Introduction To The Delivery Process
As described in the general entry of CCU, the delivery phase is the second phase of the CCU method. In figure one the CCU method is depicted. The phases of CCU that are not covered in this article are concealed by a transparent grey rectangle.
As can be seen in figure one, the delivery phase is in between the release phase and the deployment phase. A software vendor develops and releases a software product and afterwards it has to be transported to the customer. This phase is the delivery process. This process is highly complex because the vendor often has to deal with a product which has multiple versions, variable features, dependency on external products, and different kinds of distribution options. The CCU method helps the software vendor in structuring this process.
In figure 2, the process-data diagram of the delivery phase within CCU is depicted. This way of modeling was invented by Saeki (2003). On the left side you can see the meta-process model and on the right side the meta-data model. The two models are linked to each other by the relationships visualized as doted lines. The meta-data model (right side) shows the concepts involved in the process and how the concepts are related to each other. For instance it is visible that a package consists of multiple parts, being the: software package, system description, manual, and license and management information. The numbers between the relations indicate in what quantity the concepts are related. For example the “1..1” between package and software package means that a package has to contain at least 1 software package and at the most 1 software package. So in this case a package just has to contain 1 software package. On the left side of the picture the process-data model is depicted. This consists of all the activities within the delivery process. This article is based on this process-data model. The meta-process model (left side of the process-data diagram) is divided into several parts which are presented along with the corresponding paragraphs throughout the article to make it easier to understand.
The tables that describe the concepts of the meta-data model and the activities of the process-data model are presented beneath figure 2.

Famous quotes containing the words introduction to the, introduction to, introduction, delivery and/or process:
“Such is oftenest the young man’s introduction to the forest, and the most original part of himself. He goes thither at first as a hunter and fisher, until at last, if he has the seeds of a better life in him, he distinguishes his proper objects, as a poet or naturalist it may be, and leaves the gun and fish-pole behind. The mass of men are still and always young in this respect.”
—Henry David Thoreau (1817–1862)
“We used chamber-pots a good deal.... My mother ... loved to repeat: “When did the queen reign over China?” This whimsical and harmless scatological pun was my first introduction to the wonderful world of verbal transformations, and also a first perception that a joke need not be funny to give pleasure.”
—Angela Carter (1940–1992)
“For the introduction of a new kind of music must be shunned as imperiling the whole state; since styles of music are never disturbed without affecting the most important political institutions.”
—Plato (c. 427–347 B.C.)
“There was no speculation so promising, or at the same time so praisworthy, as the United Metropolitan Improved Hot Muffin and Crumpet Baking and Punctual Delivery Company.”
—Charles Dickens (1812–1870)
“Healthy parenting is nothing if not a process of empowerment. As we help to raise our children’s self-esteem, we also increase their personal power. When we encourage them to be confident, self-reliant, self-directed, and responsible individuals, we are giving them power.”
—Louise Hart (20th century)
