Disclaimer:
These solutions are based on my experience and best effort. Actual results may vary depending on your setup. Codes may need some tweaking.

1. What would you do if your Blue Prism bot failed in production during a high-volume transaction window?

First, I’d check the exception logs in Control Room to see where it broke and why.
I’d validate if it’s a business exception or system-level failure.
If it’s a business rule breach, I’d reprocess later with corrected input.
For system errors, I’d engage IT for infrastructure or credentials issues.
Meanwhile, I’d manually handle pending critical items if SLAs are at risk.
I’d also raise an incident for audit and ensure a root cause analysis follows.
This approach ensures minimal business impact and proper documentation.

2. How do you decide when to use multiple Blue Prism processes versus one consolidated process?

If the business logic is modular and reusable, I break it into smaller processes.
For example, login, data extraction, and report sending can be separate.
This promotes reuse, easier debugging, and faster changes later.
But if the process is small and tightly bound, one consolidated flow is fine.
I always look at maintainability, reusability, and the ease of testing.
Large monoliths are hard to update, while too many small processes add complexity.
Balance is key—modular but not fragmented.

3. What’s one common mistake developers make with Blue Prism object design?

Overloading one object with too many actions is a big mistake.
It makes testing, debugging, and future enhancements difficult.
Ideally, one object should target a specific application or purpose.
Actions should be focused and named clearly to reflect intent.
Another mistake is not separating business logic from object layers.
That kills reusability and makes the design fragile.
Clean, layered logic makes a huge difference in long-term maintenance.

4. What do you do if the Blue Prism process completes successfully but produces incorrect output?

I don’t rely only on success flags—I always verify output data.
First, I’d check if input values were mapped or read incorrectly.
Next, I’d review object stages, especially where data is captured or transformed.
A bad calculation or a UI element not returning correct data can be the cause.
Logging is critical here—I ensure detailed logs at each decision point.
I’d also simulate the process in dev to reproduce and isolate the issue.
Lastly, fix and deploy with strict QA so it doesn’t happen again.

5. When should you recommend not automating a process in Blue Prism?

If the process is highly manual but frequently changing, it’s a red flag.
Blue Prism works best on stable, rules-driven processes.
If there’s unclear ownership or missing documentation, I’d avoid it.
Also, if effort outweighs ROI—for example, a 5-minute task done once a month.
Processes involving high cognitive judgment or approvals need human touch.
I always run a proper PDD-FDD review before giving the go-ahead.

6. How do you handle credential failures in production bots securely?

Credentials are always stored in Blue Prism Credential Manager, not hardcoded.
If a bot fails due to credential change, I check expiry or locking issues.
Only credential admins are allowed to update it—not developers.
We rotate credentials regularly and follow least privilege access.
Monitoring alerts help identify failures quickly before they pile up.
I also ensure bots retry once or twice with controlled delay to avoid lockouts.

7. In your view, what’s the biggest business benefit of adopting Blue Prism?

The biggest value is scalable, rules-driven automation without user fatigue.
It frees up staff from repetitive tasks so they focus on analysis or service.
Blue Prism integrates well with existing apps without major infra changes.
It also supports audit trails, so compliance and governance are built-in.
Long-term, it reduces error rates and boosts processing speed.
It’s a great way to digitize legacy operations gradually.

8. Can you explain a trade-off you made in a real Blue Prism project design?

In one case, we had to choose between speed and stability.
Fast mode scraping was crashing the app intermittently.
We switched to region mode—slower but much more reliable.
Business preferred accuracy over speed in that process.
We documented the trade-off with performance metrics for sign-off.
Sometimes, success is about balancing risk, not perfection.

9. What limitations have you experienced with Blue Prism in complex use cases?

It struggles with dynamic web apps that reload frequently or use virtual DOM.
UI element recognition sometimes fails unless you use UIA or surface automation.
There’s no built-in AI/ML—needs integration with external tools for that.
Debugging live sessions is harder than attended automation tools.
Also, license cost and scalability need early planning.
It’s great for back-office but not ideal for real-time decision-heavy flows.

