1 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl OReilly Open Source Conference 2000 Stephane Barde 7/19/2000

2 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl I - Value Added Information Channels -> Problem related to information flow management -> Creating the value added channel II - Perl: a key enabler of process re-engineering -> Resources use maximized with Perl -> Key Advantages III - Flat Files as a Central Data Repository: -> Dimensioning. -> Retrieving Data.

3 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl I - Value Added Information Channels What this is all about: Company standard processes generating information, that are not part of the core business, but generate important loss of productivity. Improve Efficiency Globally by Giving Value to the Information Examples: Travel Request and Booking Information Bug Tracking System Application Access Request New Employee Check Lists: how to get a new employee productive in a minimum amount of time.

4 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl A Typical Information Stack: the Approval Chain User Need Approval Detailed Information References User Manager Tech/Functional Support Buyer, Finance, Receiver... Different People Providing Different Pieces of Information Travel Request Departure/Return Date, Hotel, Car. Approval up to a certain amount. Overnight stay, in lieu off approval... Detailed Travel Info: Schedule, addresses... PO #, Invoice #, Folder #, booking #…

5 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl Financial Consolidation and Analysis Travel Requester Travel Booker Travel Approver A Small Company, one Department Travel Requester Travel Booker Travel Approver Department Travel Requester Travel Booker Travel Approver Department MS Excel !? A Small Company: Single Vertical Dimension Manual process -> time consuming, either the booker or the financial analyst spend time to consolidate data. Loss of Productivity on Administrative Tasks Multi-dimensional model: Processes are different within the organization. Consolidation end up being a nightmare as Data dont mean the same and are not handled the same way across the organization. A Typical Information Stack:

6 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl Issues with information Flow Management: How Efficient are You at Managing and Using Information? Do we (we = all users involved in the process) all talk the same language through the entire organization? Do we all use the same information pieces to complete a given action? Am I (I = anyone in the organization) able to report on given metrics globally (what is spent and how it is spend, what is the mean time to resolve a problem)? Can I easily aggregate the information I work on? Am I able to quickly retrieve the information I need to analyze, compare, and make the right decision at the right time?

7 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl Issues with Information Flow Management: Take advantage of the Information You Generate Consistency: No Systematic Processing. Consolidation: Someone Someday will have to put everything together to report on specific metrics. Accessibility: No searching capabilities, data not stored on a centralized repository. Capitalization: Any data repository is a potential wealth: Developing Analysis Capacity will enable to Gain Productivity, Sharpen your Strategy, Refine your Goals.

11 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl ITManagement Need for a Web Based Solution What Management says to the IT guy: We need to (re-)engineer this process. Youve got no resources, no money and no time. Just do it. When do you thing it will be ready? Time / Resource / $ ? II - Perl as a Key Enabler for Process Re-Engineering Will Do… with Perl Youre the IT guy! What Do You Say?

12 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl Perl Other Programming language Programmer Learning Curve Time Productivity Quick developer learning curve makes project staffing easier. Perl Key Advantages IT resources primarily focused on core business applications development and support. No time to waste in experimenting: need for efficient, documented, pre-existing solutions. Perl reminds of many other programming language. Quick Learning Curve. Lot of documented free resources available (CPAN). Perl is free and highly portable. Perl is low on Hardware Resources Short Implementation Timeline with Few Resources

13 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl Dealing with Data Perl makes Flat File a Good Solution for Web Based Processes Perl provides connectors to most of the database types. Perl has an efficient set of tools and libraries to develop solutions close to the users process: file processing, triggered email alerts, XML data parsing, synchronization with BackOffice… Flat files are a quick way to deploy centralized web based processes. They offer an efficient way to store information at no cost. Flat files present the advantage of being compatible with most software. For example MS Excel allows further analysis of raw data provided by flat file databases.

14 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl III - Flat Files as a Central Data Repository: Keep Files Size Small Flat file processing works fine up to 50k lines (and more) depending on the hardware and server workload. Well suited for low transactional volume: up to 200 transactions/day. Travel Request Example: 10.000 employees, 500 frequent flyers (2 trips/month). 2000 employees travel twice a year. => 14.000 rows per year (1k/line => 14 Megs) => flat files yearly split To increase search efficiency: archiving by splitting databases (temporal split / by data value). Have index files containing keywords and reference to static generated file.

15 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl data.csv Retrieving information Looking for ABC ……… ……... Search Results One Data Entry XML output dynamically generated XML template 2 full scans to retrieve the information needed XSL XML

16 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl ……… ……... travel.csv ……… travel_2000.csv File split: as the database size decreases, the search is more efficient. Reducing Response Times: File Split Example: yearly split of the master data file Natural Way to Decrease the Size of the File Parsed

17 Simplifying Company Processes with Perl Stephane Barde Arthys / Ezperl data.csv Looking for ABC ……… ……... Search Results Static XML with Ref # Ref # XML ……… ……... data.csv XML 1 database entry is associated with 1 static XML file. XSL Reducing Response Times: Static Display Processing Allocated to Data Search
