Introduction to IT Services
Most IT professionals do not know how organizations sell their services to the clients. While the topic is of great interest to the presales or architects, as an IT professional, everyone must be aware of the cost calculation.
This write-up highlights a few basic cost calculation components and methods but in future blogs, a more detailed description will be made available.
Let us start with a basic vocabulary related to the IT Services costs.
| FTE | Full Time Equivalent (Considered to be of 8 hours of efforts) |
| Resources | People involved in service delivery |
| Support Window | The anticipated support shift in hours |
| Skill | Technical capability of the resources (DBA, Server admin etc) |
| On-Call Support | Generally considered as support required during off-business hours (outside of agreed support window). |
| Billing Method | Defines the method the way invoices would be generated. |
| ITSM | IT Service Management methodology encompasses people, process, and technology and presents the way the monitoring, incident handling, change management, capacity, and problem management will happen. |
| Governance Model | A governing body structure which includes senior and relevant stakeholders from service provider and client. They together review the service delivery and work towards the improvement the overall quality and other strategic initiatives. |
| Transition Phase | Every new service contract starts from the transitioning of services from an existing vendor or team. This phase is known as the transition or services transition phase. There are different sub-phases to complete the transition of services; Due diligence, Train the trainer, Onboarding of resources, Verification and Creation of Standard Operating Procedures, Sign-off of all the documents, Shadowing of services and reverse shadowing phase, Final cut-over of services to the new service provider. |
| Transformation Phase | This phase revolves around IT infrastructure modernization, data center consolidation or anything which will impact the current IT infrastructure landscape. This phase automatically leads to the revision of managed IT Services. |
| Tenure | Translates to the contract duration. In a general practice medium to large enterprises outsource the managed IT services for 3 to 5 years. |
To understand the concept of service cost, let us consider a simple case where your company has to submit a quote for supporting the following IT infrastructure remotely with the following landscape.
- The client has two data centers in Europe - Primary and DR Site. And, the workloads are equally divided between both the sites.
- The client will have their own people to manage the local DC operations and only remote services are to be outsourced.
- All software, hardware, and maintenance contracts will be owned and managed by the client.
- The service quotes are to be submitted for 5 years for the following inventory,
- 1000 Windows Servers
- 200 SQL Databases
- 350 Linux Servers
- 300 MySQL Databases
- 300 L3 Network Switches
- 50 Large Firewalls
The very first thing to know before creating a service quote is to know how much does it cost your company to offer:
- A generic FTE cost breakup is something like below.
Employee cost 65% Workspace cost 10% Office expenses 1% Hiring cost 4% Bench coverage 10% Hardware cost 2% Software cost 1% Tech support cost 1% Connectivity cost 4% Communications cost 2%

Nice. How about we start a series for CIO/CTO? That category has been empty for a while.
