someone takes ownership of successNo one approach is better than all the othersWe will use the approach used in the

4. Products

Product definitionProducts composed of productsTypes of productsNeed for productsNeed for lower-level productsExamples

4. Products

1. PBDA 12

Product definition (1 of 2)

A product is something produced by nature or by human industry or art

A product is something we can procure -- hardware, software, data, services.

4. Products

1. PBDA 13

Product definition (2 of 2)Examples

Hardware -- space shuttle, house, circuit card, resistor

Software -- program, firmware Data -- documents, work products Services -- activities

The concept of a product makes explaining system engineering easier.

1. PBDA 16

Types of products (2 of 2)

4. Products

Delivered products -- part of the delivered product

Support products -- other products in support of delivered product

Either type of product may be

Hardware

1. PBDA 17

Need for products

We need products to describe what we’re controlling

Products may be developed or procured without development

4. Products

1. PBDA 18

Need for lower-level productsWe need lower-level products if we’re

going to procure something needed for doing the development

4. Products

1. PBDA 19

Good example -- We can use the lower-level products to make the higher-level product


Example 1 -- model airplane

Fuselage Wing Stabilizer Rudder Glue

4. Products

Bad example -- We wouldn’t use the lower-level products to make the higher-level product

1. PBDA 23

Definitions

Cycle -- a complete set of events occurring in the same sequence Product life cycle Contract life cycle

Phase -- part of a cycle; the period of time the activities take

Activity -- execution of a set of tasksProcess -- steps used to accomplish an

activity

The approachDetermine what customer wants

Decide what to do

Get what it takes to do it

Do it

Check it out

Convince customer it’s what he or she wanted

Make it happen

Approach consists of applying these seven activities to each product in the

7. Management by WPs

1. PBDA 37

Definition

A work product (WP) is a tangible object that is used to control the PBDA Documents Elements of environment to support

engineeringMuch of the execution of the PBDA can be

thought of as completing the associated WPs

PBDA executed by completing WPsPBDA executed by completing WPs


1. PBDA 38

Delivered productsDelivered products (2) -- product and

lower productsThe goal of PDBA is to transform lower

products into the productLower products may be

Delivered products Support products Services

Work products aid in the transformation

PBDA transforms lower products into higher productPBDA transforms lower products into higher product


1. PBDA 39

WPs for managementEnvironment (6) -- people, facilities, tools,

capital, communications, library [support products]

Control (11) -- schedule, budget, risks, TPPs, issues, AIs, timeline, plans, changes, problems, legal

Reviews and audits (9) --MR, RR, CD, PDR, CDR, TRR, VR, PCA, FCA

26 WPs support products used for managing each product in PBDA. 26 WPs support products used for managing each product in PBDA.

Optimizing WPs

Some work products can be shared between levels

Not all work products are needed at each level.

Not all WPs must always be usedNot all WPs must always be used
