    The activity's goal is to realize a preliminary planning for the entire project.

    To do so the marginal conditions (from activity PM1.2 - Definition of Project Criteria and Development Strategy ) and the project-specific V-Model (relevant activities and products) must be taken into consideration.

    The planning must be set up in several steps:

    Since special requirements are expected of the development process and the development environment from a certain criticality level, it might be necessary that tools having the required functionality or quality are available as soon as possible.

    The staff must be experienced enough to generate an analysis of the cooperation of the selected IT measures (security functions and security concepts). The same staff must also be able to realize efficiency analyses for the mechanisms and methods selected for the implementation of the security functions and security concepts.

    In the case of higher criticality, the staff available must have sufficient experience with semiformal or formal specifications.

    If an accompanying evaluation is to be realized, the cooperation of the evaluating staff member and the BSI must also be considered in the planning.

    * Effort Planning and Time Scheduling

    This part of the project planning must establish planned values for deadlines, planning sections and efforts, based on the organization planning in the Project Manual; this is the initial preliminary planning for the project. Any specifications of the customer with regard to interim and final deadlines as well as to milestones have to be entered into the Project Plan. To make this easier, empirical values, expressed in percent, might be used for the efforts of QA, CM and PM.

    Detailed planning for the following planning section must be realized during the corresponding initialization.

    * Planning Baselines

    The products to be generated during a project have to be combined into defined baselines. The definition of milestones within a project is the criterion for the determination of baselines.

    For products within a baseline that are subject to dynamic processing (refinement or adding of statements) the planned processing status of the corresponding products must be established.

    * Planning Phase Reviews

    The phase reviews relevant in the project have to be defined. The reference points for the phase reviews may be baselines or the decision for the selection of a contractor.

    * Resource Planning

    Among the organizations participating in the project, it must be defined (by using the activities/roles matrices) which persons are in charge of the realization of which project activities, and which resources have to be available for the individual tasks. It must also be established for which period these persons and tools are required, and to which capacity utilization rate.


    In order to guarantee that the planning data are as realistic as possible the following points should be considered: Another way to arrive at realistic planning data is to analyze the Project Histories of similar projects that have already been completed or at least are further advanced. Thus, it is possible to gain conclusions for the current project. This means that the causes of previous problems must be searched for in existing history and statistical documents.

    One of the important planning points is the coordination of SWMM measures, subcontractors and subprojects. However, the coordination is not limited to project or product-internal matters; it must also be generally applied since this is the only way to reuse (sub-) products and to make the most of the experience of individual staff members.


    Within the scope of the project initialization preliminary planning is performed for the entire project period. Detailed planning takes place as accompanying activity, usually at the beginning of a planning section.

    (1) The state "b. proc." merely reflects the CM aspect. The authorization of the Project Plan by the project management responsible is nevertheless required, possibly with the participation of the QA Manager.

    (2) Method FMEA is to be applied if
    - high restrictive planned values (deadlines, costs) or
    - high requirements
    have to be fulfilled in the project.
