+
+### Review Then Commit {#RTC}
+
+The vast majority of technical decisions within the Xen Project are code
+related decisions (e.g. patches and design documents), which determine whether
+a specific change can be accepted into the code base. The default decision
+making process is a review and commit process, which requires that all changes

+places: MAINTAINERS/README/CONTRIBUTING files in repositories and/or the

+- **+1** : I am happy with this proposal, but will not argue for it
+- **0** : I have no opinion
+- **-1** : I am not happy with this proposal, but will not argue against it
+- **-2** : I am not happy with this proposal, and I will argue against it
+
+A **-2** should include an alternative proposal or a detailed explanation of
+the reasons for the negative opinion. A **+2** should include reasons for the
+positive opinion.
+
+How we tally results and their implications depend on the context in which is
+is used and are marked with Passed/Failed: in one of the following sections:
+
+- [Lazy Consensus / Lazy Voting](#lazyconsensus)
+- [Leadership Team Decisions](#leadership)
+- [Project Wide Decision Making](#project-decisions)
+
+### Lazy Consensus / Lazy Voting {#lazyconsensus}
+
+Lazy Consensus is a useful technique to make decisions for specific proposals
+which are not covered by the Review Then Commit Policy or do not require a more
+formal decision (see below). Lazy Consensus is extremely useful, when you don't
+anticipate any objections, or to gauge whether there are objections to a
+proposal. The concrete process in this section is a mixture between Lazy Consensus
+and Lazy Voting and is designed to avoid unnecessary multiple stages in decision
+making.
+
+To make use of it, post something like the following on the project's
+mailing list (or some other communication channel):
+
+ > I am assuming we are agreed on X and am going to assume lazy consensus: <
+ > if there are no objections within the next seven days. <
+
+You should however ensure that all relevant stake-holders which may object are
+explicitly CC'ed, such as relevant maintainers or committers, ensure that
+**lazy consensus** is in the body of your message (this helps set up mail
+filters) and choose a reasonable time-frame. If it is unclear who the relevant
+stake-holders are, the project leadership can nominate a group of stake-holders
+to decide, or may choose to own the decision collectively and resolve it.
+
+Objections by stake-holders should be expressed using the [conventions
+above](#expressingopinion) to make disagreements easily identifiable.
+
+__Passed/Failed:__
+The proposer of Lazy Consensus decision is assumed to implicitly have an
+opinion of **+1**, unless otherwise stated.
+
+- Failed: A single **-2** by a stake-holder whose approval is necessary
+- Failed: A total sum of opinions **<=0**
+- Passed: A total sum of opinions **>0**
+
+It can only be overturned if the project leadership agrees collectively, that
+the decision is too important to be settled by lazy consensus / lazy voting.
+In situations where a proposal is failed, an alternative solution needs to be
+found, or if a decision is formally challenged, [conflict resolution mechanisms](#conflict) may need to be used to resolve the situation.
+
+__Further Examples:__
+A Lazy Consensus decision starts out with the implicit **+1** opinion of the
+proposer. If there is no explicit response, the proposal passes as the sum
+is **>0**.
+
+If there is a single **-1** without any **+** votes, the proposal fails.
+
+If there are multiple **+1**'s or **+2**'s, more **-1**'s than positive votes
+are needed for the proposal to fail. This mechanism, is often also called
+**Lazy Voting**.
+
+The process does allow for a proposer to state a starting opinion of **0** or
+**-1**. In this case, the Lazy Consensus label does not work for the process,
+as positive opinions are needed for the proposal to pass. To make use of this
+mechanism, post something like the following on the project's mailing list
+(or some other communication channel)
+
+ > I want to solicit opinions on X and am going to assume lazy voting: <
