19 Support Segula Organizing Team structure System Requirements & Architecture Project Management 19

20 Team Structure Team Structure Project Management STE Organization Public relations (STELLA) Operations & Finance System Architecture Project Manager: Focus on time and efficient planning of Resources Operations Manager: Focus on timely delivery of components and management of the limited budget System Architect: Focus on total System Design, state-of-the-art solutions and safeguards the technical quality The Project Organization was introduced to focus on: Time, Budget and Quality 20

21 System Architecture Define Requirements - Identify what functionality shall be developed 21

22 System Architecture Validation Tests - Develop tests to validate the system requirements during the definition phase - Validates completeness of requirements - Generates additional requirements for validation purposes Example validation test 22

23 System Architecture System Architecture - Develop an Architecture that can fulfill the requirements - Decompose functionality to modules to enable concurrent engineering (TTM) - Define budgets for each module to secure overall requirements - Guard and define interfaces between car, environment and users - Guard and define interfaces between submodules - Recognize critical modules and parts 23

24 System Architecture System Architecture - Develop an Architecture that can fulfill the requirements - Decompose functionality to modules to enable concurrent engineering (TTM) - Define budgets for each module to secure overall requirements - Guard and define interfaces between car, environment and users - Guard and define interfaces between submodules - Recognize critical modules and parts 24

25 System Architecture System Requirements & Architecture WHY? STELLA COMPETITOR Setting good requirements & decompose to modules enables concurrent engineering, prevents trial loops and need for quick fixes 25

26 Case - Battery Pack

27 Design goals - requirements Veilig en betrouwbaar Geïntegreerd in mechanisch ontwerp Actieve monitoring (BMS) Efficiënt en krachtig Grote accucapaciteit Grote actieradius Stella Praktisch Geïntegreerde charger

28 Twee Battery Packs EiG pack Capaciteit: 11,3 kwh Al in ontwikkeling Goedkoper Panasonic pack Capaciteit: 15 kwh Extra werk en kosten Ongetest

29 Systeem integratie Mechanisch aspect Veilige behuizing in backbone Lekkage en acceleratie bestendig Goede koeling d.m.v. luchtkoeling Elektrisch aspect Software aspect

30 Systeem integratie Mechanisch aspect Elektrisch aspect Geïntegreerde charger Goede integratie Veiligheid: elektrische isolatie d.m.v. noodknop Software aspect

31 Systeem integratie Mechanisch aspect Elektrisch aspect Software aspect Realtime monitoring Veiligheidscontrole Betrouwbare SOC (State of Charge) Stella kent haar batterij

32 Prestaties Panasonic pack Actieradius single charge s nachts: 430 km Australië: 909 km Topprestatie Gemiddeld hele traject: 72 km/h met 3 personen Piek prestatie: 120 km/h met 4 personen

33 Het geheim Requirements en testen zijn vooraf duidelijk Alle onderdelen werken samen Goede planning: test en weet wat je batterij pakket doet

34 Project Management Planning tools in Definition Phase - Critical path identification & Risk Management in Definition Phase A MS Project Planning was setup to: - Identify the Critical Path - Optimize the Resource Allocation Risk identified early in the Project & Actions were planned to lower the risk and impact on: - Timing - Quality - Budget 34

35 Project Management SCRUM in (Concept) Design Phase - SCRUM methodology introduced in Design Phase Burn-down chart SCRUM Methodology: Improved team-work in Electronics & Software group: - Common Goal - Supported each other to reach the common goal - Iterative approach (Safe, Drive, Finish & Win) 35

36 Project Management Tools used in Integration Phase - Integration Scheme in Integration Phase Integration scheme: - Oversight of the integration steps - Modules that passed their unit-test Seen were accepted for integration Before? Integration Scheme 36

37 Project Management Tools used in Test Phase Processes introduced: - CCB installed to focus on CRITICAL issues - Working in shifts to optimize the usage of the limiting resource: Stella - Issue forms describes issue and in which configuration found - Configuration sheet described the current status of the car 37

38 Results Result? SEGULA is proud on coaching the WINNING team 38
