2. • Identifying the process
• Choose right project team; Project Manager, Solution
Architect, Business Analyst, Developer and Tester.
• Create Effort Estimation Document for Technical Team
• Capture Process Steps and Implement in Documents
(Process Design Document).
• Develop Test Cases
• Testing with Process Owner

Establishing what is in and out
of the scope for RPA
Taking part in the “As is”
process walkthroughs
Setting the “To be” process up
along with the BA
When the “To be” is designed, the RPA SA
already establishes the architecture: Input data,
Output data, Sub-Processes, Integration,
Scheduling

Development Effort Estimation - Guidelines
Effort estimation needs to be conducted in the analysis phase
The RPA SA should thoroughly understand the process and
collaborate with the BA and PM
High-level process breakdown requires individual estimation
The SA should identify the potential challenges
Preliminary integration should be tested - applications and
particular screens with UiPath Studio
The SA should process a few transactions manually and they
should try selectors in UI Explorer and evaluate if they will
pose difficulties during the development.
The complexity of the applications and business rules should
be taken into account when handling exceptions
The level of your RPA developers should be considered
Studio workflow creation, Orchestrator configurations, and
dashboards should be included
Unit and functional testing should be considered
Additional change requests after the PDD sign off need to be
documented, approved by the Process Owner and more time
needs to be added on top of the original effort estimation
Diminishing returns when multiple developers work on the
same process
RPA Projects are difficult to estimate, as many challenges
arise during development. Additional time should be
considered – typically 30% or more

Sub Process Components Estimation
Dispatcher Combine data from Emails,
Add to Queue
2 days
Performer Initialize 1 day
Performer Navigation and Extraction 1 day
Performer Adding New Suppliers 1 day
Performer Deleting and merging
duplicate Records
3 days
Dispatcher/Performer Integration, Functional
Tests
4 days
Total Estimation All + 30 % 16 days
Example for Dev Effort Estimation
Number of sub-processes : 2 ( Dispatcher and Performer)
Number of applications used : 3 (Outlook, Demo App, Excel)
Process complexity – Medium ( Queue process, More rules)
Some difficulty in getting data structured from Email and Application
Feasibility testing successful for Demo App
Need more error handling in Performer based on PDD

As Is and To
Be Diagrams
The process logic is
reflected clearly in the
diagrams. Behavior for
known exceptions is
present
Each sub-process has
its own diagram.
In the case of large
processes, there’s a
high-level diagram
giving an overview of the
processes
Step by step

There is no ambiguity
regarding input data
sources
UI steps thoroughly
documented (i.e. a
person can understand
the process solely based
on this document)
Any rule-based logic
applied at a certain step
will be extensively
documented with
examples
Exception
Handling
Behavior defined for
both expected and
unexpected exceptions
Input data exceptions
are documented,
especially in the case of
unstructured data
Screenshots present for
known application
exceptions
Input / Output
Templates for the output
files and emails that the
robot will have to send
Input Data samples are
added to the PDD
No undocumented input

• General tips for designing optimal test case
Test Cases Guidelines
Simple and Specific – each test case should clearly cover a test scenario in as few
words as possible
Clearly defined input and expected results
Each testcase should be non-redundant with other testcases
The testcases should cover all possible scenarios, including Application Exceptions,
Business Exceptions and all cases of Successful Transactions
Defined in such a way that the isolation and identification of bugs is facilitated
