These work products serve as necessary evidence to prove that safety planning for automotive product development has been carried out in accordance with the guidelines of ISO 26262. For example, concept development and material design may not be part of the project. Therefore, we need to mark the areas that fall within the scope of each project. Functional safety compliance is different from other QA such as CMMI, etc. It deals with a very specific functional area and requires certain skills and qualifications. In addition, the achievement of functional safety in automotive software development is evidence-based. These are some of the reasons why safety planning is becoming a crucial part of ISO 26262 compliance. Anyone who has been involved in an automotive project idea and product development understands the importance of project planning. The following table will make the interface agreement more clearly understandable: With ISO 26262, another dimension known as security planning has become an essential part of this project management planning (PLAN-Do-Check-Act). ISO 26262 states that the organization that wishes to implement functional safety in automotive software development must follow a clearly defined safety culture.
In order to achieve functional safety in automotive software development, all parties involved must work towards this common goal. The interaction between project team members should be defined in the Safety Planning Activity Sheet. Because there is an interface between entities as development progresses, the table is called the Development Interface Agreement (DIA). It is important to enter into a robust development interface agreement between the customer and the vendor. A comprehensive DIA not only clarifies the key responsibilities of stakeholders, but can also prevent disagreement and confusion. This is a breakdown of all the activities to be carried out as part of the project. This table covers all the required parts of ISO 26262 – from the activity of developing the functional requirement to the safety requirements. Any additional types of reports and analyses that need to be created in sync with security requirements are also listed here. Electronic Control Units (ECU) Development Services for Body Control Modules (BCM), Powertrain, Chassis and Infotainment The objective of Section 5 Interfaces in Distributed Developments is to describe the processes and allocate the associated responsibilities within the distributed developments for items and elements. It ensures that functional safety is achieved and maintained within the supply chain, which is involved in the entire safety lifecycle, and includes six work products. ADASDevPro provides an invaluable guide to concluding the development interface agreement.

AutoSAR MCAL Development, RTE and BSW Integration, Application Layer Development, Tools Configuration and Code Generation Based on their experience in software development projects, a product development team can opt for different approaches to SDLC. A mutually agreed and agreed development interface agreement provides the customer and supplier with the information necessary to properly plan and execute the activities and work products that lead to a functionally safe end product. As simple as it may seem, there seems to be a big difference in how these agreements are presented and executed, which can lead to problems or concerns in the subsequent project. One of the most important aspects of the DIA is to identify who is responsible for carrying out the activities, approving the work products, supporting the development or execution of the activities, informing the other party of the necessary information and, if necessary, the need for consultation on the activity or work product (the well-known CISIP). The DIA should also go into detail about the expected work product and how it should be completed (if a certain format is required, an assessment will be conducted by the client or a third party, etc.). Jennifer Giangrande has worked on alternative energy projects, clean commercial vehicles and, most recently, on the functional safety of propulsion systems. Jennifer holds a BSME from Lawrence Technological University and an MSME from Oakland University. The blog covers all important aspects of safety planning management, as recommended in Part 2 of ISO 26262. Look in this section for more informative blogs about ISO 26262 and functional safety. Aspects such as defining the role, who interacts with whom, who switches to whom, etc. should be clearly mentioned in this section of the safety planning activity sheet.
However, getting the right DIA requires experience and practice. ADASDevPro offers you the advantage of their experience by generating a large number of DIA. The importance of safety planning can be measured by the fact that the entire part 2 of the ISO 26262 policy document is devoted to functional safety management and the aspects that must be included in the safety plan document. Part 2 – Section 6 of ISO 26262 recommends that, when initiating a functional safety project, an appointed project manager with a mandate to achieve certain safety objectives (as defined by ASIL) be appointed. This section is basically used to look at various work products such as test cases, HARA, FIT/gap analysis, FME (Failure Mode and Effects) analysis, safety plan, component qualification, etc. Confirmation can be made by the service providers themselves, certification bodies or consultants. The development interface agreement is part of the security plan activity. From the point of view of documentation, diademicant can be kept separately or with the document of the security plan. Analyzing the software and hardware required in the project requires due diligence.
If you look at Part 6 of the ISO 26262 documents, several tables are provided that show the methods and techniques of hardware and software analysis. The method to be chosen for this analysis is also decided on the basis of these tables. Below you will find such a table. As part of the security planning recommended by ISO 26262, several documents are created at different stages of the security lifecycle. Organization-specific rules and processes, the safety plan, the safety clearance, the functional safety assessment plan and the confirmatory measurement reports are some of the work products generated during the safety planning process. Proof of safety is the argument that provides assurance that the safety requirements of a system have been implemented at the vehicle level (referred to as an element in ISO 26262 terminology). This argument is not just a simple derivation of the products of labor. This is, in fact, a justification for why and how the available evidence achieved the Desired Level of Functional Safety (ASIL). Here are some of the issues and concerns I`ve noticed with AID in the industry: Security planning management deals with the execution and documentation of each security-related activity. We will discuss these activities in detail and see how they are carried out and documented. This closely follows the last point.
Although the client does not consider the „grey areas“ to be a cause for concern, they could most likely cause a delay or less than the successful completion of the project. For the supplier, these „grey areas“ are likely to lead to assumptions that may be wrong, resulting in unnecessary work or incorrect performance. It is the customer`s responsibility to communicate the relevant target values for the respective system or component based on the system-level targets so that the supplier achieves the target values for point and latent error measurements. If you do not communicate it correctly, it may result in vendor assumptions that may not meet the system-level requirements identified for the project. This could most likely lead to a redesign that will result in significant cost and time issues, and depending on when the discrepancy is discovered, this could lead to concerns about meeting overall functional safety requirements. .
