Example 2: Term „Process“ - 3 levels of abstraction (ASPICE 3.0)

Models for Process Assessment Abstraction from

Methods Abstraction from

Team

The “WHAT” (the goals): [what is to be done, why, and what are the technical dependencies] The “HOW” (the way to reach the goals): [methods, tools, templates, metrics, roles & skill definitions, when to do all this on logical timeline to form specific workflows including process tailoring guidance etc.] The “DOING”: [tailoring, set-up and project performance according to the tailored method] 8

SPICE 

Agile 

Wrong Understanding: „Agile means quick and dirty“ „Don´t think, just follow the process“ 10

Functional Safety (ISO 26262)

„I won‘t use agile methods if I can get in jail for doings so! "

ISO26262!

Source: ISO/FDIS 26262-2 – BL18

13

Example 1: V-Model Development

The system development process is based on the concept of a V-model […] Source: ISO 26262-2:2011(E)

•

V-Model does not mean Waterfall

•

Iterations are foreseen in the ISO26262

 No contradiction to agile development here

14

Example 2: Safety roles in agile?

New role

Existing role with new skills (Safety Auditor and Project Safety Manager)

As the term “safety manager” is defined as a role (see ISO 26262-1), its assignment can be split between different persons in a matrix organization. Source: ISO 26262-2:2011(E)

• •

However, the Team role in Scrum will not be sufficient Often used terms in agile: • T-Shaped Engineer

15

Example 3: Upfront Planning

The planning of a safety activity shall include describing: a) the objective; b) the dependencies on other activities or information; c) the resource responsible for performing the activity; d) the required resources for performing the activity; Source: ISO 26262-2:2011(E) e) the starting point in time and duration; and (original not highlighted)  Classic project planning  Maybe mitigated by defined iterations and regular activities within the iterations. But still doesn‘t fit well. BTW: In agile we have persons. Not resources. 16

Agile vs. ISO 26262

ISO26262!

Agile?

Craftsmanship helps to get the balance

17

System Development

„Agile works for software development, but we create systems here!"

System!

Agile!

19

Typical System Topics

Prepare Production

Release Planning

System Validation (e.g. durability tests)

System Integration

HW-SW-Mechanic Interfaces

Development

Supplier Selection -

Purchasing and Supplier Mgmt. 20

Example 1: Supplier Selection Traditional: Technology Evaluation

Technology Selection

Supplier Evaluation

Supplier Selection

 Late interaction with purchasing  Information gets lost between Development and Purchasing  Often time pressure More agile:

Technology Evaluation

Supplier Evaluation

Technology Selection

Supplier Selection

 Purchasing is involved in the earlier phases  Establish working interaction with supplier 21

Example 2: System Validation

• Several types of tests can not be performed iteratively • Durability Tests (lifetime tests) • Test drives on specific tracks • Production tests + Suitable Tools and Processes need to be in place + Good Test Documentation is required Some mitigations:  Early test design „Test first“  High Interaction / communication between development and test  Test simulation and automation where possible

Agile and System Development

System?

Agile?

23

What else?

Large Scale Organizations

Top Management Sales, Marketing,… …

Product Management

Development

Remote Development

• Hierarchies, Command and Control • Politics (incl. Budget and Resource Fights)

Research

25

Being a supplier

Fixed Quality?

Fixed Quality „Quality is a standard, not a variable“

vs.

Traditional

Fixed Time

Fixed Functions

Flexible Time

Change requests after the last responsible moment Unpredictable interaction and escalations Short term requests directly to developers

Agile

or

Flexible Functions

Decide at the last responsible moment

vs.

Frequent and early interaction Discipline (e.g. undisturbed sprints, SPOC,..)

26

Culture: Schneider Culture Model „We succeed by working together“

Reality oriented

Diversity

CONTROL Predictability

COLLABORATION

Process Stability Order

People Affiliation People oriented

„We succeed by getting and keeping control“

Partnership

„We succeed by growing people who fulfil our vision“

Hierarchical Standardization Security Power

Company oriented

„We succeed by being the best“

COMPETENCE Dedication

CULTIVATION

Craftsmanship Possibility oriented

Be the Best Expertise
