5 Project Management A space project typically comprises a space segment and a ground segment which are implemented in parallel. They rely on, and have interfaces with the launch service segment. These three segments comprise a space system. Project planning includes all the processes implemented to plan and execute a Space Project from initiation to completion, in a coordinated, efficient and structured manner Standarized procedures are defined to implement processes. Procedures should ALWAYS be tailored to specific scope/needs of each project. Good Management Practices (GMP) should be ALWAYS based on good equilibrium between requirements compliance, schedule and cost October 2012 Page 5

48 Explaining Configuration According ISO (Quality Management Systems Guidelines for Configuration Management): A configuration item (CI) is an aggregation of hardware, software, proccesed materials, services, or any of its discrete portions, that is designated for configuration management and treated as a single entity in the configuration management process. A CI is a product component (including hardware subsystems, software packages, cables or interfaces) that meets the following conditions: It is well defined by an established set of functional, physical and performance specifications It is accepted in accordance with its set of specifications (the baseline) It can be tested as a unit Any uncontrolled changes in its specifications can produce severe changes in the instrument high level performances October 2012 Page 48

49 Explaining Configuration Management According MIL-STD-973: Configuration Management (CM), as applied to CIs, is a discipline applying technical and administrative direction and surveillance over the life cycle of items to: Identify and document the functional and physical characteristics of configuration items Control changes to configuration items and their related documentation Record and report information needed to manage configuration items effectively, including the status of proposed changes and implementation status of approved changes Audit configuration items to verify conformance to specification, drawings, interface control documents, and other contract requirements CM establishes the procedures to ensure the traceability of the final produced item performances to the defining specifications, as well as the conformance of the defining documentation with the final item. It also enable all the engineering team to use identical data, in the same controlled status, during the instrument development cycle CM IS THE MANAGEMENT OF THE TECHNICAL DESCRIPTION OF CIs October 2012 Page 49

50 CM Objectives Know at any moment the technical description of a system and its components, using approved documentation Ensure the traceability of the CI performances to the defining specifications Facilitate the consistency and control of internal and external interfaces Verify that documentation is and remains the exact image of the products it describes Identify the desired configuration and the as-built configuration, in order to recognize discrepancies detected during production, delivery or operation of the product Enable any user to know the operational capabilities and limitations of each product item and, in case of variances or non-conformances, to know which items are affected Provide the engineering team with the same technical data, in the same controlled status, during the instrument development cycle Configuration Management is a product control function that provides surveillance through all phases of the product life-cycle October 2012 Page 50

51 Baseline Definition The set of documents completely describing each CI at each project milestone is called a Baseline When the set of documents related to each CI has been approved it becomes part of the CI baseline, and it may be considered that the CI in turn has been also formally accepted at the level defined by the milestone Configuration Items divide a complex product or system into manageable segments and components Configuration Baselines divide the project phases for concept evaluation (feasibility), development (preliminary definition), design (detailed definition), production and utilization of a product into manageable segments by defining specific reference configurations during the life-cycle of a product and provide agreed departure points for further evolutions CM is based on the establishment and control of different baselines for each CI, which in turn are constituted by configuration documentation (documents and drawings maintained under configuration control) October 2012 Page 51

52 Project Phases and Baseline Definitions October 2012 Page 52

53 CM Tasks Configuration (or baseline) identification It includes the following activities: Select CI s and define their Configuration Documents Establish means for identifying and codify products and documentation Establish configuration baselines Configuration control It is the process of controlling changes to any approved baseline. Modification of a baseline shall be made according approved DRs and NCs to ensure its traceability Configuration verification It is the process of verifying that resulting CIs conforms to the preceding approved baselines, and that baseline documentation is current and accurate. Configuration verification is accomplished by technical reviews at defined milestones Configuration accounting It is the task of maintaining, releasing, distributing and storing configuration documentation. It is based on the management of documents database October 2012 Page 53

54 Configuration Control It is the process for controlling the evolution or change from agreed baselines It includes the preparation, justification, evaluation and implementation of engineering and contractual changes, deviations and non-conformities Changes shall be formally initiated, assessed and decided based on reported DRs and NCs. All authorized changes shall be implemented, verified and recorded All released baseline documentation is subject to configuration control. As such, no formal change can be generated without an approved baseline October 2012 Page 54

55 Baseline Documents A list of documents to be delivered at established project reviews (including configuration and no-configuration documents) shall be included in the Deliverable Items List (DIL) A detailed list of all the configuration documents approved on each baseline shall be included in the Configuration Item Data List (CIDL). The CIDL serves as a point of departure for the control of subsequent performance, design and build changes Draft issues of baseline documents can be distributed in earlier phases of the project for information and informal reviews if needed October 2012 Page 55

