What are possible motivations for Systems Engineering?
SE is an interdisciplinary approach and means to enable the realisation of complex technical systems
- people rely on complex, technical Systems every day
- daily business in logistics and transportation
- new possibilities
(moon landing, exploration of oceans) - steady increase of requirements
- CPS (Cyber Physical Systems) lead to higher complexity and number of interfaces
What are the challenges of product development?
- No consistent understanding of the overall system
- Component orientated thinking
- Specific models used in each dicziplin
- No transparency
- Late integration of production constrain
- Non-methodical approach
Problems:
- Late and expensive changes
- Subsequent need for changes
- Long development duration
- quality problems
- high warrenty and goodwill costs
- high communication effort
Why do we need 'Systems engineering'?
- Increasing product complexity
- Increased competition
- Multi-Project Management
- Increasing organisational complexity
- Specialisation of engineering domains
- Increasing technilogical complexity
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
Definition of SE of the Research Group Product Creation
Systems Engineering is a structured, multi-discipline approach for the development of complex technical Systems to reach a interdisciplinary optimum in a before defined time and cost frame.
- Overall disciplines reaching optimum
- Safety and reliability
- Handling of complexity
- Point of view: User
- Reduction of life-cycle time
- Cost reduction
Describe the Stakeholder Analysis according to Freemann.
- Stakeholder's collection (Stakeholder Mapping)
- Stakeholder's meaning (Stakeholder Behavior Analysis)
- Stakeholder's goals (Stakeholder Behavior Explanation)
- Stakeholder's behavior patterns (Coalition Analysis)
- Expansion of the strategic management approach to the company environment
- Systematic recording of every stakeholder in a company
- Evaluation of the stakeholder relating to the influence potential
- Anticipation of behavior patterns
- Goal: Security and increase of the company‘s achievements

What is the purpose of the Design Definition Process? And what makes a system design?
Provide sufficient detailed data and information about the system and its elements -> enable the implementation consistent with architectural entities
System Design…
supplements the system architecture providing information and data useful and necessary for implementation of the system elements.
…is the process of developing, expressing, documenting and communicating the realization of the architecture of the system through a complete set of design characteristics described in a form suitable for implementation.
Explain the difference of the architecture definition versus the design definition. (Use 3 arguments)
1.
- The architecture definition process focuses on the understanding and resolution of the stakeholder concerns.
- The design definition process is driven by specified requirements, the architecture, and more detailed analysis of performance and feasibility
- Architecture focuses on suitability, viability, and adaptability over the life cycle.
- Design definition addresses the implementation technologies and their assimilation.
- Architecture focuses more on the „what“ than the „how“.
- Design provides the „how“ or „implement-to“ level of the definition.
Name and explain different verification concepts!
examination against applicable documentation (Confirmation of requirements, properties)
Example: Color, Weight, Dimensions
Analysis:
Analytical data or simulations (theoretical compliance)
Used if not possible or too expensive
Example: FEM
Demonstration:
Qualitative exhibition of functional performance
Example: Average battery life
Certification:
Written assurance with legal or industrial standarts
Example: CE / ISO
Test:
Function of interest is tested under controlled conditions
What is the aim of the Life Cycle Model Management Process?
Establish and maintain policies and procedures to support the organization's ability to acquire and supply products and services
Provides life-cycle integrated system models to meet the organization‘s strategic plans, policies, goals, and objectives for all projects and system life cycle stages.
What is the 'SEMP –Systems Engineering Management Plan'?
...includes all project plans and activities (from concept to disposal)
...defines what and how activities are executed
...defines how the effort will be managed (responsiblilities... risk management)
Why do we need tailoring? And what Tailoring levels are there?
- Tailoring enables use of SE
- Experience and Best practices are necessary
External standard
(e.g. INCOSE Handbook) -->
Organizational Level (company) -->
Project Level (SOI)
Sketch the V Model from DoT
SE Management - Risk Management. Draw a model of Risk Management Activities over the Project Phases.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