10. What lessons have you learned the hard way when working with Blue Prism in enterprise environments?

Never skip exception handling or logging—even in POCs.
Always plan for credential access and version control from day one.
Don’t assume every environment (Dev/UAT/Prod) behaves the same.
Involve business SMEs early to avoid surprises in test data.
Avoid over-customizing objects—you’ll regret it during maintenance.
Lastly, change management is critical—every small update must go through review.

11. What would you do if business stakeholders demand a process change mid-development?

First, I’d assess how critical the change is—regulatory, business priority, or cosmetic.
I never change logic without proper change request and impact analysis.
I’d involve BA to update the PDD and validate with dev team.
If timelines are tight, we may proceed with parallel build branches.
But I never compromise on testing—even for urgent changes.
Post-deployment, I’d document versioning and lessons learned clearly.

12. How do you handle process scaling when transaction volume suddenly spikes?

I always design processes with concurrency in mind—multiple bots if needed.
Control Room scheduling helps split queues across bots effectively.
We use work queues with proper priorities and tags for scaling.
Exception handling is designed to avoid queue lock or dead-bots.
I also monitor bot resource usage during scale tests to avoid crashes.
Scaling is not just adding bots—it’s smart load balancing.

13. What’s your strategy to reduce bot maintenance overhead in Blue Prism projects?

I keep business rules in separate stages so updates are easier.
Every object is modular and built for reuse across processes.
Naming conventions and logs are standardized from day one.
I use template processes for common functions like login, audit, etc.
Regular peer reviews catch hardcoded values or poor design.
Most maintenance issues are preventable with good planning.

14. Have you ever handled a failed Blue Prism deployment? What went wrong?

Yes, once a deployment failed because the production app URL changed.
The dev team didn’t sync with infra on that change during UAT.
The bot kept running but captured wrong data silently.
We paused the bot, corrected the object, and added dynamic URL logic.
After that, we introduced mandatory release checklists and endpoint alerts.
That incident taught us the cost of missing one small assumption.

15. When would you say a Blue Prism automation is truly “ready for production”?

Only after it passes all QA test cases, including negative paths.
Logs, retries, and exception flows must be validated.
Credentials must be live and secure in Credential Manager.
We do dry runs in production-like data, not dummy test sets.
Also, monitoring, SLA alerts, and business sign-off must be in place.
“Ready” means business impact tested—not just technically working.

16. How do you decide between Blue Prism and attended automation tools like UiPath?

Blue Prism is better when the use case is backend, rule-driven, and large scale.
Attended bots suit real-time, front-office, or agent-assist scenarios.
If the user must interact or make decisions, Blue Prism isn’t ideal.
For 24×7 processing and strong audit trail, Blue Prism leads.
Cost, skillset, and existing infra also play a role in decision-making.
I don’t compare tools blindly—it’s use-case and context-driven.

17. What are the risks if exception handling is skipped in Blue Prism?

Without it, the bot will crash on the first unexpected input or screen.
Errors may silently go unnoticed—especially if logs are also missing.
SLA failures can pile up and cause business disruptions.
You lose audit traceability, which is critical for compliance.
Fixing such bots later is painful and often leads to rewriting.
Exception handling is not optional—it’s core design hygiene.

18. What’s one thing you wish every new Blue Prism developer knew before starting?

Always test objects separately before calling them in processes.
Many beginners skip object testing and spend hours debugging.
Also, understand the difference between recoverable and unrecoverable exceptions.
Learn to use breakpoints and watch windows effectively.
Don’t rely on others’ code—understand the “why” behind each design.
These small habits separate good developers from average ones.

19. Can you share a process improvement idea you applied using Blue Prism?

One client was manually validating invoices against an Excel sheet.
We automated that by pulling invoice data from email and matching it using logic.
Added automatic status tagging and escalations for mismatches.
This reduced validation time by over 80% in the first month.
We later added a reporting bot for weekly summaries.
It started small but scaled beautifully with quick ROI.

