About the 217Plus™: 2015, Notice 1 Spreadsheet Calculator
This tool facilitates the failure rate calculation of up to 10 hardware assemblies and 15 software assemblies, based on the component and system reliability models defined by Quanterion’s 217Plus™:2015, Notice 1 methodology. All models are detailed in the 2015, Notice 1 Handbook of 217Plus Reliability Prediction Models, available exclusively from Quanterion.
The 217Plus reliability calculator uses a common spreadsheet interface, meaning that time spent learning to use it is minimal.
Quanterion also provides product support to all registered users of the original 217Plus™ or 217Plus™:2015 Calculator.
Quanterion recommends purchasing the calculator with the Handbook-217Plus™: 2015, Notice 1, which includes detailed information on the models, the model development background, and associated reference tables and equations. Get both the 217Plus™ handbook and calculator today at a 15% discount.
As an upgrade of the 217Plus™ method, 217Plus™:2015 provided several new component models, updates to model data, and refinements of several model equations. For Notice 1, the original software reliability prediction model has been replaced with the Neufelder Model for software reliability prediction as defined in IEEE Standard 1633-2016 “IEEE Recommended Practice on Software Reliability”. It is recommended that the user obtain a copy of the new 217Plus™:2015, Notice 1 Handbook for detailed information on these models, the model development background, and associated reference tables and equations.
To take full advantage of the Neufelder Model within 217Plus™:2015, Notice 1, you will need to purchase a copy of IEEE Standard 1633-2016 “IEEE Recommended Practice on Software Reliability” from IEEE or an authorized distributor (Quanterion does not sell IEEE Standard 1633-2016). Quanterion also provides product support to all registered users of the original 217Plus™ or 217Plus™:2015 Calculators.
According to the 217Plus™ ‘System Model’ for an assembly, the assembly failure rate is a function of three major elements:
- The summarized failure rates of all hardware components of the assembly/system;
- A Process Grade Factor (PGF) multiplier/accelerant, applied to the hardware summary, and
- An additive Software failure rate term, when applicable.
Using this calculator, each of these values may be calculated for a system of up to ten (10) hardware assemblies and fifteen (15) software assemblies.
The Neufelder Assessment Model correlates more 156 software development practices to defect density which are matrixed to the Quanterion Solutions HDBK-217Plus™: 2015, Notice 1 process grade factors.
