Slide 7

ESA/ESTEC, TEC-QQS

SW PA R&D Roadmap: Objectives (1/6)

• Dependability and security in software intensive systemsTo develop:– methods ensuring high-reliability software systems– effectively combinations of software RAMS techniques and methods– methods in support of distributed, dependable hard real-time systems– fault tolerant mechanism and protocols to reduce vulnerability– an approach to estimate security risks based on the detection of

implementation vulnerabilities in software systems security strategies– software PA methods for security-focussed software development

processes– security-based risk assessment methods– security evaluation methods and measurements for open source and

COTS software


Slide 8

ESA/ESTEC, TEC-QQS


• Processes and managementTo develop:– standard process models including quality assurance– software project risk management based on software process

assessment– a software quality assurance approach for FPGA and ASIC design – safety and dependability process assessment models– quantitative measurements of the benefits of process assessment and

improvement– a space specific software risk taxonomy– an approach to risk based software process improvement– requirements and criteria for personnel qualification– a metrication framework for software processes


Slide 9

ESA/ESTEC, TEC-QQS


• ReuseTo develop:– quality assurance approaches for building block-based software

systems– quality assurance approaches for Open Source software (OSS)


Slide 10

ESA/ESTEC, TEC-QQS


• Support to engineeringTo develop:– testing suite adequacy criteria, methods for software intensive

systems– new software PA methods and techniques in support of evolving

software development methods and techniques– a quality assurance approach for automatic code generation– a quality assurance approach for proof-based systems– techniques in support of system evolution– a quality assurance approach for network- and web-based

systems– PA approaches to support agile development models


Slide 11

ESA/ESTEC, TEC-QQS


• Product qualityTo develop:– software product certification requirements and process– approaches for assuring product quality by engaging third party

organizations that ascertain the fulfilment of product quality criteria and produce a written statement as part of the product’s quality evidence

– metrication programs and quality models with emphasis on establishing target values for metrics and clear links between metrics and quality objectives (e.g. for object oriented developments). Requirement quality modelling and metrics

– reliable reliability models for safety- and dependability-critical software components


Slide 12

ESA/ESTEC, TEC-QQS


• Ground segmentTo develop:– software PA approach for large ground segments using

contracted communication services

Summing up

Meet future mission needs in line with ESA goals

– Define objectives to guide software PA R&D efforts.– Justify objectives: Relate to missions, ESA objectives,

drivers– Describe objectives to allow preparation of implementation

plans– Early active involvement and contribution from industrial

partners