20. What’s your approach when dealing with bots that fail only in Production but work in Dev and UAT?

I first check for environment-specific settings like resolution or security prompts.
Many times, Prod apps have different timeouts, popups, or URLs.
Credential mismatch or infra changes are also common causes.
I compare logs and screenshots across environments to find clues.
Adding dynamic waits or safe element checks often helps.
Consistency across environments is rare—my designs always account for that.

21. How do you handle Blue Prism processes that require accessing multiple applications at once?

I assign one object per application to keep things modular and clean.
Each app has its own login, error handling, and logic blocks.
I use global data items or session variables to pass data between objects.
Process flow is sequenced smartly so app dependencies don’t overlap.
Also, I avoid opening all apps at once to reduce memory load.
Testing cross-app flows is critical, especially for timing or credential issues.

22. What happens if a bot doesn’t release a resource properly after completion?

The session remains locked in Control Room, and new sessions can’t start.
That bot appears “active” but is doing nothing—leads to SLA breaches.
I use proper “End” stages and graceful exits to release resources.
Alerts or dashboards help us monitor idle or stuck sessions.
Sometimes, memory leaks or missed exception paths cause this.
Cleaning up resources is as important as executing logic.

23. How do you deal with a situation where Blue Prism bots are blamed for delays but logs show no failure?

First, I look at queue items—were they processed on time or stuck?
Just because there’s no error doesn’t mean performance was fine.
I check time logs between each stage to find slow points.
Business might expect faster results than what was agreed in SLA.
Clear communication and dashboards showing actual processing time help.
Data beats assumptions—logs speak louder than blame.

24. What trade-offs have you faced when choosing between image-based automation and proper element spying?

Image-based automation is easier but highly fragile to UI changes.
Spied elements are stable but sometimes don’t work with legacy apps.
I usually try spying first, then fallback to image methods with caution.
The trade-off is always between speed of development and long-term reliability.
We document where image-based methods are used and why.
It’s a design debt that must be revisited periodically.

25. What’s your approach to managing Blue Prism licenses across multiple teams?

We allocate licenses based on team priorities and process criticality.
Control Room scheduling ensures no idle licenses during business hours.
I use dashboards to track license usage trends monthly.
For seasonal spikes, we request temporary boosts with vendor coordination.
Also, license usage is part of every quarterly performance review.
Unused bots mean wasted budget—optimization is continuous.

26. What are the key things you validate during a Blue Prism peer code review?

Naming standards, retry logic, and clean exception handling.
No hardcoded values—everything should be parameterized or global.
Logs must be meaningful, not just status messages.
Avoid too many nested decisions—makes logic hard to follow.
Reusability and documentation are also big focus areas.
It’s not just code review—it’s about future-proofing the process.

27. What risks do you face when bots rely too much on hardcoded values or screen coordinates?

Even a slight UI layout change can break the bot instantly.
Hardcoded values reduce flexibility and increase support time.
It’s harder to scale or reuse such bots in other environments.
Maintenance becomes costly when every small change needs a redeploy.
I always externalize values into data items or config sheets.
A bot should be flexible—not fixed like a screenshot.

28. How do you ensure your bots are audit-compliant and traceable?

Every transaction is logged with unique ID, timestamp, and outcome.
Error logs are detailed, with screen values where possible.
We use secure Credential Manager for access logs and expiry tracking.
Every process has a change log and version history in documentation.
We follow naming conventions that link bots to business processes clearly.
Auditors love clarity—so I build it into the design.

29. What’s the business impact if queue prioritization is not set properly in Blue Prism?

High-priority items might get delayed or missed entirely.
SLAs may be breached even if bots are running 24×7.
Business teams lose trust when critical cases are not processed first.
I always tag and sort queue items by urgency or deadlines.
Control Room scheduling is synced with business calendars.
Priority is not just a field—it’s a commitment to business goals.

