当老板询问您项目和原始计划相比有何进展时,您最不应当说的是“我不知道”。 在项目滚动之前,可以通过设置基线并保存为原始日程的快照来避免这种情况。

如果当前数据似乎从未与基线同步,可能需要仔细查看原始计划。 例如,项目范围可能已更改,或者你所需的资源可能超出最初的想法。 检查项目 利益干系人 ,并考虑使用上述过程设置新的基线。

设置基线后向项目添加任务并更新基线

新增任务并链接任务

通过增加工时的方式压缩任务工期

加班工时会分摊在工作日的工时中,并体现在单个任务“工期”的缩短上。(工时增加,工期减少)

工作日的加班,应体现在单个任务的“实际开始时间”、“实际完成时间”和任务条形图上。(工期减少,任务条形图长度变短)
非工作日的加班,应体现在单个任务的“实际开始时间”、“实际完成时间”和任务条形图上。(工期减少,任务条形图长度未变化或变长(周末两天))

项目计划完成时间:7月25日
项目计划压缩工期:1个工作日


加班计划:任务3安排周六加班1个工作日


如果加班是因为应对任务的逾期风险而实施的,加班后按时完成的,则不体现在加班工时上。加班后仍未按时完成的(实际逾期),体现在任务“实际完成时间”上。

单个任务需要分阶段执行时的任务分拆设置

适用于任务在开始执行并首次更新进度后存在暂停执行后继续执行的情况。

基线开始时间:6月27日
基线完成时间:7月5日
工期:7个工作日
实际开始时间:6月27日
当前任务进度:20%

该任务在7月28日起暂停执行,执行任务分拆操作。(工期不变,任务进度百分比按实际比例可能跨拆分后任务条形图)


该任务再次开始执行时,应拖动剩余部分任务条形图至实际开始日期(6月30日)处,已反映后续任务的实际开始时间。(工期不变)


拖动剩余部分任务条形图中进度条形图未覆盖部分至实际开始日期(6月30日)处。(工期改变)

已设置基线的已开始任务在变更基线后的影响

设置基线
基线开始时间:7月5日
基线完成时间:7月11日
工期:5个工作日

设置基线后更新任务
实际开始时间:6月28日
完成百分比:30%

变更基线后(计划变更后再次设置基线)
基线开始时间:6月28日(取自任务当前“开始时间”)
基线完成时间:7月11日(任务当前未完成,即未设置实际完成时间,该基线完成时间取自当前“完成时间”)

工期:5个工作日(不变)

整体变化:

1,当前基线条形图变长。
2,当前任务条形图以设置新基线的时间点为界被截断,分别对齐当前”开始时间“和当前”完成时间“。

系统环境为Fedora 35版本,当采用Fedora 36版本时,会因openssl 3.0导致make时产生兼容性提示信息。

[root@compiler httpd-2.4.53]# ./configure --help
`configure' configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX

  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/apache2/bin', `/usr/local/apache2/lib' etc.  You can specify
an installation prefix other than `/usr/local/apache2' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory 
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
