| SPM05 - Supporting Cost Estimation |
LPM05 - Kostenschätzung unterstützen
1 Allocation to V-Model and Methods Allocation
V-Model
PM1.5 - Generation of Preliminary Plan
Method
2 Brief Characteristics
This service unit defines the requirements for tools used to support the cost estimation for the project. This is realized on the basis of already available empirical values from earlier projects, project-specific marginal conditions, and by the assumption of future developments.
3 Requirements
3.1 Requirements for Interfaces
| SPM05.I.1 | Granularity | The exchange of control parameters with SWFM01 - Workflow Management is possible for individual closed function packages of the tool by means of a disclosed, documented interface. |
| SPM05.I.2 | Input interface to SPM01 - Managing Project Resources | It is possible to integrate information about resources collected with SPM01 without further transformation directly from the object management in order to be used for the cost estimation. |
| SPM05.I.3 | Input interface to SPM03 - Supporting Tender-Relevant Tailoring | It is possible to integrate project-specific V-Models generated with SPM03 without further transformation directly from the object management in order to be used for the cost estimation. |
| SPM05.I.4 | Input interface to SPM04 - Supporting Planning of the Project Realization | It is possible to integrate instantiations of activity types and resource allocations from project realization plans collected in SPM04 in order to be used for the cost estimation. |
| SPM05.I.5 | Output interface to SPM06 - Supporting Project Control and Steering | It is possible to transmit cost estimations without further transformation via the object management to SPM06 to be used for the project control and steering. |
3.2 Requirements for the Methods Support
| SPM05.M.1 | EMOD - Estimation Models | |
| SPM05.M.1.1 | Cost | |
| SPM05.M.1.1.1 | Fixed costs |
It is possible to enter fixed costs for resources. "Cost" refers to all effort and resource consumption that can be converted into money units. |
| SPM05.M.1.1.2 | Variable costs | It is possible to enter variable costs for resources. |
| SPM05.M.1.2 | Accumulation of resource costs | |
| SPM05.M.1.2.1 | Activity types | It is possible to determine the resource costs with regard to activity types. |
| SPM05.M.1.2.2 | Resource groups | It is possible to determine the resource costs with regard to resource groups. |
| SPM05.M.1.2.3 | Subprojects | It is possible to determine the resource costs with regard to subprojects. |
| SPM05.M.1.2.4 | Time window | It is possible to determine the resource costs for selected time periods. |
3.3 Requirements for Functions
| SPM05.F.1 | Pocket calculator | It is possible to call pocket calculator functions. |
3.4 Other Requirements
| SPM05.O.1 | Experience database |
An experience database is available for the cost estimation. Project characteristics of already completed projects are stored in the experience database. They can be utilized for later cost estimations. |
| SPM05.O.2 | Upward compatibility | It must be possible to process objects generated with an older release of the tool with the later release of that tool, without loss of information and functionality. |
| SPM05.O.3 | Procedural command language | The tool has a procedural command language that can be applied by the user to generate and run macros or procedures. |
| SPM05.O.4 | Complexity | There is no limitation of the complexity caused by the tool itself. |