30. Have you ever had to rollback a bot deployment? What caused it?

Yes, once after go-live, the bot started creating duplicate records.
A logic flaw wasn’t caught in UAT due to missing test data.
We immediately rolled back to the previous stable version.
Then fixed the logic, added better validations, and updated test cases.
Rollbacks are painful, but they happen—it’s why version control matters.
Every deployment needs rollback planning as a safety net.

31. What would you do if business stakeholders are unsure which processes to automate first with Blue Prism?

I guide them using a scoring model—volume, rules-based, stability, and ROI.
Processes with repetitive tasks, fewer exceptions, and high volume rank higher.
I conduct quick workshops to walk through candidate processes.
We avoid anything that changes weekly or needs deep human judgment.
Also, I bring in SMEs early so there’s no misalignment later.
Choosing the wrong process can kill automation trust early on.

32. How do you keep business users confident about Blue Prism bot performance post go-live?

I give them live dashboards that show bot progress and statuses.
Exception reports are scheduled and shared regularly.
For the first few weeks, I hold daily syncs to review outcomes.
Transparency builds trust—no black box behavior.
I also share savings metrics to show actual value delivered.
When they see value, support for RPA grows fast.

33. What’s your strategy when a Blue Prism bot starts slowing down after a few weeks of running fine?

I check memory and CPU usage—bot servers may be under strain.
App updates or patching may have impacted UI loading times.
I review logs to identify new delays or timeouts.
Sometimes queue size or retry loops cause slowdowns.
I always keep performance baselines to compare against.
Bots age too—monitoring keeps them healthy.

34. How do you ensure Blue Prism bots adapt to changing business rules over time?

I externalize business rules into config sheets or global values.
So if rules change, we only update configs—not the code.
Frequent changes are flagged early during PDD review.
Every rule is clearly documented with ownership.
Change control is strict—every update gets tested.
Flexibility is built by design, not as an afterthought.

35. What’s the most overlooked factor when planning a Blue Prism bot for a critical business function?

People forget about exception volume and manual fallback plans.
Bots fail too, so a backup workflow must exist.
Also, access dependencies—if one app login fails, the whole flow halts.
Notification setup is often ignored until it’s too late.
Finally, time zones and calendar logic are critical for global processes.
Missed these once—you’ll never forget them again.

36. Have you ever reused a Blue Prism object in a way that saved a project timeline?

Yes, we reused a login object built months earlier for another app.
It had dynamic credentials and retry logic already tested.
Saved at least 3 days of development and retesting.
We also reused Excel-related VBOs in multiple reporting flows.
Object reuse is a habit—build it once, use it wisely.
That’s how mature automation scales fast.

37. How do you handle a Blue Prism queue with thousands of items and a tight deadline?

I prioritize items using tags and sort orders.
Multiple bots are assigned in parallel with time-sliced schedules.
Retry logic is minimal—just one retry before moving to exception.
I break queues into batches if needed to reduce load.
Alerts are configured to catch stuck or slow sessions.
It’s not just volume—it’s smart execution that beats the clock.

38. What’s your way of handling a stakeholder who demands real-time automation but the process isn’t suitable?

I walk them through the process complexity and response-time limits.
Blue Prism isn’t real-time—it’s best for back-office or batch tasks.
I offer alternate solutions like APIs or attended bots where needed.
If they insist, we prototype and show the limitations clearly.
Education works better than resistance in such cases.
Aligning expectations is half the job.

39. What are some key process risks you document before a Blue Prism bot goes live?

Failure points like app crashes, slow UI, or missing credentials.
Business logic assumptions—what we expect from data or fields.
SLA impact if bot halts or delays.
User access issues or lockouts.
Exception handling coverage and fallback readiness.
Every risk has an owner and mitigation plan.

