+# Development Cycle
+
+Development of Open MCT Web occurs on an iterative cycle of
+sprints and releases.
+
+* A _sprint_ is three weeks in duration, and represents a
+  set of improvements that can be completed and tested by the
+  development team. Software at the end of the sprint is
+  "semi-stable"; it will have undergone reduced testing and may carry
+  defects or usability issues of lower severity, particularly if
+  there are workarounds.
+* A _release_ occurs every four sprints. Releases are stable, and
+  will have undergone full acceptance testing to ensure that the
+  software behaves correctly and usably.
+
+## Roles
+
+The sprint process assumes the presence of a __project manager.__
+The project manager is responsible for
+making tactical decisions about what development work will be
+performed, and for coordinating with stakeholders to arrive at
+higher-level strategic decisions about desired functionality
+and characteristics of the software, major external milestones,
+and so forth.
+
+In the absence of a dedicated project manager, this role may be rotated
+among members of the development team on a per-sprint basis.
+
+Responsibilities of the project manager including:
+
+* Maintaining (with agreement of stakeholders) a "road map" of work
+  planned for future releases/sprints; this should be higher-level,
+  usually expressed as "themes",
+  with just enough specificity to gauge feasibility of plans,
+  relate work back to milestones, and identify longer-term
+  dependencies.
+* Determining (with assistance from the rest of the team) which
+  issues to work on in a given sprint and how they shall be
+  assigned.
+* Pre-planning subsequent sprints to ensure that all members of the
+  team always have a clear direction.
+* Scheduling and/or ensuring adherence to
+  [process points](#process-points).
+* Responding to changes within the sprint (shifting priorities,
+  new issues) and re-allocating work for the sprint as needed.
+
+## Sprint Calendar
+
+Certain [process points](#process-points) are regularly scheduled in
+the sprint cycle.
+
+### Sprints by Release
+
+Allocation of work among sprints should be planned relative to release
+goals and milestones. As a general guideline, higher-risk work (large
+new features which may carry new defects, major refactoring, design
+changes with uncertain effects on usability) should be allocated to
+earlier sprints, allowing for time in later sprints to ensure stability.
+
+| Sprint | Focus                                                   |
+|:------:|:--------------------------------------------------------|
+| __1__  | Prototyping, design, experimentation.                   |
+| __2__  | New features, refinements, enhancements.                |
+| __3__  | Feature completion, low-risk enhancements, bug fixing.  |
+| __4__  | Stability & quality assurance.                          |
+
+### Sprints 1-3
+
+The first three sprints of a release are primarily centered around
+development work, with regular acceptance testing in the third
+week. During this third week, the top priority should be passing
+acceptance testing (e.g. by resolving any blockers found); any
+resources not needed for this effort should be used to begin work
+for the subsequent sprint.
+
+| Week  | Mon                       | Tue    | Wed | Thu                          | Fri         |
+|:-----:|:-------------------------:|:------:|:---:|:----------------------------:|:-----------:|
+| __1__ | Sprint plan               | Tag-up |     |                              |             |
+| __2__ |                           | Tag-up |     |                              | Code freeze |
+| __3__ | Sprint acceptance testing | Triage |     | _Sprint acceptance testing*_ | Ship        |
+
+&ast; If necessary.
+
+### Sprint 4
+
+The software must be stable at the end of the fourth sprint; because of
+this, the fourth sprint is scheduled differently, with a heightened
+emphasis on testing.
+
+| Week   | Mon                       | Tue    | Wed | Thu                          | Fri         |
+|-------:|:-------------------------:|:------:|:---:|:----------------------------:|:-----------:|
+| __1__  | Sprint plan               | Tag-up |     |                              | Code freeze |
+| __2__  | Acceptance testing        | Triage |     |                              |             |
+| __3__  | _Acceptance testing*_     | Triage |     | _Acceptance testing*_        | Ship        |
+
+&ast; If necessary.
+
+## Process Points
+
+* __Sprint plan.__ Project manager allocates issues based on
+  theme(s) for sprint, then reviews with team. Each team member
+  should have roughly two weeks of work allocated (to allow time
+  in the third week for testing of work completed.)
+  * Project manager should also sketch out subsequent sprint so
+    that team may begin work for that sprint during the
+    third week, since testing and blocker resolution is unlikely
+    to require all available resources.
+* __Tag-up.__ Check in and status update among development team.
+  May amend plan for sprint as-needed.
+* __Code freeze.__ Any new work from this sprint
+  (features, bug fixes, enhancements) must be integrated by the
+  end of the second week of the sprint. After code freeze
+  (and until the end of the sprint) the only changes that should be
+  merged into the master branch should directly address issues
+  needed to pass acceptance testing.
+* __Acceptance Testing.__ Structured testing with predefined
+  success criteria. No release should ship without passing
+  acceptance tests. Time is allocated in each sprint for subsequent
+  rounds of acceptance testing if issues are identified during a
+  prior round. Specific details of acceptance testing need to be
+  agreed-upon with relevant stakeholders and delivery recipients,
+  and should be flexible enough to allow changes to plans
+  (e.g. deferring delivery of some feature in order to ensure
+  stability of other features.) Baseline testing includes:
+  * __Testathon.__ Multi-user testing, involving as many users as
+    is feasible, plus development team. Open-ended; should verify
+    completed work from this sprint, test exploratorily for
+    regressions, et cetera.
+  * __24-Hour Test.__ A test to verify that the software remains
+    stable after running for longer durations. May include some
+    combination of automated testing and user verification (e.g.
+    checking to verify that software remains subjectively
+    responsive at conclusion of test.)
+  * __Automated Testing.__ Automated testing integrated into the
+    build. (These tests are verified to pass more often than once
+    per sprint, as they run before any merge to master, but still
+    play an important role in acceptance testing.)
+* __Sprint Acceptance Testing.__ Subset of Acceptance Testing
+  which should be performed before shipping at the end of any
+  sprint. Time is allocated for a second round of
+  Sprint Acceptance Testing if the first round is not passed.
+* __Triage.__ Team reviews issues from acceptance testing and uses
+  success criteria to determine whether or not they should block
+  release, then formulates a plan to address these issues before
+  the next round of acceptance testing. Focus here should be on
+  ensuring software passes that testing in order to ship on time;
+  may prefer to disable malfunctioning components and fix them
+  in a subsequent sprint, for example.
+* __Ship.__ Tag a code snapshot that has passed acceptance
+  testing and deploy that version. (Only true if acceptance
+  testing has passed by this point; if acceptance testing has not
+  been passed, will need to make ad hoc decisions with stakeholders,
+  e.g. "extend the sprint" or "defer shipment until end of next
+  sprint.")
