projectdoc Toolbox

Document a decision for an option. This is useful to state the reasons and the options that have been evaluated. Later other team members will have it easier to understand the decision.

Documentation Type


The document type decision provides the following properties:


Please note that only information about specific properties is provided here. Common document property used by all document types are documented by Document Properties.


Group decisions by their type. A project may provide its own set of types via the Decision Type Doctype.


List the stakeholders that take special interest in this decision and therefore support the effort put into this.



Give a short summary about what has been decided. Add anything that is of interest for users having a brief look at this document.


Define the problem for which a decision has been made by the team. The problem has these subsections:


Define the problem that this decision solves.


Provide details why this is relevant for the project and why it should be documented to be referable later.


Provide details what implications this decision has on the project.

Problem Constraints

Document constraints on the problem that influence the decision. These constraints are described in the following subsections:


Illustrate the functional and non-functional-requirements that constrain the decision.


Provide details what other drivers are relevant for the decision.


Provide details which risks are involved for the decision.


Decisions have to be made in situations where not every information detail is available. Otherwise the path to take would be clear without any doubts. To close the gaps between known and unknown assumptions have to be made. This section allows to document the assumption so that the decision is better understandable later.


Provide details which assumptions have been made to make the decision. It is assumed that assumptions cannot be proven else this would be a requirement or not mentioned if proven invalid.

Check Assumptions

Describe strategies how the given assumptions can be proofed or refuted?


List the risks you assume this assumption has.


Provide a list of alternatives that have or have not been examined.


Provide information about the decision that has been made.


Define what has been decided to do. This should be a brief statement since this is also rendered in the index document.


State what reasons led to the decision.


Provide details what implications this decision has on the project.


Specify the date of the decision.


Provide a list of stakeholders that made the decision. If there is uncertainty about why this decision has been made, these stakeholders may provide additional information at a later time. Consider then to include this information in this document.

Subordinate Decisions

Add decisions to this decision as child documents if these decisions are in a close relationship.


These are internal notes that are usually not exported and only visible to team members with write access.

But this is not a safe place to store sensible information. It is just a convenience for the reader to not be bothered with notes stored here for the authors for later use. The security level is about suppressing the representation by a CSS style. Therefore consider this as a convenience for the reader, not as a security tool.


The text of notes sections is also indexed.


For a document the references section contains pointers to resources that prove the statements of the document.

Often these proofs are not easily distinguishable from further information. In this case you may want to skip the reference section in favour for the resource list.


For further information please refer to References and Resources.


The resources section provides references to further information to the topic of the document.

This may be information on the internet provided by the resource or information in the team's information systems. Anything the reader of the resource might want to know, may be listed here.
