EN 16601-10:2015 (E) 6 Introduction Project planning and implementation is the project function, encompassing a coherent set of processes for all aspects of project management and control. This is done by:

• establishing the project requirements and constraints derived from the mission statement. • defining phases and formal milestones enabling the progress of the project to be controlled with respect to cost, schedule and technical objectives (i.e. project control function). • defining project breakdown structures, which constitute the common and unique reference system for the project management to:  identify the tasks and responsibilities of each actor;  facilitate the coherence between all activities of the whole project;  perform scheduling and costing activities. • setting up a project organization to perform all necessary activities on the project.

EN 16601-10:2015 (E) 11 4 Principles 4.1 Project planning 4.1.1 Introduction Project planning and implementation encompasses all of the processes carried out in order to plan and execute a space project from initiation to completion at all levels in the customer-supplier chain in a coordinated, efficient and structured manner. It is a project wide activity receiving inputs from all project disciplines and involving close co-operation across the project domains. A space project typically comprises a space segment and a ground segment which are implemented in parallel (see ECSS-E-ST-70). They rely on, and have interfaces with the launch service segment. These three segments comprise a space system. In principle, a proposal to initiate a space project can be raised by any party. However, the most common initiators are: • individual governments, or co-operation between a number of governments; • national, or international space agencies, either singly or collectively; • national or international scientific communities; • operators of commercial space systems. In this ECSS standard, the top level customer is defined as the organization responsible for generating the top level space segment and ground segment business agreements and for interface arrangements with other external space system elements. The following clauses 4.1.2 to 4.1.11 describe the key elements to be addressed, assessed, and balanced when planning a project. 4.1.2 Purpose and objectives of the project The purpose and objectives of the project are defined by the project initiator in the mission statement which includes key performance parameters and technical and programmatic constraints to be applied to the project. They are normally coordinated with the top level customer, if one has been assigned. SIST EN 16601-10:2015

EN 16601-10:2015 (E) 12 4.1.3 Availability of and need to develop new technologies This is an assessment carried out jointly by the customer and supplier to identify the availability of scientific and technological know-how and the technology needed to implement the project. The result of this assessment, which can be a significant cost and schedule driver, is a major input to the assessment of required resources and facilities and to the subsequent technical and programmatic risk assessment. 4.1.4 Availability of and need to reuse existing equipments/products This is an assessment of the feasibility of reusing existing products and is typically carried out as a direct response to a customer requirement. The result of this assessment, which also can have a significant influence on cost and schedule is a major input to the assessment of required resources and facilities and to the subsequent technical and programmatic risk assessment. 4.1.5 Availability of and need

for human resources, skills and technical facilities This is an assessment carried out jointly by the customer and supplier of the resources, skills and facilities required to implement the project. The result of this assessment shows if required resources, skills and facilities are adequate, or if additional skills, resources, or facilities are needed to complete the project.

4.1.6 Risk assessment The initial assessments of the technical and programmatic risks of a project are carried out by the customer, based on the project initiator’s inputs with respect to the purpose and objectives of the project, together with the identified technical and programmatic constraints to be applied to the project. The initial assessment is subsequently regularly expanded to include other relevant parameters as they become available, and as the project matures. Comprehensive risk assessments are conducted at each major project review. 4.1.7 Development approach The development approach for a project is jointly defined by the customer and supplier to comply with the project initiator’s mission statement, requirements and constraints, and balancing these with the outcome of paragraphs 4.1.3 to 4.1.6 above.

4.1.8 Project deliverables The customer has the responsibility for defining the deliverable products, needed to meet the project initiator’s mission statement, taking into account the assessments noted in clauses 4.1.4 to 4.1.7 above. SIST EN 16601-10:2015

EN 16601-10:2015 (E) 13 4.1.9 Customer requirements and constraints

Customer requirements and constraints are prepared by the customer based on the outputs from 4.1.2 to 4.1.8 above and put into a format suitable for direct application in an invitation to tender (ITT). They address technical and programmatic requirements, as well as political, commercial, and industrial constraints to be applied to the project and collectively represent the project requirements documents (PRD). 4.1.10 Project requirements documents (PRD) The project requirements documents are an integral part of an ITT, request for proposal (RFP), or request for quote (RFQ) prepared and released by a customer to potential suppliers.