40. How do you track the value delivered by a Blue Prism bot to business?

I use baseline metrics: manual effort, errors, and time taken before bot.
Post-deployment, we measure time saved and error reductions.
I also track how many queue items are handled daily.
Reports include rework avoided and SLA compliance trends.
Savings are shown in hours, dollars, and FTE reduction if possible.
Value is not just running bots—it’s proving impact.

41. What’s your approach when a business SME provides unclear or conflicting requirements during automation design?

I start by documenting everything in a PDD draft—no assumptions.
Then I schedule workshops with the SME and BA to clarify each flow.
Visual diagrams help uncover gaps and resolve conflicts.
I highlight automation blockers early so there’s no scope creep later.
Every update is versioned and tracked with sign-offs.
Clear inputs make better bots—confusion leads to rework.

42. How do you manage Blue Prism bot handovers to support teams post-deployment?

I provide a detailed runbook with steps, exceptions, credentials, and recovery.
Support teams get training sessions with live bot walk-throughs.
We include escalation paths and SLA windows in the document.
Logs, alert settings, and dashboards are also explained.
Support needs context—not just a ZIP file.
Good handovers prevent panic tickets and finger-pointing later.

43. What are some signs that a Blue Prism bot has poor design quality?

Too many retries, unclear log messages, or hardcoded values.
Long, unreadable processes without modular design.
Lack of proper exception handling or recovery stages.
Over-reliance on exact screen positions instead of element spying.
Objects doing too much—violates separation of concerns.
Clean bots are lean, readable, and predictable.

44. What would you do if your Blue Prism bot starts failing randomly with no pattern?

I increase logging granularity to capture more details.
I check for intermittent popups, network latency, or app timeouts.
Windows updates or background processes might be interfering.
Run the bot manually step-by-step to isolate the issue.
If needed, I simulate load or run it on another VM.
Random failures usually point to environmental or timing issues.

45. How do you ensure Blue Prism bots don’t break after application UI upgrades?

I schedule coordination with app owners before major UI releases.
Use dynamic attributes when spying elements—not static IDs.
Keep objects modular so only the affected ones need edits.
Run regression testing after UI updates using test queues.
Document all UI dependencies clearly in PDD/FDD.
UI upgrades are inevitable—prepare, don’t panic.

46. What are the pros and cons of using Blue Prism for data-heavy processes like reports or file handling?

Pros: Great at handling repetitive file tasks, Excel automation, and logs.
Cons: Performance drops if files are too large or need real-time sync.
I often use small batches to avoid memory overload.
Bots don’t replace ETL tools—they complement them.
For heavy lifting, integration with scripts or APIs works better.
Know the limits—Blue Prism isn’t a data warehouse.

47. How do you avoid over-automation or automating bad processes with Blue Prism?

I assess each candidate process using a scorecard: volume, complexity, and frequency.
Low-value or unstable processes are filtered out early.
Just because something can be automated doesn’t mean it should.
I always ask: is the process itself optimized before we touch it?
Automating waste only increases tech debt.
Start smart, not just fast.

48. Have you ever seen business rules misunderstood during automation, and what was the impact?

Yes, once a date-format logic was misunderstood by the dev team.
The bot sent reports with wrong aging buckets for a week.
Business caught it during reconciliation, and we had to halt the bot.
After that, we made business rule review mandatory before build.
Even one misunderstood rule can undo trust in automation.
Validation is not just for dev—it starts at understanding.

49. What are the signs that your Blue Prism process needs a redesign instead of a patch?

Too many exceptions or frequent hotfixes post-go-live.
Business keeps raising change requests monthly.
Logic becomes unreadable or too nested to follow.
Any change breaks something else—shows brittle design.
Stakeholders are frustrated despite the bot “working.”
Sometimes it’s cheaper to rebuild than to keep patching.

