Entreprise Solutions Delivery

Question 1

What is Entreprise Solutions Delivery?

Answer 1

The application of Lean-Agile principles and practices to the specification, development, deployment, operation and evolution of the world’s largest and most sophisticated applications, networks and systems.

Question 2

What are the 3 dimensions of Entreprise Solutions Delivery

Answer 2

Lean System and Solution Engineering
Coordinating Trains and Suppliers
Continually Evolve Live Systems

Question 3

Which practices compose Lean Systems and Solution Engineering?

Answer 3

Continually refine the fixed/variable Solution intent
Apply multiple planning horizons
Architect for scale, modularity, releasability and serviceability
Continually address compliance concerns

Question 4

Which practices compose Coordinating Trains and Suppliers

Answer 4

Build and integrate solution components and capabilities with ARTs and Solution Trains
Apply continuish integration
Manage the supply chain with systems of systems thinking

Question 5

Which practices compose Continually Evolve Live Systems

Answer 5

Build a Continuous Delivery Pipeline

Evolve deployed systems

Question 6

Continually refine the fixed/variable Solution intent ?

Answer 6

It replaces the traditional V model with continuous and concurrent engineering

Question 7

What continuous and concurrent engineering allow?

Answer 7

to align all system builders to a shared direction.

Question 8

What do Agile teams and trains use to manage and forecast work

Answer 8

Backlogs and roadmaps

Question 9

What do roadmaps provide?

Answer 9

It provides multiple planning horizons. Engineers forecast long-term works but commit to near-term work.

Question 10

What architecture should achieve?

Answer 10

Create a resilient system that enables teams and trains to independently build, test, deploy—and even release—their parts of large solutions.

Question 11

What does a Lean QMS achieves?

Answer 11

It makes compliance activities part of the regular flow

Question 12

How many people in an ART?

Answer 12

50-125

Question 13

How do trains work ?

Answer 13

Trains align everyone on a regular cadence. Integration is done at least at every PI.

Question 14

Which reasons make large systems difficult to continuously integrate

Answer 14

Long lead-time items may not be available
Integration spans organizational boundaries
Automation is rarely end-to-end
The laws of physics dictate certain limits

Question 15

What is the goal of “continuish integration”

Answer 15

Frequent partial integration with at least one full solution integration each PI

Question 16

What does the supplier Product Manager and Architect do

Answer 16

He continuously align the backlog, roadmap, and Architectural Runway with those of the overall solutions

Question 17

What is “Clone-and-own”?

Answer 17

A supply chain coordination pattern.

Question 18

What are advantages and disadvantages of Clone-and-own=

Answer 18

It speeds up execution but prevents economy of scale often raising costs and lowering quality.

Question 19

What is an alternative to Clone -and-own?

Answer 19

The platform approach. It places all builders on one value stream with aligned roadmaps

Question 20

What is enterprise solution delivery about?

Answer 20

Apply lean system engineering to build really big systems
Coordinate and align the full supply chain
Continually evolve live systems
