Defining a Technology Stack
A technology stack makes up a technology grouping.
It is obsolete when one of the technologies that it contains is obsolete.
It can be associated with applications.
Creating a technology stack
To define a technology stack:
1. In the desktop, click the navigation menu then Inventories > Technologies > Technology Stacks.
2. In the edit area, click New.
The technology stack creation dialog box appears.
3. Enter the name of the technology stack and an owner if necessary.
4. Click OK.
Specifying its properties
To specify the properties of the technology stack created:
*Click the technology stack to display its properties.
Among information you can specify:
• its characteristics: identification, support alert, company standard.
• its components (technologies)
• its life cycle
• its owner
• related applications
Support alert
The Support Alert attribute available on each technology compares the official life cycle of a technology (imported from BDNA or defined manually) with its life cycle in the organization.
On a technology stack, the value of this attribute is calculated using the values defined for the technologies that it contains.
• If one of the technologies that it contains is “Not Supported”, the support alert for the stack is "Not Supported".
• Otherwise, if one of the technologies that the pile contains is “Delayed Use”, the support alert for the stack is "Delayed Use".
• Otherwise, if one of the technologies that the pile contains is “Early Use”, the support alert for the stack is "Early Use".
• Otherwise, the support alert for the stack is "Supported".
Company standard (computed)
The Company Standard attribute indicates the organization policy regarding the usage of a technology.
This attribute can take values:
• Approved
• Accept
• Forbidden
• Unknown
On a technology stack, the value of the Computed Company Standard attribute is calculated using the values defined for the technologies that the technology stack contains.
• If one of the technologies the stack contains is "Forbidden", the Computed Company Standard is "Forbidden".
• Otherwise, if one of the technologies the stack contains is "Unknown", the Computed Company Standard is "Unknown".
• Otherwise, if one of the technologies the stack contains is "Accepted", the Computed Company Standard is "Accepted".
• Otherwise, the computed Company Standard is "Approved".
This computed value is providing a reference only. The director of the technology can define a different value for the Company Standard attribute for the technology stack.
Conflicts between a technology stack and its components
The “Gantt chart with conflicts” report is used to view any conflicts between the life cycle of a technology stack and those of the technologies that it contains.
To display this report:
1. Open the properties of the technology stack.
2. Select the page Reporting > IT Portfolio Management > Gantt Chart with Conflicts.
