Bpm Camp Prashant Web App Vs Process

Web Application or Process ? Case Study Prashant Gadgil

Characteristics of process looking like a WebApp or vice versa
Business Requirements
Modeling Options
An Implemented Solution
WebApp or Process? Outline

Lot of data involved - typically coming periodic batch job from external source or SOR
Difficult to define an instance to satisfy all participants
Different participants need to view this data sliced in a different perspective
Pieces (rows) of this batch data can be “referred back” independently as part of process
Business needs to update/change their process input anytime after the fact and that should again trigger tasks accordingly
WebApp or Process? Typical characteristics

High volume of number of rows possible in a batch
Minimal Tasks/clicks for users each day covering all data
Due to physical time constraint or deadline to complete a step
Process input or decision by a user is time consuming but it really applies to multiple rows
No bottlenecking on any user – turnaround time of each row is important
Complicated reporting of every detail of each row from outside the process context
Users can likely make mistake in decision and would like to correct their decision at any point in time
To be implemented in TeamWorks
WebApp or Process? Business requirements

1000 orders imported in a system as a nightly batch
3 Participants in Process:
Customer Service wants tasks one per State
Manufacturing wants tasks one per Manufacturing plant location
Shipping wants tasks one per Shipping Carrier
An order can be any combination of the above 3 parameters
Each participant gives some input/decision on each row of data
WebApp or Process? Data Example

Instance at lowest possible row (order) level
WebApp or Process? Modelling Options

Row Level Instance
Typical Process Model
Process for each row can flow independently
Too many tasks per Participant, one per order per participant, Too many clicks
Difficult to make decision on a subsection of orders inside one task e.g. across a certain state or manufacturing location or shipping carrier
WebApp or Process? Modeling Options

Traditional One Instance at Batch Level
One Multi-instance loop task per participant
Efficient entry of decisions across multiple orders
“ Process” for Individual row cannot move forward until all rows are completed at any step by the participants
One user can bottleneck the whole process for the entire batch
WebApp or Process? Modelling Options

Polled Instance for the whole batch of data
WebApp or Process? An Implemented Solution

Polled One Instance at Batch Level
One instance created for the batch of rows
All data externalized with bpd_instance_id in tables
Polling at intervals to see what tasks can be opened up based on row statuses
Individual row (s) can move forward (task for it can open up) when its status is ready for next step
Instance ID and one or two of the parameter values only as input to any task
Each task uses this context keys to read data from tables, all decisions updated immediately updated into columns of the tables.
WebApp or Process? Polled One Instance Design

Disadvantages:
BPD diagram does not show any “process”, just parallel boxes after a polling service
DB intensive, since polling load will increase over time
Need weighted polling, recent instances poll more frequently, older instances less frequently
Need to have some logic in BPD to terminate/stop polling after certain criteria is met for business data in tables

Advantages of this approach:
If business requirements change as to when to open a task, only change is in the polling query.
Incoming data issues can be fixed in tables from back end and its related task will open in next polling.
Complicated reporting easily possible by pure queries to the underlying tables, no performance server/ tracking
No issue of in-flight process upgrade
TeamWorks for Office plug-in used to alert the users of tasks for them instead of them actively logging into a web application.
If an instance fails beyond recovery, easy to open a new instance ID with same data without losing process input and putting it in exactly same state where it failed
