Parameter
Atlassian Product
In this step, you choose one out of four Atlassian products available for Data Center so that a TCO calculations makes sense by employee productivity or similar. Currently: Jira Software, Jira Service Desk, Confluence, and Bitbucket. The identity service Crowd is not considered.
Should you apply different products, then perform the calculation product separately based on the various user groups and further parameters such as full costs. When overlapping two user groups, i.e. Jira Software and Confluence you might have to aggregate the related staff costs. The TCO calculator only pinpoints the values. A detailed analysis with reliable results can be calculated individually to a specific customer project.
Number of active users
To generate the figures for productivity the number of named active users is required. The calculator selects the right user tire and prices. There is a considerable difference in the user tire between the products of server and Data Center.
Full costs Employee/hour
Here you should enter the total costs per employee (possibly averaged by active users). These figures point the expenses of the existing employee. Probably this understanding of numbers can differ from company to company. Mostly considered is the salary, directly attributable expenditure such as a company car.
Product usage
Details regarding the applied product as measured in the percentage of employees working hours. In case of downtime, consider if the employee can skip to other valuable no system related work. Here you might also choose an average value. Instead, work with a smaller amount. The cost will increase the more the product will add to the value chain.
Opportunity cost / h
This value records the loss of a potential profit caused by downtime. Such as collection and processing of an order, delayed invoicing (loss of interests/liquidity) or the not performed service itself (a product cannot be delivered to the customer). This can also be external costs such as a failed collected delivery. The closer the product linked to a particular toolchain the higher those opportunity costs can get.
Case study: Your company makes an annual turnover of $ 10 mil due to downtime the company cannot perform. Next, to the employee costs, you will have additionally $ 4,980 per hour (when we say you have to reach this target volume hourly by 252 working days annually, with 8 hours). During short downtime you can partially compensate with overtime, so you have the option to choose a percentual target of the total value ( i.e., 50%) in the TCO calculator.
Hardware costs Server p.a.
Required annual total costs of physical/ virtual servers (rental or depreciation, maintenance costs, support costs)
Net working hours p.a. EE
Here you add the actual spend productive working hours lets say 202 working days / 8h (next to the holiday, periods of illness, internal events or training). In Case of discrepancy between headcounts and the number of part-time employees (essential for the user tire) choose an average value.
The multiplier for Data Center to server/scaling of the hardware
Due to the technical architecture required for Data Center, you would need more physical and virtual servers comparing to the single Server version (multiplier). Therefore each Data Center server does not have to be a high-performance server (scaling refers to the hardware costs)
Server availability
Server product availability percentage outside of the planned maintenance cycles (updates, maintenance and more).
Data Center availability
Data Center product availability percentage outside of the planned maintenance cycles (updates, maintenance and more). Please note that generally there is no maintenance slot necessary (zero downtime). In case of downtime applies a fail-over.
Productivity gain
With the opportunity of so-called 'load-balancing', the response time is better within the processes of Data Center which in turn increase in the productivity of the employee. Even when, in individual cases, these values are shallow in the long term experience and with a large number of users you will have substantial time savings. But the financial impact will only come into effect when the time is productively used (avoiding expenses such as no recruiting of a further employee in case of increasing business or the opposite redundancies of employees due to stagnating or even falling business). This event will result in negative values within the TCO calculator because you avoid costs (see the previous brackets).
Maturity
The maturity of the TCO calculation.
Results
License acquisition
This position displays the purchasing costs regarding license and user tire depending on the product version. Also included are the maintenance costs for the first year.
Maintenance maturity
Maintenance costs from the second year until termination. Data Center based on a subscription version, so the prices merely repeated.
Total license costs
Amount of the first two licenses- / maintenance position.
Operating costs
Server hardware is operating costs of total term. Data Center is incl. Multiplier and scaling.
Total direct costs
The sum of listed individual positions related to the full term. These costs are directly associated with the acquisition and with the operation of the software.
Downtime costs
This is the result of Number of active users * Full costs Employee/hour * Product usage * Networking hours p.a. EE * Maturity * (100% - 'availability')
Only the downtime of the hardware server is taking into account.
Opportunity cost
Are: Opportunity cost / hour * (100% - 'availability') * Maturity * 252 days* 8hs.
Productivity gain
Calculated as followed: Full costs Employee/hour * Networking hours p.a. EE * Number of active users * Maturity *Product usage *productivity gain.
Total Costs
Sum of the previous three positions and the total direct costs.
