Microsoft Excel or Microsoft Project?
Why Microsoft Office Project 2007 is Easier and
More Effective for Managing Projects
Summary:
Using the right tool gives project managers a distinct advantage when developing plans,
schedules and communicating project status. This whitepaper outlines the advantages of
using Microsoft Project 20007 instead of Microsoft Excel in project planning, scheduling and
management. Microsoft Office Project 2007 is designed to help manage key project
components using integrated planning, tracking, analyzing, and communicating tools.
Microsoft Project 2007 is an enabling tool for project managers designed specifically to
increase effectiveness and productivity around managing project type activities. While
Microsoft Office Excel is an exceptionally powerful tool, it is designed more to support the
creation, formatting and communication of spreadsheet type information.
Introduction
An important first-step in managing a project
and ensuring its success is to understand every
project‟s Triple Constraint (Scope, Cost, and
Time). Managing these constraints can mean the
difference between success and failure. In fact
the 2004 Standish Groups “Chaos Report” found
that
53% (of Projects) are challenged (late, over
budget and/or with less than the required
features and functions).
Monitoring the triple constraint is straight-
forward using Microsoft Project 2007. The
program is designed to automatically calculate
and then recalculate the project plan based on
new or revised information about scope, time,
and resources. Making those forecasts clear to
stakeholders is key. With Project 2007, it is easy
to graphically represent current plans and any
changes so that managers and team members can effectively take appropriate action.
Many managers use Microsoft Excel to manage project information such as
scheduling project dates or recording task assignments and not knowing when to
shift to using Microsoft Project 2007. A big reason for this is one of familiarity with
the right tools for the job and understanding when to shift from one tool to another.
When it comes to managing project information such as scope (phases, tasks,
milestones, deliverables), timelines (schedules, deadlines) and resources
(assignments, effort, availability, costs) it is time to shift from Excel to Project.
Project is specifically designed with easy to use and powerful tools to help ensure
 your success on managing any type of project, big or small. Once familiar with
Project 2007, using Excel to manage project information simply does not make sense
since Project 2007 is set-up to increase your productivity and effectiveness
immediately. Key challenges in using Excel include:

Project and summary level data calculation is largely done manually.

Creating and maintaining phases, tasks, and milestones is more difficult.

Creating and maintaining project timelines & deadlines is not dynamic or easy.

Assigning resources and costs to tasks is not automated nor project specific

There are no automatic updates for scope, time or resource assignments.

There are no specific tools to manage change effectively.

Difficult to see the ripple effect of delays.

There is no feature that calculates the impact of resource availability.

There are no pre-defined project specific reports for different stakeholders.
Building a Project Schedule
Microsoft Project enables Project Managers, not to simply create a schedule but to see a
project through the life cycle of planning, tracking and reporting. Also, if you happen to
have a plan in Microsoft Excel, importing it to Microsoft Project is simplified by using the
Microsoft Project step-by-
step guides to map
Microsoft Excel columns to
project columns. It is then
possible to convert the
task list from Microsoft
Excel into phases, tasks
and milestones which
defines the project scope
known as the work
breakdown structure
(WBS). Microsoft Project
2007 has the necessary
and easy to use tools to
quickly set-up and
maintain your WBS. The
next step is to establish a
timeline by defining task
durations and
dependencies or links.
Completing the schedule
involves identifying and
allocating resources. Once complete, the task relationships can be represented in the form
of graphs or reports. Information can then be easily shared.
Some of the key tools Microsoft Project can do for you that Microsoft Excel cannot include:

Quickly set up project phases, tasks and milestones

Easily define task durations and relationships

Clearly identify and allocate resources and coordinate workload

Quickly access and share relevant project information

Effortlessly create custom reports to keep the project team informed and aligned
With Microsoft Project it is also possible to:

Import existing data from Microsoft Excel or Outlook.

Initiate a plan using the built-in project templates.

Collapse or expand plans to show the necessary level of detail.

Click and drag to change task duration.

Keep notes on important task information.

Do “what if” analysis with multiple undo‟s.

Focus on tasks that are driving your project completion and critical path.

Determine the factors that are affecting task dates and easily trace the
source of issues.
In addition to importing Microsoft Excel files, Microsoft Project offers users two options to
create/start a new
project. First, project
schedules can be
created from
templates. In addition
to Microsoft Project‟s
built-in templates and
those available at
Office Online, custom
templates can be built.
Using templates saves
time and ensures
consistency &
standardization across
an organization.
The second approach is
to build a plan from
scratch using the
powerful planning tools
Microsoft Project 2007 has to offer. To build dynamic and effective plans in Microsoft
Project follow these five steps:
1.
Enter WBS (phases, tasks and milestones) into task name column.
2.
Outline (indent/outdent) tasks to reflect WBS hierarchy (major, minor and task
pieces).
3.
Estimate duration (or work-for-work based schedules).
4.
Set dependencies or task links to establish the flow of activities.
5.
Assign resources (and costs if applicable).
Unlike in Microsoft Excel, any task with zero duration in Microsoft Project appears as a
milestone automatically. A milestone is a reference point marking a major event in a project,
used to monitor the project's progress. By default, milestones appear as diamonds on the
Gantt chart, as shown in the above example at the end of each phase (summary task).
There are many different models and methods for estimating duration, but none is entirely
accurate. In Microsoft Excel, it would be necessary to build formulas to see a project‟s total
duration or the total duration per phase or major pieces. Using Microsoft Project, a user can
establish a base calendar and estimate each task by entering its duration in the task
column. In turn, Microsoft Project will total the project and phase duration, without having
to build in formulas.
In Microsoft Project it is possible to easily create task dependencies, which are also referred
to as activity relationships or task connections. Types of dependencies that can be
established include sequential (finish to start), concurrent, and overlapping. Once the task
relationships are established in conjunction with duration estimates, Microsoft Project 2007
automatically calculates your schedule. Furthermore it establishes a dynamic schedule that
can be recalculated automatically as you modify your plan. One extraordinary new tool in
Project 2007 is „Show Change Highlighting‟ which will highlight the impact of making a change
throughout the entire plan so you can decide whether to keep or undo the change. It will also
calculate the critical path which can be easily viewed through filters, highlights, groups or
formatting. In Microsoft Excel this would involve many separate and complicated
calculations to determine the overall schedule a critical path.
So what is Critical Path? It is the set of tasks that affects the overall end date. In any
single-project network, one sequence of tasks fixes the duration of the project. Any slippage
or failure to begin a task on time that is on the critical path will cause the project to finish
later than planned. The critical path is illustrated here using the red highlights and the red
Gantt bars.
Microsoft Project allows users to manage cost and resources by defining local project
resources and the respective related information in a separate view or window. In turn, the
Microsoft Project Resource Assignment Tool is used to add resources to tasks, including
multiple resources to a single task or multiple resources to multiple tasks. This is a
cumbersome process in Microsoft Excel involving creating and linking worksheets.
Communicating from the Project Schedule
Microsoft Project has capabilities and features beyond those available in Microsoft Excel.
Those features can be used to present project data to different stakeholders according to
their requirements. It is easy to keep stakeholders informed using these Microsoft Project
capabilities:

Using appropriate views to keep different stakeholders informed

Controlling the information to present with predefined tables

Focusing on the specific information using filters

Grouping information for effective communication and decision making

Highlighting cells to convey a different meaning

Analyzing and reporting project data in professional reports and charts
Using Microsoft Excel, it would take numerous steps to generate the views that are one click
away in Microsoft Project. There are many built-in views in Microsoft Project and it is
possible to create custom views as well. Some of the views include:
