There are two reasons for your company to tackle a project.  The first is because there is an external motivator.  You need to complete a project for a client or for the public.  The second is an internal motivator.  You need to complete a project to enhance your operations, productivity or financial situation.  No matter what the reason, the potential projects must be researched and ranked, then finally planned and executed.

Below is a list of project tools and descriptions to help you record and track internal and external projects.  This list was compiled by eweek.com.

1.  Citrix Podio Tracks Leads, Team Tasks

Citrix's Podio platform comes with all the project-management features that enterprise users would expect to find, including tasks and meeting scheduling as well as the ability to track leads and keep an entire team informed. The service's best feature, however, might be its application marketplace, which provides tailor-made project management applications for different industries. Best of all, it's free for up to five employees. Pricing beyond that starts at $15 per employee per month.

2.  Basecamp Optimized for Mobile Users

Basecamp is one of the simplest applications in this roundup. The service allows companies to quickly create tasks and assign team members to them. It also includes an email alert system to notify employees of their tasks. Basecamp has also been optimized for mobile users, which comes in handy. The platform's service starts at $1 per day for up to 15 projects at once and 4GB of storage.

3.  Zoho Projects Platform Integrates Cloud Storage, Document Management

Zoho has been competing in the online-productivity space for years with several different applications. Still, its Zoho Projects platform might just be the best option. It includes full cloud-storage integration, as well as document management and full coordination of different projects. Its calendaring feature is also a winner. One of the nicest things about Zoho is that it's free for a single project. Its cheapest paid plan costs $199 per year.

4.  Planbox Tracks Progress

Planbox might not have the name-recognition of some of the other services in this roundup, but it's arguably one of the most capable. Chief among Planbox's features is something called the Storyboard, which pins items to a central location in the software and then can estimate progress, hours to completion, budget and more. Planbox is extremely high-powered, and is free for up to two employees. Its cheapest plan costs $20 per month.

5.  Milestone Planner Delivers Basic Project Management

Milestone Planner lacks some of the design features found in the other options, but can still help companies get work done in a timely fashion. The service allows managers to establish projects and tasks, track deadlines, track progress and create reports for executives. It's a simple applications solution, but at $9 per month, it's not so expensive.

6.  Smartsheet Focuses Heavily on Sales, Marketing, IT Management

Smartsheet is an interesting inclusion in this roundup because it's designed around the idea of appealing to certain industries, and not necessarily every type of company under the sun. The company's platform, which looks somewhat similar to a spreadsheet in terms of its layout, focuses heavily on marketing, sales and IT, and includes everything from planning and budgeting to keeping track of new hires. However, Smartsheet's pricing schedule is a little convoluted, and it costs $15.95 to start.

7.  Office 365 Does Project Management, Too

Microsoft doesn't necessarily bill Office 365 as a project-management platform, but it can very easily be turned into one. The company's cloud platform includes support for everything from creating and editing documents to collaborating on projects with Sharepoint. Plus, its Outlook integration is a welcome addition. Best of all, it costs just $5 per user per month.

8.  SugarSync Lets Users Collaborate Remotely

Don't let SugarSync's name fool you: While it's perhaps best known for offering cloud storage and synchronization across devices, the service is also quite capable at handling projects. In fact, it includes the ability for users to collaborate on projects remotely and set up a single-point billing system that can be managed from the Web. Pricing for three years starts at $55 per month.

9.  Salesforce Work Focuses on Sales--What Else?

Salesforce Work is unlike the other applications in this roundup because it focuses on one primary business—sales—and no other. Still, it works quite well. The offering allows users to track customer engagement, set up a plan for work and assign tasks to team members. The platform also allows companies to set up sales goals and measure performance. But it won't take long for the cost to shoot up; pricing is $10 per user per month.

10. Clarizen Does Hard-Core Project Management

Clarizen is easily the most powerful project management software in this roundup. The application can do just about everything. From budgeting to scheduling to setting up Gantt charts, the service has every last thing a company would need to track a major project. However, those features come at a price; pricing starts at $49.95 per user per month for service.