56 Documentation Management Creation and Revision During this phase the content of a document is established and the documentation reference is assigned. Configuration control process should be applied to configuration controlled documents Document status shall be In Preparation Review When the document is complete, it is submitted for review and approval as required. The review panel either confirms that the content complies with the applicable requirements, or states the identified discrepancies together with the proposed resolution. In the later case, the document is returned for incorporation of comments and resolution of discrepancies. Document status shall be In Review Approval and Release Approval (either in person or by electronic signature), ensures that a. The document has not been modified after its approval, and b. The author accept his responsibility for the content At the end of this phase the document reaches the status of Released October 2012 Page 56

70 Issues Potentially Impacting the Risk Requirements or specifications not clearly defined or not verifiable The schedule doesn t provide enough time to complete the project Activities and/or tasks undefined Long-term activities are potentially risky because they can produce schedule delays easily Communication is not flowing between working groups The project cost exceeds the allocated budget There are planned activities at undefined costs The deliverables are not clearly defined The allocated staff is not suitably skilled to develop all the project tasks at low or no risk The proposed design is non-proven, in the sense it has not been used previously in other instruments, or it is not well documented The proposed concept is very complex The internal and external interfaces are not well defined The use of non-standard materials The use of components not specified for the working conditions The use of non-standard manufacturing processes It is not well defined the procedure to accept individual components The verification procedures are not well defined or are difficult to be performed The instrument operation is not possible or it is not well defined Maintenance is complex or it is not feasible October 2012 Page 70

71 Risk Likelihood Scoring Scheme Score Likelihood Likelihood of occurrence E Maximum Certain to occur, will occur one or more times per project D High Will occur frequently, about 1 in 10 projects C Medium Will occur sometimes, about 1 in 100 projects B Low Will seldom occur, about 1 in 1000 projects A Minimum Will almost never occur, 1 of or more projects October 2012 Page 71

72 Risk Impact Scoring Scheme Score Severity Performance Cost Schedule 1 Negligible Small reduction in performance Cost increases below 5% Minor impact on schedule 2 Significant Some reduction in performance Cost increases from 5 to 15% Final delivery date slip less than 6 months 3 Major Technical specifications could not be achieved Cost increases from 15 to 30% Fine delivery date slip between 6 months and one year 4 Critical Technical specifications are not achieved Cost increases over 30% Final delivery date slip more than one year 5 Catastrophic Leads to termination of the project October 2012 Page 72

73 Risk Levels Likelihood Risk Index: Combination of Severity and Likelihood E Low Medium High Very High Very High D Low Low Medium High Very High C Very Low Low Low Medium High B Very Low Very Low Low Low Medium A Very Low Very Low Very Low Very Low Low Severity Red Yellow Green October 2012 Page 73

74 Risk Actions A Risk Mitigation Plan (RMT) should be established, at least, for the risk events having High or Very High Levels A RMT could be also defined for Medium risk events, if it is decided by the Risk manager (or the PM). Events having Low or Very Low severity are considered not risky for the project development Two different kind of actions should be included in the RMP: Preventive Actions that must be taken to reduce the likelihood of risk s occurring Contingency Actions that must be taken to reduce the impact should the risk occur October 2012 Page 74

75 Risk Register (Frida) FRIDA RISK REGISTER (Management & System Risk) Summary Description Score Mitigation Plan Performed Actions ID Subsystem Item Risk Event Description of Impact Event Impact Risk Preventive Actions Deadl Contingency Actions Deadl Performed Actions Date Status 1.1 Management Cost Gloabl cost is not including all project items. Some critical elements (like IFU) have not a detailed estimate of cost Cost over run up to the estimated contingency (20%) MODERATE Cost will be reviewed and updated after project review. Extra funds are requested from national agencies of the involved countries 1.2 Management Schedule Present schedule is not including the prototypes development Schedule delays MODERATE Schedule will be reviewed and updated after project review 1.3 Management / System Manpower and Schedule Coordination of engineering activities across various institutions Delays, poor performance, noncompliances HIGH Good system engineering practices implemented in the project. Configuration and interfaces control are critical areas. Management centralized activities and a well defined chain of responsabilites are also critical points 1.4 System Intranet database Sharepoint documents database could crash due to computer problems or to management errors Unavailability of project documentation causing project delays LOW Computer hardware and sharepoint software is properly maintained and operated. A recovery procedure is implemented and validated 1.5 System Intranet database More effort needed than currently allocated for database daily maintenance Updated documentation not available on line MODERATE Database will be operated by a dedicated and trained person from the computer department at IA- UNAM 1.6 System Product Assurance Insufficient PA/QA control to More effort needed than currently ensure the instrument allocated for PA/QA (now shared development within time, cost and with other system activities) specifications HIGH A detailed Product Assurance Plan shall be produced and run. More effort shall be assigned to monitor PA/QA activities October 2012 Page 75

76 Risk Management Documentation Two key documents should be established: Risk Management Plan, describing the implementation of the risk management process Risk Assessment Report, identifying risk issues, assessing risk impact and describing mitigation actions (when required) RISK SHOULD BE CONTINOUSLY ASSESSED THROUGH ALL LIFE CYCLE October 2012 Page 76
