Silver Software has wide experience of the Safety Engineering processes, tools and techniques used to manage, develop, analyze and evaluate high-integrity systems across a wide spectrum of safety critical industries. Silver Software is accomplished at systematically analysing systems in order to evaluate and reduce risks. Although every project is unique, in general the techniques used in the safety lifecycle can be grouped within the following overlapping phases:

Silver Software has wide experience of the Safety Engineering processes, tools and techniques used to manage, develop, analyze and evaluate high-integrity systems across a wide spectrum of safety critical industries. Silver Software is accomplished at systematically analyzing systems in order to evaluate and reduce risks. On one hand acknowledging that every project is unique; in general the techniques used on the other hand during, a safety lifecycle can be grouped within the following overlapping phases :
|
|
• |
Preliminary Hazard Analysis |
|
|
During the initial stages of the development lifecycle, the hazards are identified and analysed. The associated risks are classified and measures drawn up to either eliminate or reduce to a tolerable level, those risks that are unacceptable. Proven predictive and target-setting techniques are used, including ALARP (As Low As Reasonable Practical)
|
|
|
|
Whilst integrating and testing the system, the identified hazards are reassessed to ensure that each has been sufficiently addressed. Further analysis confirms the extent to which the design meets the requirements.
|
|
• |
System Safety Assessment |
|
|
During the design, decomposition and implementation stages the system is analysed to determine failure causes. The results are used to guide further safety analysis and inform the design. Safety related risks are managed, tracked and revisited when changes occur. The system is also assessed against requirements and relevant standards.
|
|
• |
Safety Case Compilation |
|
|
Building a safety case is the process of combining evidence to provide an assurance of system safety. Silver Software has experience in the use of graphical notations such as Goal Structuring Notation for expressing the structure of an argument. |
|
Our systematic safety engineering approach allows early risk appreciation, delivering significant cost benefits to our customer. We invariably achieve precise results on time, to budget and with complete client satisfaction. |