50. How do you make sure Blue Prism automation aligns with larger digital transformation goals of a company?

I tie every bot’s outcome to business KPIs like time saved or revenue impact.
Regular reviews align RPA roadmap with business OKRs.
I work with IT and Ops to integrate bots with analytics and reporting.
Automation is part of a bigger puzzle—not the whole picture.
Bots should serve strategy, not just tasks.
That’s how you go from RPA pilot to enterprise value.

51. How do you handle stakeholders pushing for faster bot delivery without proper testing time?

I explain the risk using examples of past failures due to rushed UAT.
Share clear impact: failed go-live, data errors, and production outages.
I negotiate phased delivery: critical items first, rest in wave 2.
Use actual effort estimation to justify timelines.
Cutting testing always costs more later—stakeholders usually agree.
Good delivery isn’t just speed—it’s stability too.

52. Have you ever built a bot that was later retired? What led to that decision?

Yes, a data reconciliation bot was retired after the company switched ERPs.
The process itself became obsolete as systems integrated directly.
Instead of fixing it, we decommissioned with stakeholder approval.
We ensured documentation and history logs were stored safely.
Bots don’t last forever—some are stepping stones in transformation.
Retirement is part of the automation lifecycle.

53. What are the biggest technical risks in Blue Prism deployments that go across multiple regions?

Different time zones can mess with scheduling if not planned right.
Language and currency formats may affect data parsing.
Infrastructure varies—some VMs lag or timeout more.
Local holidays or SLAs must be handled per region.
Even credential policies differ—adds overhead.
Always plan regionally but think globally.

54. What’s your view on balancing business logic in Process layer vs Object layer in Blue Prism?

Business rules belong in Process—objects just interact with apps.
Keeping logic in objects leads to duplication and confusion.
Objects should be reusable across many processes.
When rules change, only Process should need updates.
Clean separation saves time during enhancements or audits.
It’s architecture 101—follow it or pay later.

55. What are some common security pitfalls when automating with Blue Prism?

Hardcoding credentials or using shared logins is a major risk.
Storing sensitive data in logs without masking.
Not limiting access roles—too many devs with admin rights.
Forgetting to rotate passwords or manage expired credentials.
Skipping audit trails or access logs.
Bots must follow the same security standards as humans.

56. How do you handle Blue Prism upgrades in a large enterprise setup?

First, I clone production setup in lower environment for dry-run testing.
All processes and objects are tested against the new version.
We use a freeze window and inform all business teams.
Upgrade is scheduled outside business hours with rollback plan ready.
Post-upgrade, full regression testing is mandatory.
No upgrade is minor in production—always plan for surprises.

57. What’s one lesson you learned from a failed automation that stuck with you?

Once, we automated a process with hidden manual approvals not documented.
Bot kept stalling but didn’t throw errors—caused business delays.
I learned that “walk the process” with SMEs beats any documentation.
Always dig deeper during PDD phase.
Hidden steps are the real automation killers.
Now, I never trust surface-level process maps.

58. How do you align Blue Prism automation with long-term IT strategy in the company?

I engage with enterprise architects and IT planners early.
Automation roadmap is synced with app upgrades and infra changes.
I push for reusability, version control, and platform governance.
Bots aren’t one-off—they’re part of digital delivery pipelines.
Strategic alignment prevents rework and scales better.
Bots that align with IT strategy don’t get retired—they grow.

59. Have you ever had to justify Blue Prism ROI to executives? How did you do it?

Yes, I presented before-after metrics: hours saved, errors reduced, SLA gains.
Used dashboards and heatmaps to show automation footprint.
Tied each bot to a business value—cost savings or customer satisfaction.
Shared success stories from teams using the bots daily.
ROI isn’t just money—it’s trust, time, and scale.
Data-backed storytelling wins every time.

60. What’s your personal checklist before marking any Blue Prism bot “ready for go-live”?

Logs tested, exception paths covered, retries configured properly.
Credentials stored securely and test data cleared.
Queue volume tested with production-like load.
Business sign-off obtained with UAT evidence.
Monitoring alerts set and support team onboarded.
If any item is red, it’s not ready—checklists never lie.
