Microsoft Project

Microsoft Project is the perfect platform for medium and large companies. I do not recommend this software for small businesses, because all its functions in the work plans are high cost and this would cause the small business to not perform well in the use of MS Project in the long term. It is very easy to use software, it allows adding, modifying and eliminating all kinds of assignments and tasks for all employees, it allows monitoring the progress of all projects in real time and it also shows the gaps in the planned project. It has a very good performance, it does not take up many computer resources and all the information is stored in sync with the Office 365 service. It occasionally has crashing problems, but this is something that does not affect users as much.

Slack

It's great for keeping groups of people in touch and in sync, no matter the reason: a group of friends, a family, a small business, or a large business. My family even uses it to plan events, share funny pictures, or broadcast important family news. However, it's less appropriate for keeping contact between just two or three people, unless they're working on a complex project that could benefit from sectioning various conversations into specific channels.

Pros

Microsoft Project

  • It is part of Office365 subscription. The look and feel is similar to other tools like excel. Helps in creating project plans, Gantt charts, work break down structures etc.
  • Helps in resource allocation and tracking the projects. There is an option to use it to capture timesheets too.
  • Helps project managers in producing weekly status reports and integrates well with other collaboration tools like Skype, sharepoint etc.

Slack

  • Slack Channels for different groups of individuals for different initiatives.
  • It is very easy to sign up for and use as a tool - Intuitive.
  • The "Threads" feature is very helpful in NOT missing out any replies
  • Ability to Save convos that you might want to return to is very helpful
  • Screensharing with zero overhead
  • Connectivity with external vendors over slack

Cons

Microsoft Project

  • Seems overly complicated for users sometimes in using Project and its functionalities
  • Hard to share files for those folks who do not have MS Project, and then have to print out for them
  • Can be confusing since it looks and feels like MS Excel

  • Searching can be improved - right now it's ungrouped. Have to do a more detailed search, which will then narrow the results.. Grouping allow look ahead to see if the results are relevant. e.g. by DMs, channels.
  • Notifications dont work in sync at times for mobile and desktop. Also not working in sync when switching over to mobile once away from desktop. Not consistent there.

Slack works incredibly well and allows our whole remote-first company to work together from all around the World. The flexibility, ease of use and scalability of the solution means that we can continue to grow and make use of the team with a minimum of effort. I can see no obvious reasons why we would migrate to a different tool other than perhaps cost, but whatever savings would disappear in migration/setup time and the initial productivity loss.

Microsoft Project was for many years the reference tool when you were talking about project management software, even if it has some gaps. However, in the last several years, other tools emerged and covered those gaps and are getting more and more users. Microsoft needs to keep up with the trends as they did with adding Project Server. However, that needs a significant rework.

Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

I’m giving MS Project an 8 because in general this is a solid scheduling program. It’s definitely designed with the professional in mind, and they have done well preparing the program to integrate with their other Microsoft products. The program is a workhorse so if you have serious scheduling needs then I would highly recommend MS Project.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

Alternatives Considered

Microsoft Project

While many of the above tools are extremely well-versed, Microsoft Project's largest advantage comes from it being related to the largest business productivity company in the world. Project does have its sharing limitations - but regardless, offers one of the most robust tools in the market today. Microsoft Project is built with large-scale projects in mind but is more than up to the task for smaller projects as well. However, there are options available (especially cloud-based options) that may be more fitting for higher-level projects that do not require going into the weeds.

Slack

In comparison to WhatsApp Business, Slack is a better option. One reason could be that I work in a software development organization rather than a manufacturing or sales one. Slack's interface is more user-friendly than Discord's. Microsoft Teams has more integration options and features to keep all communications organized. We can share many types of data in various ways, not just text. It simplifies data management and allows users to personalize the app. It also facilitates and streamlines collaboration.

Return on Investment

Microsoft Project

  • Project saved me, as the project manager, countless hours of digging through tickets and schedules to plan everything out. It also saved me time in adjusting the project triangle as needed, since it does so much automatically.
  • It is costly, and since it requires extensive training to master, it's not just the high licensing cost that you need to take into account.
  • The reporting features - even just printing out Gantt charts - makes it far easier to communicate with stakeholders. That means less time for PMs doing all of this manually, and it means less follow-up questions and delays moving forward.

Slack

  • It brought improvements in the general communication of all my employees. Our company is medium-sized, and Slack allowed all sectors to have a much more complete interaction and can generate more constant planning.
  • During the COVID-19 problems, Slack was a piece of software that helped us stay connected as an online work team, without having to go to our work office.
  • The administration and planning of all areas of my company improved significantly.