+ > My starting position is **0**, as I feel that at least one other <
+ > stake-holder should agree with the proposal. <
+ > If there is a majority in favour, without a **-2** objection within the <
+ > next seven days, I assume that the proposal holds and does not need <
+ > require further discussion. <
+
+Unlike in the lazy consensus case, a single **+1** vote is needed. Otherwise
+the proposal fails. Otherwise, the counting rules follow the general case.
+
+This can be useful in situations, where the proposer is not quite sure about
+his/her position, or where the invoker acts on behalf of the community to
+resolve a discussion which has become stuck. A starting position of **-1** can
+be used to verify that a specific approach may be a bad idea: whether this is
+really useful, has to be verified as we start using this process.
+
+### Informal Votes or Surveys
+
+Generally the Xen Project community tries to achieve consensus on most issues.
+In situations where several concrete options are possible, community members
+may organize an informal vote on the different proposals and use the
+[conventions above](#expressingopinion) to identify the strongest proposal.
+Once the strongest candidate has been identified, [lazy
+consensus](#lazyconsensus) could be used to close the discussion. In some
+situation, a specific survey may need to be created, to help identify gauging
+consensus on specific issues. For informal votes and surveys, we do not
+prescribe specific rules, as they are non-binding: it is up to the organizer of
+an informal vote or survey to interpret the result and explain it to the
+community. If the vote/survey relates to an area that is owned by the project
+leadership, the project leadership has to formally confirm the decision.
+
+Note that informal votes amongst a small set of stake-holders that disagree on
+a position during technical disagreements in code, design reviews and other
+discussions can be useful. In technical discussions it is not always clear how
+strong agreement or disagreement on a specific issue is. Using the [conventions
+above](#expressingopinion), can help differentiate between minor and major
+disagreements and reduce the time a discussions continues unnecessarily. This
+is true in particular for cases, where several maintainers may need to agree to
+a proposal.
+
+When having an informal vote or survey, they creator should consider whether
+conducting a vote or survey in public, may be divisive and damaging for the
+community. In such cases, the vote/survey should be conducted anonymously.
+
+### Leadership Team Decisions {#leadership}
+
+Each sub-project has a leadership team, which is typically made up of the most
+senior and influential developers within the sub-project (e.g. the project's
+committers). The project leadership team owns decisions, such as:
+
+- Sub-project wide policy decisions (e.g. policies, procedures and processes
+whose scope is specific to the sub-projects). This includes deviations from
+project global governance, where permissible.
+- Decisions related to sub-project assets that are not clearly owned (e.g.
+unowned code, project wide assets such as test infrastructure, etc.).
+- Decisions related to nominating and confirming leadership roles within the
+sub-project. This includes [decisions to creating and filling specialised new
+roles](#elections), such as release managers or similar, including their scope
+and set of responsibilities.
+- Resolving [conflicts](#conflict) within the sub-project that cannot
+otherwise be resolved.
+
+Leadership team decisions can be made in private (e.g. a private IRC meeting,
+on a private mailing list, through a private vote) or on a public mailing list
+using [decision making conventions](#expressingopinion). If a decision is made
+in private, the outcome must be summarized in terms of number of votes in
+favour or against on a public mailing list. Decisions should **not** generally
+be made in an anonymous vote, unless there is a good reason to do so. For
+example, if the decision may be divisive and damage the cohesion of the
+leadership team, an anonymous vote is preferred. In such cases, the leadership
+team, can ask the community manager, to arrange an anonymous vote on behalf
+of the leadership team.
+
+Decisions (also called Resolutions) require a **2/3rd** majority amongst active
+leadership team members in favour of a proposal. The tallying of votes follows
+the rules outlined below. Note that a minimum of 3 leadership team members is
+needed for a [leadership team to function](#exceptional-circumstances).
+
+Leadership team decisions normally have to be made actively: in other words
+each team member has to cast a vote **explicitly** expressing their opinion.
+The only exception are face-2-face or on-line meetings with a quorum of
+**2/3rd** of active leadership team members present at the meeting: in such
+cases a meeting chair is required who calls for decision on a resolution and
+asks for objections. This allows to conduct meetings more quickly.
+
+__Passed/Failed Resolutions:__
+
+Voting is conducted in line with the following rules:
+
+- Project leadership team members vote for (**+1**) or against (**-1**) a
+resolution. There is no differentiation between **+1**/ **+2** and
+**-1**/**-2**: in other words a **+2** is counted as a vote for, a **-2** as a
+vote against the resolution. The number of votes for and against a resolution
+is called **active vote**. **0** votes **are not counted** as an active vote.
+- A **quorum of more than 50% of active votes** is required for a resolution
+to pass. In other words, if the leadership team has 7 members, at least 4
+active votes are required for a resolution to pass.
+- The resolution passes, if a 2/3 majority of active votes is in favour of
+it.
+
+The table below maps active votes against votes needed to pass:
+
+ ---------------------------- --- -- -- -- -- -- -- -- --
+ **Active Votes** 10 9 8 7 6 5 4 3 2
+ **+1 votes needed to pass** 7 6 6 5 4 4 3 2 2
+ ---------------------------- --- -- -- -- -- -- -- -- --
+
+### Conflict Resolution {#conflict}
Sub-projects and teams hosted on Xenproject.org are not democracies but
meritocracies. In situations where there is disagreement on issues related to
-the day-to-day running of the project, Committers and Project Leads are
-expected to act as referees and make a decision on behalf of the community.
-Referees should however consider whether making a decision may be divisive and
-damaging for the community. In such cases, the committer community of the
-project can privately vote on an issue, giving the decision more weight.
+the day-to-day running of the project, the [project leadership
+team](#leadership) is expected to act as referee and make a decision on behalf
+of the community. Projects leadership teams can choose to delegate entire
+classes of conflict resolution issues to community members and/or the project
+lead (e.g. the project can choose to delegate refereeing on committer
+disagreements to the project lead; or it could choose a specific committer to
+always act as referee amongst a group of committers). Any such delegation needs
+to be approved as normal and has to be documented.
-#### Last Resort
+Should a project leadership team become dysfunctional or paralysed, the project
+leadership team or project lead should work with the community manager or
+advisory board to find a way forward.
-In some rare cases, the lazy consensus approach may lead to the community being
-paralyzed. Thus, as a last resort when consensus cannot be achieved on a
-question internal to a project, the final decision will be made by a private
-majority vote amongst the committers and project lead. If the vote is tied, the
-project lead gets an extra vote to break the tie.
+In situations where the entire Xen Project community becomes paralysed the
+impacted project leadership teams or project leads should work with the
+community manager or advisory board to find a way forward.
-For questions that affect several projects, committers and project leads of
-mature projects will hold a private majority vote. If the vote is tied, the

-Formal Votes {#formal-votes}
-------------
-
-Sometimes it is necessary to conduct formal voting within the community
-(outside of elections). Formal votes are necessary when processes and
-procedures are introduced or changed, or as part of the [Project
-Governance](#project-governance). Who is eligible to vote, depends on whether
-the scope of a process or procedure is **local** to a sub-project or team, or
-whether it affects **all sub-projects** (or in other words, is **global**).
-Examples of local scope is the [Security Policy](/security-policy.html) which

+
+### Project Wide Decision Making {#project-decisions}
+
+Project wide decisions are made through **formal global votes** and are
+conducted in rare circumstances only, following the principle of [local
+decision making](#principles). Global votes are only needed, when all sub-projects
+hosted on Xenproject.org are affected. This is true, only for:
+
+- Specific votes on creating, graduating, completing/archiving of
+sub-projects as outlined in [project governance](#project-governance).
+- Changes to this document, where sub-projects cannot specialise. In
+particular the sections: [goals](#goals), [principles](#principles), [project
+wide decision making](#project-decisions) and [project
+governance](#project-governance) (and small parts of [Xen Project wide
+roles](#roles-global), [project team roles](#roles-local) and [decision
+making](#decisions) that are needed for project governance or **apply to all
+sub-projects** as stated in those sections).
+- Changes to this document where sub-projects can specialise require at least
+one mature project other than the Hypervisor project to be impacted
+significantly by the change. The sections in question, are [project team
+roles](#roles-local) and [decision making](#decisions). These sections define
+the **gold standard** of how the original Hypervisor Project operates. In other
+cases, the Hypervisor project leadership team can agree changes to these
+sections, as they are essentially reference definitions. Other sub-projects
+have to be consulted, and have to be given time to adapt to changes.
+- Changes to existing global namespace policies (e.g. [Mailing List
+Conventions](/help/mailing-list/100-misc/139-mailing-list-conventions.html))
+and creation of new project wide namespace policies.
+- Changes to the boundary of what policies are project local and global
+decision: e.g. a decision to introduce a global Security Vulnerability Response
+Process that affects all sub-projects.
+
+Global votes are arranged by the community manager when needed (e.g. for a
+project review or a global process change). Who exactly has input on a proposal
+and can vote on it, depends on the type of change as outlined below:
+
+ -----------------------------------------------------------------------------------------
+ **Proposal** **Who reviews?** **Who votes?**
+ ----------------------------- ----------------------------- -----------------------------
+ Creating, graduating, Members of developer mailing Leadership teams of
+ completing/archiving of lists of qualifying projects **mature** sub-projects,
+ sub-projects with the exception of the
+ project which is being

+ project under review, cannot
+ vote).
+
+ Global Process Changes Members of developer mailing Leadership teams of
+ lists of qualifying projects **mature** sub-projects,

The community manager first arranges a public review, followed by a timed
private vote. Public review and voting should be open for a minimum of a week
each. For voting a traceable poll mechanism (e.g. voting form that keeps

-conventions as laid out in "Principle: Consensus Decision Making".

+auditable and tamper proof records) must be used.
+
+Voting is conducted **per project** in line with the following rules:
+
+- Each qualifying project's vote is counted per project and then aggregated
+as outlined below.
+- Project leadership team members vote for or against a proposal (there is no
+differentiation between **-1**/**-2** and **+1**/**+2**). A **0** vote is not
+counted as a valid vote.
+- A **quorum of more than 50%** of each project's leadership team members is
+required. In other words: if more than half of a project's leadership team
+members do not vote or abstain, the entire sub-project's vote is not counted.
+This avoids situations where only a minority of leadership team members votes,
+which would skew the overall result. If it becomes clear, that a sub-project is
+not likely to meet the quorum, the voting deadline can be extended by the
+community manager.
+
+__Passed/Failed Resolutions:__
+
+- If none of the qualifying projects achieve a quorum, the change cannot
+hold. In that case, we consider that there is not enough momentum behind a
+change.
+- For each qualifying project with a quorum, the percentage of votes in
+favour and against is calculated (e.g. if 5 people voted in favour, 2 against
+and 1 abstains, the share is 5/7th and 2/7th respectively).
+- Votes in favour are averaged as percentages across all projects (say we
+have per project figures of 50%, 80%, 70% in favour, then the total vote in
+favour is 66.67%).
+- If the total vote is more than 2/3rds in favour, the proposal passes.
+Otherwise it fails.
+
+Community Decisions with Funding and Legal Implications (#funding-and-legal)
+-------------------------------------------------------
+In some cases sub-project local and global decisions **may require
+input** from the [Advisory Board](#roles-ab) and/or the [Linux Foundation]
+(#roles-lf). For example, if a proposal by a project leadership team or
+a global project decision requires that the project hires a staff member or
+contractor (e.g. a PR consultant, marketing manager) or requires the funding
+of new infrastructure (e.g. additional test hardware or services) to implement
+said proposal, then funding would need to be secured from the Advisory Board or
+from other sources.
+
+If for example, a community proposal required the Linux Foundation to sign
+a legal agreement with a 3rd party on behalf of the project/sub-project, then
+of course a review of such an agreement and a signature by the Linux Foundation
+would be required.
+
+In such cases, the impacted project leadership team(s) will contact the
+Community Manager and/or Advisory Board to resolve possible issues.
