KPA duties
TASK Complexity
Overview
Customer:
? Requirements Analysis: Play an active role in requirements analysis. This means that we need to provide comprehensive input on requirements definitions, marketing plans, marketing roadmaps, marketing strategy, as well as, department strategy. Review all Business requirements documentation from the perspective of whether they illustrate proper customer experience and relevant use cases.
? Business Project Tracking And Management: Keeping of all project progress and provide project status updates, as well as, ensuring that feedback is provided on resourcing versus project load. Track progress of all the phases of a project by identifying the high level milestones and reporting back regularly against these milestones ensuring that a full chronology of events (status, decisions and risks) are kept for each.
? Product Ownership: Work with line management to ensure that that product documentation and reporting is in place for product assigned to the individual.
? Technical Landscape And Business Proposals Presentations: Present underutilized capabilities of systems, product ideas, future technical landscapes to the business as regularly as possible.
? End-to-end Solution Architecture.
Internal:
? System Architecture And Functional Requirements Specifications: Ensure that each system or logical group of systems have functional requirements specifications that are updated for each new requirement.
? Reporting And Data Management: Ensure that all systems and products have reporting.
? System Architecture, Capacity, Utilisation, Health, Roadmap And System Evolution Presentations: Deliver quarterly reports for all systems which includes a views on system topology, health, functioning, products supported and all projects effecting the system evolution to date.
? System Documentation: Ensure that all systems (or set of systems) are properly documented. Documents include technical architectures, installation and operations guides, third party interface documents, ATP documents and topology overviews.
? Internal Project Tracking And Management: As per Business Project Tracking except that the business does not need to understand all the details of internal projects, but need a view so that they are aware of these impact on their projects.
? Capacity And Event Plans: Ensure that documentation is maintained that identifies capacity upgrades that are required.
? Policies, Processes And Procedures: Ensure that policies and procedures around systems and products are in place in order to ensure the organisation maintains its ISO status.
? End-to-end Testing: Ensure that as many systems as possible are put in place to test the customer experience.
? Incident Or Event Reporting: Major network issues (incidents) and major events require reports.
? System Architecture, Capacity, Utilisation, Health, Roadmap And System Evolution Presentations: Deliver quarterly reports for all systems which includes a views on system topology, health, functioning, products supported and all projects effecting the system evolution to date.
? Roadmaps And Strategy: Establish and own roadmaps that form objectives of what to work towards, showing system evolution against service, subscriber growth and product trends.
Financial:
? Billing And Assurance Management: Ensure up-to-date documentation exists showing all record types, and fields and traffic cases.
? Track All Licenses And Hardware: Track all licenses, hardware and work with operations to make sure that all software and hardware support is covered and that license renewals happen.

? Financial Budgeting And Conformance To The Organisation’s Financial And Budgetary Processes: Develop budgets taking into account capacity growth, end-of-life replacements and enhancements in system performance. Comply with the organisation’s budgetary and financial processes at all times.
? Reduce OpEx Spend: Take the initiative to reduce OpEx where possible.
People (Learning And Growth):
? Knowledge Management: This is the set of proactive activities that one needs to undertake to support an organisation in creating, assimilating, disseminating, and applying its knowledge. Knowledge management is a continuous process to understand the organization’s knowledge needs, the location of the knowledge, and how to improve the knowledge.
? Risk Management: It is each person’s responsibility to ensure that the organisation’s investment is protected such that risk to the organisation is minimal whenever personnel leave due to natural attrition or when the organisation needs to swap vendor systems and solutions for whatever reason.
Supervisory / Leadership / Managerial Complexity
Self Management:
1. Self Management is a Key discipline that a Systems Engineer must take into cognisance. The MTN culture requires one to be self managed in that the Systems Engineer must not expect the Senior Engineers and Line Management to assign individual tasks. Often time one will simply be assigned a project and will be expected to work on it almost completely alone and will be required to see the project through from start to finish.
2. Work with Senior Systems Engineers and Line Management to maintain morale within Payment Systems team
3. The Systems Engineer must make sure that he/she adheres to the principles of the Companies values at all times
Project Management:
1. The Systems Engineer is required to track projects progress for projects where he/she is the lead (through all phases) by identifying the high level milestones and tracking delivery and deadlines.
2. The Systems Engineer must ensure that each key phase of the project lifecycle is completed properly
Mentoring and Knowledge Management:
A Systems Engineer must maintain open, consistent and professional communication amongst all Payment Systems team members including colleagues in other Network Group departments as well as with Marketing and the Business by and large.
Vendor Management:
The Systems Engineer must assist the Senior Systems Engineers and Line Management to manage Vendor performance which must but be monitored. Regular meeting must be held with all vendors to go through all issues. Healthy vendor relationships must be maintained at all times
Role Complexity:
This role constantly requires the incumbent to perform duties that are outside the traditional technical role. Additional complexity is required from this role that is not usually inherent in such a position. The organisation regards a background in programming, system architecture, Unix/Linux operating systems, systems administration, storage administration, database administration key to becoming an effective person in this department
