RPA Use Cases – Data Migration & Management

Robotic Process Automation helps in manage data in efficiently and accurately.

Data Migration & Management Overview

Big data is getting bigger. More and more data is being generated from
multiple sources and it’s getting tougher and more and more time
to consume to manage, measure and analyze. And with this increasing
amount of data available, manual processes and human intervention leave
a greater margin of error.

Many businesses today collate data from multiple sources, such as web
pages for online orders, invoice workflow, email exchanges and Excel
spreadsheets, effectively requiring individuals to log in and out of multiple systems, copying and pasting data between different sources and formats.

Implementing RPA to automate this high-volume, low complexity tasks cannot only ensure optimal resource utilization but also improve employee productivity.

By replicating human data entry, RPA can be deployed to transfer, manipulate and migrate application and system data quickly, reliably and with a full audit trail, thus avoiding manual re-keying and re-entry and vastly reducing the high instances of human error.

By removing this the margin for error, the data becomes 100% accurate, so the insights and subsequent business decisions are more likely to succeed.

Deploying RPA can also enhance customer and supplier system integration as it provides an electronic interface to the customer and/or supplier systems where a system to system, interface is challenging or not possible.

Robotic Process Automation Case Study

Sector: Business Process Services

Challenge – This IT and Business Process outsourcer was providing a  management service for one of its customers, recording all activities in its own case management application, a shared platform used across all of their clients.

However, this specific customer required the information to be recorded in its own dedicated system too. Using the client’s case management application as well as their own was simply inefficient. However, the two systems could not be connected due to client restrictions, so the only way to get case information from the client system to the service provider system and vice-versa was to use people.

By recruiting temporary staff and redeploying staff from other duties, 12 employees were assigned to manually rekeying the records from one system to the other. This slow process was creating a huge backlog of cases to be migrated and updated.

Robotic Process Automation Case Study Outcome

An automated solution was deployed with Virtual Workers replicating the data from one system to the other, replacing the 12 staff with just two Virtual Workers and delivering work out of hours to minimise the overall customer impact. The backlog of cases was quickly cleared and the reduced cost of temporary staff saved the client around £200K in the first three months of operation.

RPA Real World Use Cases – IT And Infrastructure Support

Robotic Process Automation Case Study and RPA Use Cases. RPA in IT & Infrastructure Support. How your company can improve efficiency and faster time to deployment with the help of Robotic Process Automation (RPA).

RPA Use Cases – IT & Infrastructure Support

Robotic Process Automation helps in faster time to deployment in Information Technology and Infrastructure support.

IT & Infrastructure Industry Overview

IT support staff are highly skilled, well trained and valuable resources.
But many businesses see their IT Support team spending too much time
manually undertaking systems administration tasks, running diagnostics
and system checks, managing patch processes, backups and many other
daily tasks and just do not have the time or the budget to increase head
count to handle more high value, skilled tasks, or work on business improvement and change projects.

You Should Read This: Introduction to Robotic Process Automation

Companies can optimise their IT resources with the support of a Virtual Workforce. Through either assisted-automation (automation with human support either to initiate or approve actions), or by fully automating (no human intervention) existing user actions and taking over labor-intensive administrative tasks, employees are freed up for more intellectually demanding activities. By focusing on subjective decision-making, innovation and customer-facing activity that can’t be automated, the IT team is far more efficiently employed and feel more professionally engaged.

This Virtual Workforce is, of course, available 24/7. They don’t make mistakes. They don’t deviate from the defined process. They never have a bad day. They work at machine speeds. And at busy times, in an instant more of them can be called upon to step in and take up the load.

Related Article For You: Know The Reality of Robotic Process Automation

They are simple to deploy – often in areas where automation was previously considered to be unviable, and they are easy to manage with a significantly lower level of investment. And above all, you can rest assured that the jobs are getting done – on time, consistently and accurately.

