master-plan
Master Plan is a text based project management tool that implements an algebra of projects.
These are the values propositions of master plan:
- Simplicity: keep project management into a single text file.
- Agility: embrace change, by allowing projects to specify uncertainty and allow for refinement anytime.
- Freedom: master plan is a open specification, not dependent on tools or hosting. There is this current open-source implementation, but anyone can implement tools or visualizations on top of it.
Algebra of Projects
In the algebra of projects, a project is an expression of sub-projects combined using dependency operators. These operators define how sub-projects relate to the higher-level projects in terms of execution and structural dependency, that is, in which order (if any) the sub-projects must be executed, and also whether all or some of the sub-projects must be executed at all.
At some level, sub-projects will be small enough that they don't break down further, in this case, they consist of a unit of execution.
There is also the notion cost estimation and risk. Cost may mean different things depending on the domain, but most usually it's time.
Given all these constraints and structure, master plan will build an optimum prioritization of projects and sub-projects for execution.
The entire definition of a project is defined into a single plan.txt
file
using a simple language. There are defaults for most constrains and properties
such that things can be less verbose if using the defaults.
The tool is able to build visualizations and reports from the plan file.
Ideally, the plan file should be kept in version control so that execution and planning progress can be recorded.
Commands
The mp
command line tool supports the following commands:
prioritize
- list, in order of priority, the projects ready for execution.render
- generate a report output, specified by one of the backend formats.
Syntax
Comments are preceded by hashtag (#
), and extend to the end of line
(like Shell and Python).
Everything else are definitions, in the form lrs = rhs
.
There are two kinds of definitions with respect to lrs
(left hand side):
- Definition of a project: in the form
identifier = expression
- Definition of a property of a project: in the form
identifier(identifier) = expression
. This is used to define properties of names.
A project is identified by a unique identifier. The "root" project is identified
by a special root
identifier.
Project expressions are expressions where project identifiers are combined via binary operators. Parenthesis can be used to enforce operator precedence. There are three operators:
p = a + b
- Sum:p
is executed whena
orb
is executed.p = a x b
- Product:p
is executed whena
andb
is executed.p = a > b
- Sequence:p
is executed whena
andb
is executed, in order.
Properties
Following is a list of supported properties of projects:
Property name | Expected Type | Description |
---|---|---|
name | text | title of the project |
description | text | longer description of what the project is |
url | URL | reference in the web for more context about the project |
owner | username | name of the person responsible for execution |
progress | percentage | how much progress has been made so far |
cost | number | estimated cost (aliases: "time", "estimation") |
risk | percentage | risk of failure |
Grammar
definition = project_def | predicate_def
project_def = identifier "=" expression
expression = term (("->" | "*") term)*
term = factor ("+" factor)*
factor = "(" expression ")" | identifier
predicate_def = identifier "(" identifier ")" "=" value
value = percentage | literalString
