The document discusses reducing average handle time (AHT) for a business credit services process at Genpact. The current AHT is 405 seconds, exceeding the target of 300 seconds set by the client, General Electric. Analysis found 46.61% of agents had AHT above the target. To improve AHT, the document defines a project charter to analyze causes of high AHT and identify improvements. Key metrics like AHT will be measured and potential factors like trainers, process knowledge, shift timing, gender and more will be analyzed to understand their impact on AHT. The goal is to improve AHT to the target of 300 seconds by November 30th without impacting quality.

How to improve call center quality and performance - InfographicPointel Inc
Improving call center quality and performance means looking at the way each employee handles calls. The employee must treat each customer with respect and take all the appropriate steps in order to ensure that the call is handled correctly. Poor quality can upset customers and reduce your profit.

There are bound to be times when your customer support team encounters a problem dealing with customers. You have no control over what customers say or do, but you do have control over how team members respond to questions or complaints in an efficient and productive way. With a combination of competent team members, well-written scripts and the right technology, your business can attract and retain happy and loyal customers.
Process maps (flowcharts) are one tool companies use to ensure team members know how to address customer support questions, escalate issues, and route calls. In this presentation, we begin with a process map given to employees working in a call center to screen job candidates. If you enjoy working with flowcharts, you’ll love this method to investigate your own customer service model. More process map templates are available for download at www.eqbsystems.com/shop.

Operating with clear processes makes or breaks organizational performance and it's an aspect of operations that is often fairly weak. Measuring organizational performance—whether overall performance or the performance of a small work team—is another area that we find often organizations struggling with.
In this webinar—the 3rd of 5 webinars based on content from my latest book, Clarity First—you'll learn the five criteria for robust process management and best practices for measuring and managing performance at any level in the organization. Additional topics will include creating and using standard work, how to properly roll out process changes, and avoiding measurement that drives the wrong behaviors.
This is an example of the 21 Call Center Best Practices that I and my staff designed, developed and deployed to Call Centers. These practices delivered increased focus on the customers, increased agent morale, improved productivity, increased revenue and reduced turn-over. Within this presentation I have only presented the marketing data but we developed procedures, and training materials to go along with all the Call Center Best Practices we deployed globally. See the attached presentation for how all the Best Practices fit together to drive Customer Delight. For additional information please feel to contact Brian Hughes.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. PROJECT CHARTER
Business case:
Genpact is the leading outsourcing firm with clients from across
the globe. GE HealthCare - Business Credit Service (GE-HC : BCS)
is one of the prominent client for Genpact for over 5 years.
GE-BCS caters to end customer’s queries, concerns and requests.
The process is unable to meet the AHT target for this quarter
resulting to customer dissatisfaction. If the same persist
consecutively for three quarters, the client might take away the
business. Hence, lies the opportunity to satisfy the customer and
increase company revenue.
Team:
Sponsor-Kunal Giri
MBB-Naresh Rao
Champion-Alka Shukla
Process owner-Gunjit Narang
BB-Jatin Sharma
GB-Jasjot Masuta

Problem Statement:
AHT of the process-BCS was 405 seconds resulting to miss
service-level in last quarter. 46.61% agents were below the target
AHT of 300 seconds.
This AHT target will improve the business delivery and eventually
enhance opportunity to earn more revenue to the company.
Client might pull back the business if the AHT target is
not met in the next quarter.
Goal Statement:
To improve AHT of the process to 300

Trainees under Sonia have better AHT at C6. Amit’s trainees have better AHT at C6 vs C5
Trainees in location L2 have lesser AHT vs trainees in L1 under trainer Amit
Trainees in location L1 have lesser AHT vs trainees in L2 under Rashid
Atul and Daniel both have more than 50% trainees meeting the AHT target of 300 seconds
More than 75% of male trainees are meeting the AHT target of 300 Seconds under Atul and Female trainees have lesser AHT vs Male
trainees under Daniel
In Morning & Evening shifts, 50% agents are meeting AHT target and in night shift less than 50% are meeting their target of 300 seconds
In Evening shift, 100% agents are meeting their target under Atul & in night shift more than 75% agents are meeting AHT target of less
than 300 sec trained under Rashid
More than 50% agents in L1, morning shift and L2 evening shift are meeting the AHT target of 300 Seconds. In L1, night-shift,
only 25% are meeting AHT target of 300 Seconds
Females in evening shift and Males in morning shift are meeting the target. In night shift, neither males nor the females
are meeting the AHT target
More than 50% agents at C6 evening and morning shift are meeting target. And in night shift more than 25% agents are
meeting the AHT target of 300 sec