The PRD typically comprise • Statement of work • Technical requirements documented in Technical Requirements Specification, as defined in ECSS-E-ST-10-06 • Management requirements • Engineering requirements

• Product assurance requirements • Programmatic requirements • Other, project specific requirements (e.g. geographical distribution, model philosophy to be applied) • Documents requirements list (DRL) • Tender requirements Under the ECSS system, management, engineering and product assurance requirements are contained in the M, E, and Q standards, progressively tailored by each customer in the customer-supplier chain to reflect the type and phase of the project covered by the business agreement, as well as the scope of the suppliers’ tasks required by the PRD. 4.1.11 Project management plan The top level project plan is the project management plan which defines the project management approach and methodology to be used throughout the life cycle of the project, together with an overview of all elements of project management disciplines. It includes the definition of the system engineering and product assurance management approach or provides references to separate system engineering and product assurance plans which together make up the total planning documentation used to implement a project. SIST EN 16601-10:2015

EN 16601-10:2015 (E) 14 4.2 Project organization 4.2.1 Introduction The establishment of a well structured and coherent organizational structure for implementing a project at all levels in the customer-supplier chain is a key factor for ensuring an effective and efficient management approach. At each level in the customer-supplier chain a project organization can be built as a self-standing project team containing all necessary disciplines within the team structure or, more often, can be built around a core project team containing key project functions with other necessary functions being provided from outside the project team as external support. Irrespective of the organizational approach followed for a project, the elements summarized below are relevant at all levels in the customer-supplier chain. 4.2.2 Organizational structure It is essential that the project organizational structure is arranged to include all disciplines essential to implement the project with well defined functions as well as clear reporting lines, inter-relationships and interfaces. All project actors below the top level customer and above the lowest level supplier(s) have the roles of suppliers and customers, and their organizational structures are constructed to accommodate both roles. The organizational structure provides a clear and unambiguous definition and allocation of individual roles and responsibilities together with the necessary authority to implement these within the internal project set–up as well as towards project external interfaces. 4.2.3 Communication and reporting Effective means of communication are essential tools for ensuring clear and efficient inter-action between all project actors, as well as between the project team and its external interfaces. Information technology is the primary means for the exchange of information. Communication serves initially to provide clarity about the project’s goals and objectives and subsequently, to support the day to day work of the project team. Regular reporting is an important tool for exchanging information concerning the progress of the project. 4.2.4 Audits Audits are independent examinations to determine whether processes and procedures achieve the specified objective. They are an essential tool to identify problem areas.

EN 16601-10:2015 (E) 15 4.3 Project breakdown structures 4.3.1 Introduction Project breakdown structures provide the basis for creating a common understanding between all actors. They break the project down into manageable elements as described in the following clauses 4.3.2 to 4.3.7. 4.3.2 Function tree The function tree is the breakdown of the system performances into functions. Each function is decomposed into sub–functions independent of the type of products involved. The “function” approach is applied during project start–up or during the system definition phase. More details about the function tree are given in ECSS-E-ST-10, function tree DRD. 4.3.3 Specification tree The specification tree defines the hierarchical relationship of all technical requirements specifications for the different elements of a system or product. More details about the specification tree are given in ECSS-E-ST-10, specification tree DRD. 4.3.4 Product tree The product tree is the breakdown of the project into successive levels of hardware and software products or elements, articulated to perform the functions identified in the function tree. However, the function and the product tree do not necessarily mirror each other. The product tree includes the development models, the GSE, the integration tools and test equipment, and external items necessary to validate the end product and ILS items. It includes items submitted to customer configuration control and items that are the subject of a technical requirements specification. The product tree forms the basis for the elaboration of the project work breakdown structure. An example of a product tree is shown in Figure 4-1.

Figure 4-1: Product tree example 4.3.5 Work breakdown structure (WBS) The WBS is the principal structure used in managing a project and provides a framework for managing cost, schedule and technical content. It divides the project into manageable work packages, organized according to the nature of the work by breaking down the total work to be performed into increasing levels of detail. The WBS is derived from the product tree, selected elements of which are extended to include support functions (i.e. management, engineering, product assurance) and associated services (e.g. test facilities). An example of a WBS is shown in Figure 4-2. SIST EN 16601-10:2015

Control work packages are identified by the supplier at the level in the WBS where visibility and control is required, and for which reporting is to be performed. The control work packages represent the total work-scope and are agreed by the customer. The work of each supplier is explicitly identified in the work breakdown structure by at least one control work package. 4.3.7 Organization breakdown structure (OBS) The OBS depicts the proposed project organization, including the interface and contractual responsibilities, as opposed to company organization breakdown structure, which depicts the functional aspects of the company. The project OBS shows the key personnel and the assigned responsible parties for each work package in the WBS. SIST EN 16601-10:2015

EN 16601-10:2015 (E) 18 4.4 Project phasing 4.4.1 Introduction The life cycle of space projects is typically divided into 7 phases, as follows: • Phase 0 - Mission analysis/needs identification • Phase A - Feasibility • Phase B - Preliminary Definition • Phase C - Detailed Definition • Phase D - Qualification and Production • Phase E –Utilization • Phase F – Disposal A typical project life cycle is illustrated in Figure 4-3.

Project phases are closely linked to activities on system and product level. Depending on the specific circumstances of a project and the acceptance of involved risk, activities can overlap project phases. At the conclusion of the major activities and the related project reviews configuration baselines are established (see ECSS-M-ST-40).