Robotic Process Automation Case Study

Sector: Information Technology

Challenge – A market leading managed service provider was faced with the
challenge of a new client needing a niche skilled support solution for its systems and applications. The complex management requirements for the new client’s systems left the IT provider with the prospect of having to employ expensive experts to run a 24/7 service operation.

Robotic Process Automation Case Study Outcome

Virtual Workers were deployed to manage and automate the various complex, low volume system administration tasks around IT applications and infrastructure, including validation, regular testing, diagnostics and fault remediation.

This replaced the need to recruit further highly trained staff to perform these tasks. The quality of the service delivered by the provider has improved vastly, with previously time consuming, yet critical activities now being executed more regularly, ultimately offering speedy system support.

The solution not only delivered a better service, but also produced an estimated saving of £250K in staff costs compared to the use of offshore resources, or £500K compared to locally employed staff.

RPA Real World Use Cases – Customer Service And Support

Robotic Process Automation Case Study and RPA Use Cases. How your business can improve efficiency and customer satisfaction with the help of Robotic Process Automation (RPA).

RPA Use Cases – Customer Service & Support Desk

Robotic Process Automation can improve efficiency and customer satisfaction

Customer Service & Support Desk Industry Overview

Typically, call centers and service desks use a number of different systems
and applications and often undertake a high volume of low complexity
repetitive tasks.

When someone calls in, service agents have to navigate these applications while at the same time managing their interaction on the call with the customer. If users connect via email or messaging systems, agents need to translate information from those systems while executing the required actions.

But having to jump back and forth between systems and screens shifts is slow and inaccurate. In a live call, the focus moves away from the caller and the perception of the customer is impacted.

You Might Interested In: Robotic Process Automation Reality

Disparate systems may require the same information – who hasn’t experienced being asked the same identity verification questions multiple times by the same call center?

Additionally, post-call follow up, such as updating records and recording closure activity can take almost as much time as the call itself, thus negatively impacting upon agent productivity.

A good customer experience can drive long-term growth. Which is why customer satisfaction should be the ultimate goal of service desk and call center performance.

Customer Service Automation With RPA

RPA can be used to automate many of the common tasks in a customer service or support desks, such as incident management, billing queries, user administration and updating records, to deliver many benefits.

Not only can it ensure tasks run flawlessly and consistently during waking and sleeping hours and address and resolve problems on its own, it can link
disparate systems and applications in one single console, build a unified knowledge base that delivers relevant data in real time, and automatically set up and run processes.

You Might Interested in: RPA Interview Questions

Agents are freed from having to process repetitive, manual tasks and can focus on developing their customer-centric skills. And don’t forget, Virtual Workers can be many times faster than a person.

This allows for a faster turnaround for customer requests and significantly improves SLAs.

Robotic Process Automation Case Study

Sector: Managed Services

Challenge – A leading European IT Managed Service provider was running a support service for a leading industrial customer who had a large number of employees and a broad mix of legacy and new applications. Handling over 15,000 calls a month, a significant amount of time was being spent by the 1st line support team executing user administration tasks.

In fact, due to the complexity of the systems and processes, the average time for each such incident was almost 6 minutes, as the agent had to inefficiently navigate various systems to access, manipulate and update information, subsequently offering an inefficient service and poor customer experience.

Robotic Process Automation Case Study Outcome

Delivered within 2 weeks, the automated solution – provided through Virtual Workers in place of human agents – was able to complete tasks in less than 50 seconds – that’s an 83% reduction in execution time.

Along with this improved customer service, the volume of support resource required has been significantly reduced and a number of support technicians have subsequently been redeployed, producing a tangible cost
efficiency saving of an estimated €1M.

  • RAPID DEPLOYMENT – 2 week project
  • EXECUTION TIME – Reduced by 83%
  • PRODUCTIVITY SAVING – > €1M annually

Robotic Process Automation From Thoughtonomy

Robotic Process Automation From Thoughtonomy. In this fast-paced, competitive and dynamic world, the need for speed is vital. Businesses want increased productivity with less resource, more cost savings, and improved accuracy, to offer the ultimate customer experience. Customers increasingly expect an on-demand service with an instant response and service – anywhere and anytime they want it.

