WHO | WHAT | HOW


Interfacing with the user(s) and sponsor(s) and all other stakeholders in order to determine their needs.

Generating the highest level of system requirements, based on the user's needs and other constraints such as cost and

schedule.

Ensuring that this set of high level requirements is consistent, complete and correct.

Generating a set of acceptance test requirements, together with the designers, test engineers, and the user, which determine

that all of the high level requirements have been met, especially for the system-environment-interface.

Performing cost-benefit analyses to determine whether requirements are best met by manual, software, or hardware functions;

making maximum use of commercial off-the-shelf or already developed components.

Perform a partitioning to allocate all present and foreseeable requirements into discrete partitions such that a minimum of

communications is needed among partitions, and between the user and the system.

Partitioning of large systems into (successive layers of) subsystems and components each of which can be handled by a single engineer

or team of engineers or subordinate architect.

Generating products such as sketches, models, an early user guide, and prototypes to keep the user and the engineers constantly

up to date and in agreement on the system to be provided as it is evolving.

coaching the design and implementation engineers, or subordinate architects, so that any problems arising during design or

implementation can be resolved in accordance with the fundamental architectural concepts, and user needs and constraints.

Ensuring that a maximally robust architecture is developed.

Ensuring that all architectural products and products with architectural input are maintained in the most current state and never

allowed to become obsolete.

“WHAT”:

What is an architecture?

“A software architecture is the development product

that gives the highest return on investment with

respect to quality, schedule, and cost.”(Software Architecture in Practice – Bass/Clements/Kazman)

Architecture:

Blueprint, foundation, vision, coherent form or

structure, components connections and constraints,

for the system and the project developing it.

the conceptual glue(Documenting Software Architectures – Clements/Bachman/Bass/Garlan/Ivers/Little/Nord/Stafford)


“WHAT”

System Architecture: H2 document

IEEE1471:

Stakeholders have Concerns, from their Viewpoints Views

Construction business:

separate drawings per stakeholder bricklayer, electrician, plumber

Kruchten, “4+1”:

separating the different parts and put a focus per view on an

essential item:

logical view, process, development, physical, use cases

CAFCR – 5-view framework, Gerrit Muller:

Customer objectives, Application view,

Functional, Conceptual, Realization view

Agile?

What is agile and why is it important?

Changes:

Interfaces to the environment / other systems

Customer needs

Technological opportunities

Other and new markets

BDUF (– big design up front)

A lot of work at least twice…

Once for creating the full design in an early stage

Then the update of all of it due to the external changes over time

Agile/lean defer decisions to the latest possible moment


Agile Manifesto


(www.agilemanifesto.org)

4/26/2010

12 Principles behind the Agile Manifesto


1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

2. Welcome changing requirements, even late in development.

Agile processes harness change for the customer's competitive advantage.

3. Deliver working software frequently, from a couple of weeks to a couple of months,

with a preference to the shorter timescale.

4. Business people and developers must work together daily throughout the project.

5. Build projects around motivated individuals.

Give them the environment and support they need, and trust them to get the job done.

6. The most efficient and effective method of conveying information to and within a development team

is face-to-face conversation.

7. Working software is the primary measure of progress.

8. Agile processes promote sustainable development.

The sponsors, developers, and users should be able to maintain a constant pace indefinitely.

9. Continuous attention to technical excellence and good design enhances agility.

10. Simplicity--the art of maximizing the amount of work not done--is essential.

11. The best architectures, requirements, and designs emerge from self-organizing teams.

12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Create a rough initial foundation based on

the future vision and direction.

A stable and robust multi-disciplinary

system outline, inspired by customer

needs and technological opportunities,

revisited on a regular basis.

Use a time-boxed iterative approach

for detailing the requirements, fit criteria,

design models and realisation.

This is derived from the multi-disciplinary

system outline implemented

for all disciplines.

Integrating Concepts

MX21S MX21 Comment

Price $9 $12 Remarkable BOM reduction choosing MX21S for Control Panel, Wireless- and Serial Extender.

SPI 2 3 Control Panel: SPI for Touchscreen and IR-FPGA. Currently the Marvell/USI WiFi module is designed in. This module uses the SDIO interface. If in the future the Philips WiFi module would be preferred because of less power usage, then a third SPI interface is needed. That would mean that the MX21 could be used for the Control Panel from then onwards. Disadvantage is then that there are two processor types needed in stock. Extenders: SPI only for IR-FPGA.

