Simultaneously prepare draft user requirementsSimultaneously prepare draft user requirements –Performance –Platform support –Real-time support Implementation of test applicationsImplementation of test applications EvaluationEvaluation Design proposalDesign proposal

7. Software Group 7 So what about ACS?

8. Software Group 8 ACS: Weaknesses & Strengths WeaknessesWeaknesses –Security missing –No generic data archive tool –I/O Integration  Interfacing to low-level drivers could be extended, e.g. for GPIB support  Standard device interfaces: location and how-to?  Catalogue for specific device implementations

9. Software Group 9 ACS: Weaknesses & Strengths (cont.) StrengthsStrengths –Solid architecture –Reuse of available software –Bulk data transfer –Good level of documentation