Robotic Process Automation

Many of the limitations to meeting such immediate, round the clock customer expectations, relate to the people-centric way services are delivered. As such, there has been a surge of interest in robotics, Artificial Intelligence (AI) and process automation in recent years to address these
challenges.

Some commentators express concerns at the impact, including the World Economic Forum, whose 2016 Davos Report forecasts “Disruptive labor market changes, including the rise of robots and artificial intelligence, will result in a net loss of 5.1 million jobs over the next five years in 15 leading
countries.” However, Forrester takes a more balanced and realistic view, stating “advances in automation technologies will mean humans increasingly work side by side with robots, software agents, and other machines.”

Robotic Process Automation – The Line Between Hype And Reality

RPA Disruptive Technology

In fact, with the global pace of change, organizations that continue to rely on manual processing will lose their competitive edge. As process automation enables large volumes of tasks to be achieved quickly and
accurately, and in turn, reduces costs and improves efficiencies, Robotic Process Automation provides the foundation for significant competitive advantage.

It’s clear that Robotic Process Automation has the potential to add substantial value and improve customer outcomes – and the concept
of Virtual Workers operating as part of a blended human and machine workforce is here to stay.

What is Robotic Process Automation?

Today, across the world, many millions of hours of staff in customer services, business support and operations are being consumed with mundane, manual, labor-intensive activities. While much of the headline-grabbing may come from the concept of Artificial Intelligence and
self-learning systems, the fact is that if these mundane tasks were automated, the benefits would be huge, with staff freed up to focus on higher value activities, improved speed, and accuracy and significantly reduced costs.

Advanced RPA Interview Questions For Experienced

Introducing Robotic Process Automation

Robotic Process Automation (RPA) is the application of automation software to carry out tasks and activities in applications and systems
by interacting with them in the same way as a human. “Virtual Workers” replicate the specific actions a human would take while working
with IT systems, the decisions they make, and the logical processes
they follow. This might include interacting with an in-house
application, website, user portal, email, Microsoft Office suite and more.

Furthermore, virtual workers work 24/7 at the machine – not human – speeds. They are technology-agnostic, can use any system or device with a graphical or command line interface and can carry out any data-driven,
rule-based process. As they are using (rather than replacing) an organization’s existing technology, they are both completely complementary to core systems and entirely non-disruptive for day-to-day business.

Blue Prism Interview Questions And Answers

RPA Capability

This makes RPA a capability that can be leveraged irrespective of industry and application, delivering ROI often within 3 to 6 months. RPA is fast emerging as a disruptive technology solution capable of delivering
multiple benefits. It is already having an impact at organizations currently deploying virtual workforces.

In the next few years, RPA will become an essential tool for more and more businesses looking to reduce costs, enhance accuracy, increase scalability, boost productivity and increase compliance. The benefits are simply too significant to be ignored.

Jenkins Advanced Interview Questions # 23) How do you create a Job in Jenkins?

Answer # Go to Jenkins top page, select “New Job”, then choose “Build a free-style software project”. This job type consists of the following elements:

optional SCM, such as CVS or Subversion where your source code resides.
optional triggers to control when Jenkins will perform builds.

some sort of build script that performs the build (ant, maven, shell script, batch file, etc.) where the real work happens optional steps to collect information out of the build, such as archiving the artifacts and/or recording javadoc and test results.

optional steps to notify other people/systems with the build result, such as sending e-mails, IMs, updating issue tracker, etc.

 

Selenium Jenkins Interview Questions # 24) How do you configuring automatic builds in Jenkins?

Answer # Builds in Jenkins can be triggered periodically (on a schedule, specified in configuration), or when source changes in the project have been detected, or they can be automatically triggered by requesting the URL:

http://YOURHOST/jenkins/job/PROJECTNAME/build

 

Jenkins CI Interview Questions And Answers # 25) How to create a backup and copy files in Jenkins?