UART 3 4 Control Panel and wireless extender need only one UART for debugging purposes. The serial extender is specified to have 4 serial ports. By multiplexing serial port 3 towards serial connection 3 and 4 the MX21S can be used. There is no requirement or use case that serial connection 3 and 4 need to be used at the same time in parallel.

MPEG4 No Yes The Control Panel should be able to display Motion JPEG pictures. This is however a different protocol than MPEG4. For now there is no requirement to be able to support MPEG2 or MPEG4 based IP-cameras.

Performance

Memory usage

Bus usage

Processor usage

Feasibility projects

1. Pronto application port to iBoard (MXL-Linux) platform

2. iBoard hardware and BSP SW platform extensions: VGA LCD, USB

3. Extender supplier selection & evaluation

4. “MyDatabase”: prototype for Editor

5. Communication with CE servers

6. CF format Extensions

7. RS232 feasibility

8. MaestroEdit project wizard

9. BoM & power calculations

10. WiFi feasibility – protocol design


What I learned

1. Early feedback from the market (end-users, installers) is essential:

• The market determines the usefullness of a product.

• Early involvement leads to buy-in.

• It is impossible to define the success of a product behind the desk!

2. Prototyping technical issues is a must:

• Separates practice from theory

• Hottest issues in our case:

• battery power usage

• wifi reliability

4/26/2010

Project Preparation Challenges

Define:

Project Plan

System Requirements

System Architecture

Effort estimations (software intensive)

Work break down

Development lead time: 6 months

Ramp-up of development teams

within one month (2 dev sites)

Feasibility, risks:

Battery power usage

Detailed calculations

Cross check with market

WiFi protocol:

TCP: not real-time, UDP: not reliable

define reliable protocol on top of UDP


What I learned

1. Don‟t invest time in detailing all req/arch before starting project market window.

2. Do invest effort in highest feasibility risks for final go/no-go of a project.

Once defined, follow all results closely during the project

3. Have experts on board, in our case: using Linux you need a guru.

4. Multiple site development: solve the communication barrier by frequent and regular

face2face meetings.

Development Challenges

Agile approach, incremental working

Requirements at start of sprint

Focus on non-functional requirements

Software: continuous integration

System: early integration slots

Technical

USB: interoperability

WIFI AP: interoperability


What I learned

1. Have a workshop at start of sprint: req / design / system interfaces / test

2. Have Continuous Integration and Test Driven Development as a standard wow.

3. Define non-functional requirements and have these tested as early as possible in the

development cycle.

4. Stop functional or feature development as soon as NFRs are below target.

5. Find multi-disciplinary integration opportunities in the earliest possible phase.

6. Never rely on standardization: external products will never comply to the standard!

You always must build in interoperability yourself!

Market Introduction and

Production Challenges

Market Introduction

Market Introduction Plan

Phased approach

Teasers

Trainings

Beta releases to selective group

Production

Testability in the factory


What I learned

1. Phased market introduction is a must to get buy-in.

2. Factory is not in sync with product development:

• Input for testability from factory point of view is a must.

• At the moment the testability requirements are needed as input, concerning

stakeholders have very different priorities (production of previous products).

3. The necessity of convincing sales in selling solutions instead of selling products.

the project is for a customer

THEN

miscommunication is the biggest risk!

Lessons learned in general

DO‟s

Incremental/iterative development with short feedback

loops

Integration as early as possible. This addresses the weak

points in architecture/design (interfaces) in an early stage.

“Vertical” integration strategy.

Testing focus on non-functional requirements as early as

possible.

Daily stand-up meetings with the team, not only during

development but in any phase of the project.

Use information radiators, sheets on the wall for

planning, status dashboard, architecture, business

backgrounds.

The customer is never wrong. Involve the customer

whenever possible and use all the feedback you can get.

Integrate over the disciplines as early as possible and as

often as possible.

Design a system from the point of view of the most

important stakeholders (decision makers for buying the

product).

DON‟Ts

Only BDUF and a lot of paper work at the start.

Give priority to functional aspects over

performance and „ilities‟.

Write documents for the shelf.

Have the process in the lead.

Communicate electronically only.

Start without an architectural foundation

especially when working on a family of products.

Postpone integration to the latest stage of the

project.

Horizontal integration: Integrate layer by layer.

Have user interfaces designed by technical

people only.
