Learnings from ETOM and TAM
❖ The ETOM was useful for cross checking the process activities
❖ We did not miss anything
❖ The TAM was useful for cross checking Applications functionality
❖ we did not miss anything
The Catalyst process flows for “deployment” are expected to be
Contributing to future “ETOM Resource Capability Delivery processes”
as a reference standard

AI Artificial Intelligence “Powerful auditing”
• System Approvals and Rejections will be audited against the documentation submitted
• Golden Reference documents will be used to check all incoming documents from partners ( Nokia / Huawei)
AI Engine will leverage a combination of• NLP - Natural Language ( Text )• OCR- -Optical Character Recognition (text)• CV – Computer Vision ( images)• CNN-Convolutional Neural Network (image )

CNN-Convolutional Neural Network take in an input image, assign importance to
various aspects in the image and be able to differentiate one from the other.
OCR- -Optical Character Recognition is a technology that recognizes text within a digital image.
NER-Named entity recognition, it is used to extract the specific entities from text that are more informative
