g.
Hayashi and Saeki 2010)
16
Mr. Smith updated his Mashup Best Customers for Birmingham: “Send Email automatically”
Apply Change to My Best Customers?

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Remaining Tasks
• Categorization of Service Types– different requirements & uses
• Task Services– current VAT, Decision Services – possibly delayed, tied to roles, ...
• Entity Services– e.g. CRUD Operations
• Process Services– Processes have a State; User must be able to proceed in Process
• Feed Services– e.g. for the SNS Timeline
24

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Remaining Tasks
• Wrapper Services / Adapters
• some examples already developed (SVN, Trac, Feeds, ...)– from our domain
• Insight into real-world enterprise systems is missing– not easy to obtain
• An Approach for Adapters– not single technical solutions
25
![Page 26: Towards Communities of Practice for Mashups](https://reader034.vdocument.in/reader034/viewer/2022051816/5458ab83b1af9f37608b539f/html5/thumbnails/26.jpg)
Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Remaining Tasks
• Mashup Editor still barebones– clean up needed– Macro Language– Visualizations of Results
• How to use the Service Types in the Editor? – can you create process mashups that users can then click through?

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Closing
• A Spreadsheet-based Mashup Editor– supporting a Macro Language– integrated into a company-internal Social Network Site
• Make the Company’s Resources available via adapters– so End Users can do Data Integration
• Use Mechanisms from Social Software to build and support a Community of Practice for Mashups
28

Leif Singer: Towards Communities of Practice for Mashups Dec 1st 2010
Discussion
• “Tools for making Tools”– More useful, more potential than mere problem solutions– Able to solve Problems that are still unknown– No Support in Mashup Editors for End Users? Google Spreadsheets!
• Have a Story on opening up Enterprise Silos? – Data Integrity, Confidentiality
• How to use Social Mechanisms in Research? – Do I have to prove the “Like”-Button works to use it?
• raise your hand or drop me a line :)– [email protected]– twitter.com/lsinger

Thank you for your attention!
