Nearly 70 percent of IT projects are dogged by cost-overruns or aren't completed on schedule due to poor planning, poor communication or poor resource allocation. This story assess the impact of the 14 most common project management mistakes and offers ways IT groups can avoid them 

It's no wonder only 29 percent of IT projects are completed successfully, according to The Standish Group. Project management consultants and software providers say they see IT departments making the same project management mistakes over and over:

IT groups don't follow standard project management processes.

They don't have the right staff working on projects.

They don't assess the risks that could imperil their projects or determine ways to mitigate those risks.

The following list of the 14 most common project management mistakes ought to help you pinpoint where your projects are going wrong and measures you can take to improve them. The upside of avoiding these most common project management pitfalls is tremendous. Not only will your project success rate increase, you'll also improve satisfaction among internal customers, IT's stock inside the organization will increase in value, and the business will benefit from systems that make them more competitive that get delivered on time and on budget.

Staffing Mistakes

Mistake No. 1: Projects lack the right resources with the right skills.

Impact: Proper project staffing is critical, yet improperly allocating resources tops the list of most common project management mistakes. Not having the right people on a project can kill it.

Solution: IT and project managers need full visibility into the skills and workloads of all of their resources, including consultants, contractors and outsourcers, who often get left out of skills assessments even though they're doing a "huge" proportion of work. Projectmanagement software can provide such visibility into everyone's skills and workloads.

Once IT and project managers know who's doing what, they have to figure out how to allocate resources across myriad projects and day-to-day work.

Mistake No. 2: Projects lack experienced project managers.

Impact: Projects can quickly grow out of control without a savvy project manager at the helm.

Solution: Hire project managers with certifications and the finesse required to manage stakeholders. Good project managers have to have strong soft skills. They need to know how to facilitate meetings, manage risk and handle a variety of different stakeholders—the business people who are looking for functionality, the IT people who care about security, and the financial people who are worried about the budget.

Process Mistakes

Mistake No. 3: IT doesn't follow a standard, repeatable project management process.

Impact: This is the second of the most common project management mistakes. Lack of methodology increases the risk that tasks related to the project will fall through the cracks, that projects will have to be re-worked, and ultimately that a project won't be completed on time or on budget.

Solution: A project management methodology helps you tackle projects efficiently and makes you aware of all the activities involved in the execution of a project as PMP Methodology.

Mistake No. 4: IT gets hamstrung by too much process.

Impact: Too much process makes the project team inflexible, and their inflexibility frustrates stakeholders.

Solution: Be flexible and communicate with project sponsors and stakeholders.

Mistake No. 5: They don't track changes to the scope of the project.

Implication: The budget for the project explodes. So does the timeline.

Solution: Following a formal change request process: The individual requesting the change in scope (e.g. additional features or functionality) needs to explain the specific changes on a change-in-scope document, and the project manager needs to determine how that request will impact the budget and timeline. The project sponsor has to sign off on the change-in-scope request.

Mistake No. 6: They lack up-to-date data about the status of projects.

Impact: You can't manage what you can't measure.

Solution: Software.

Mistake No. 7: They ignore problems.

Impact: Problems don't solve themselves. They fester the longer you ignore them and ultimately compound the cost of the project.

Solution: "If you do something wrong, it's about how well you fix it"

Planning Mistakes

Mistake No. 8: They don't take the time to define the scope of a project.

Impact: If a project's scope isn't well-defined by the business and IT up front, the project can end up ballooning like Friends actor Matthew Perry in the sitcom's later seasons. What's more, IT lacks the clarity and direction it needs to complete the project on time and on budget and meet the business's expectations.

Solution: Ill-defined projects are best served by a business case and a scoping exercise.

Mistake No. 9: They fail to see the dependencies between projects.

Impact: Projects don't happen in isolation. They're often dependant on other projects going on at the same time. When project managers fail to see the dependencies between projects

Solution: Take dependencies into account during project planning, Talking with stakeholders and diagramming the project can help uncover dependencies.

Mistake No. 10: They don't consider Murphy's Law.

Impact: Stuff happens, and IT gets surprised by it. Consequently, the project goes off-track while IT tries to clean up a mess it didn't anticipate.

The lack of planning caused the IT staffers to do more work than was necessary.

Solution: Perform a risk assessment as part of the project planning. With your team, brainstorm what could happen to slow or derail the project, to make it go over budget, or to prevent you from delivering the expected requirements. Then figure out ways you can mitigate those risks.

Mistake No. 11: They give short shrift to change management.

Impact: All the time, money and hard work that went into delivering a new IT-enabled capability can be for naught if users don't adopt the new technology.

Solution: Spend time up front during the project planning phase to consider where resistance to a project will manifest itself and ways to address it, says Métier's Clark. Identify the stakeholders whose jobs will be impacted by the new capability, adds Intellilink Solutions' Kondo, and plan how you'll communicate changes to their processes and workflows with them. Not all of the changes will be negative.

Mistake No. 12: Project schedules are incomplete.

Impact: Project team members don't know what is due when, which makes completing the project on time a challenge.

Solution: Clark says a quick way to come up with a schedule for a project is to determine all the activities involved in getting the project done (e.g. scoping, getting requirements, testing and implementing) and then attaching due dates to those activities based on the deadline for the project. Project management software can also help create schedules.

Communication Problems

Mistake No. 13: IT doesn't push back on unreasonable deadlines.

Impact: IT sets itself up to fail and gets a reputation for not being able to deliver projects on time.

Clarksays IT departments will scramble to accommodate project deadlines set by the CEO. But tampering with dependencies and with the plan only creates more problems that make delivering the project on time even more difficult, he says.

Solution: IT management has to explain to the CEO what it's going to take to meet that deadline in terms of cost and resources and has to get the CEO to choose between cost, scope and schedule, says Clark.

Mistake No. 14: They don't communicate well with project sponsors and stakeholders.

Impact: IT fails to deliver the expected requirements.

Solution: Project communications need to be catered to the audience, says Kondo. She sees misunderstandings about the scope of a project or a systems' requirements arise when IT departments hand over a spreadsheet to the business with thousands of lines describing the systems' functionality and specs. Because the business owners don't have time to look over such detailed technical documents, they ignore them.