Answer # To create a backup, all you need to do is to periodically back up your JENKINS_HOME directory. This contains all of your build jobs configurations, your slave node configurations, and your build history. To create a back-up of your Jenkins setup, just copy this directory.

Jenkins Real-Time Interview Questions

26) What is the trustAnchors parameter must be non-empty error and how can you solve it?

A) This trustAnchors parameter must be non-empty error means that the truststore you specified was not found, or couldn’t be opened due to access permissions for example.

EJP basically answered the question (and I realize this has an accepted answer) but I just dealt with this edge-case gotcha and wanted to immortalize my solution. I had the InvalidAlgorithmParameterException error on a hosted jira server that I had previously set up for SSL-only access.

The issue was that I had set up my keystore in the PKCS#12 format, but my truststore was in the JKS format. In my case, I had edited my server.xml file to specify the keystoreType to PKCS, but did not specify the truststoreType, so it defaults to whatever the keystoreType is. Specifying the truststoreType explicitly as JKS solved it for me.

27) What are the feature differences between Jenkins and Hudson?

A) Jenkins is the recent fork by the core developers of Hudson. To understand why, you need to know the history of the project. It was originally open source and supported by Sun. Like much of what Sun did, it was fairly open, but there was a bit of benign neglect. The source, trackers, website, etc. were hosted by Sun on their relatively closed java.net platform.

Then Oracle bought Sun. For various reasons Oracle has not been shy about leveraging what it perceives as its assets. Those include some control over the logistic platform of Hudson, and particularly control over the Hudson name. Many users and contributors weren’t comfortable with that and decided to leave.

So it comes down to what Hudson vs Jenkins offers. Both Oracle’s Hudson and Jenkins have the code. Hudson has Oracle and Sonatype’s corporate support and the brand. Jenkins has most of the core developers, the community, and (so far) much more actual work.

In fact, arguably it was Oracle who did the forking! And technically, too, that’s kinda what happened.

It’s interesting to see what comes out of “Hudson” though. While the “Winston summarizes the state and rosy future of the Hudson project” stuff they posted on the (new) Hudson website originally seemed like odd humour to me, perhaps this was a purposeful takeover, and the Sonatype guys actually have some big ideas up their sleeve. This analysis, suggesting a deliberate strategy by Oracle/Sonatype to oust Kohsuke and crew to create a more “enterprisy” Hudson is a very interesting read!

In any case, this brief comparison a fortnight after the split—while not exactly scientific—shows Jenkins to be by far more active of the two projects.

Jenkins has continued the path well-trodden by the original Hudson with frequent releases including many minor updates.

Oracle seems to have largely delegated work on the future path for Hudson to the Sonatype team, who has performed some significant changes, especially with respect to Maven. They have jointly moved it to the Eclipse foundation.

I would suggest that if you like the sound of:

Less frequent releases but ones that are more heavily tested for backwards compatibility (more of an “enterprise-style” release cycle)

A product focused primarily on strong Maven and/or Nexus integration (i.e., you have no interest in Gradle and Artifactory etc)

Professional support offerings from Sonatype or maybe Oracle in preference to Cloudbees etc

You don’t mind having a smaller community of plugin developers etc.
, then I would suggest Hudson.

Conversely, if you prefer:

More frequent updates, even if they require a bit more frequent tweaking and are perhaps slightly riskier in terms of compatibility (more of a “latest and greatest” release cycle)

A system with more active community support for e.g., other build systems / artifact repositories

Support offerings from the original creator et al. and/or you have no interest in professional support (e.g., you’re happy as long as you can get a fix in next week’s “latest and greatest”)

A classical OSS-style witches’ brew of a development ecosystem

then I would suggest Jenkins.

Jenkins CI Interview Questions

28) How to trigger a build remotely from Jenkins? How to configure Git post commit hook?

The requirement is whenever changes are made in the Git repository for a particular project it will automatically start Jenkins build for that project.

A) As mentioned in “Polling must die: triggering Jenkins builds from a git hook”, you can notify Jenkins of a new commit:

With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>
This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)

This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.

As mentioned here, make sure to use the right address for your Jenkins server:

since we’re running Jenkins as standalone Webserver on port 8080 the URL should have been without the /jenkins, like this:

http://jenkins:8080/git/[email protected]:tools/common.git
To reinforce that last point, ptha adds in the comments:

It may be obvious, but I had issues with:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>.
The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our case ssh://, and it didn’t work.

You can also use a simple post-receive hook like in “Push based builds using Jenkins and GIT”

#!/bin/bash
/usr/bin/curl –user USERNAME:PASS -s \

http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx
Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (1qaz2wsx in this example).

However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn’t depend on authentication or a specific project.

I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.

Basically, your build script can:

put a ‘build’ notes (see git notes) on the first call
on the subsequent calls, grab the list of commits between HEAD of your branch candidate for build and the commit referenced by the git notes ‘build’ (git show refs/notes/build): git diff –name-only SHA_build HEAD.
your script can parse that list and decide if it needs to go on with the build.
in any case, create/move your git notes ‘build’ to HEAD.

Chef Interview Questions And Answers

1) What is chef in devops?

A) Chef is a configuration management tool for dealing with machine setup on physical servers, virtual machines and in the cloud.
Many companies use Chef software to control and manage their infrastructure including Facebook, Etsy, Cheezburger, and Indiegogo.

2) What is chef in automation?

A) Chef is a powerful automation platform that transforms infrastructure into code.s The Chef server acts as a hub for configuration data.
The Chef server stores cookbooks, the policies that are applied to nodes, and metadata that describes each registered node that is being managed by the chef-client.

3) What is chef DK?

A) The Chef DK workstation is the location where users interact with Chef. On the workstation users author and test cookbooks using tools such as Test Kitchen and interact with the Chef server using the knife and chef command line tools.

4) What are chef client nodes?

A) Chef client nodes are the machines that are managed by Chef. The Chef client is installed on each node and is used to configure the node to its desired state.

5) What is a chef server?

A) The Chef server acts as a hub for configuration data. The Chef server stores cookbooks, the policies that are applied to nodes, and metadata that describes each registered node that is being managed by Chef. Nodes use the Chef client to ask the Chef server for configuration details, such as recipes, templates, and file distributions.

6) What are work stations in chef?

A) A workstation is a computer running the Chef Development Kit (ChefDK) that is used to author cookbooks, interact with the Chef server, and interact with nodes.

The workstation is the location from which most users do most of their work, including:

Developing and testing cookbooks and recipes
Testing Chef code
Keeping the chef-repo synchronized with version source control
Configuring organizational policy, including defining roles and environments, and ensuring that critical data is stored in data bags
Interacting with nodes, as (or when) required, such as performing a bootstrap operation

7) What are Cookbooks in chef?

A) A cookbook is the fundamental unit of configuration and policy distribution. A cookbook defines a scenario and contains everything that is required to support that scenario:

Recipes that specify the resources to use and the order in which they are to be applied
Attribute values
File distributions
Templates
Extensions to Chef, such as custom resources and libraries

8) What is chef repo?

A) The chef-repo is a directory on your workstation that stores:

Cookbooks (including recipes, attributes, custom resources, libraries, and templates)
Roles
Data bags
Environments
The chef-repo directory should be synchronized with a version control system, such as git. All of the data in the chef-repo should be treated like source code.

9) What is chef-client Run?

A) A “chef-client run” is the term used to describe a series of steps that are taken by the chef-client when it is configuring a node.

10) What is chef validator?

A) chef-validator – Every request made by the chef-client to the Chef server must be an authenticated request using the Chef server API and a private key. When the chef-client makes a request to the Chef server, the chef-client authenticates each request using a private key located in /etc/chef/client.pem.
