‘You don’t have a computer? But what do you do?’

The world has changed so radically since the invention of the PC that you wonder how you even functioned without things like email and cell phones. And it seems the world is going through another change now – moving from email communication and individual task management to transparent online collaboration.

Since the advent of social media, developers have been finding ways to make this technology work in the working world. And they’re succeeding. In many companies, email communication, file sharing and to-do lists are being replaced by online tools that keep everything in one place. Here are three of our favourites:

1. Dropbox

Dropbox is cross-platform cloud-storage and file-sharing software that allows multiple-user access to files and documents. It not only allows you to keep your documents automatically backed up to the cloud, but with its cross-platform functionality, you can also access it from your Windows PC, your Apple iPad, your Android smartphone – wherever you are.

Dropbox isn’t new. Many people initially used it as a tool to share large documents – which is still the case today. But did you know that Dropbox does much more?

These days you can automatically sync photos from your cell phone or Facebook account to Dropbox, find a stolen laptop by tracking your machine’s IP address in Dropbox’s security settings, host a website with DropPages, print files remotely, and collaborate easily with colleagues. Get enough space on Dropbox and you won’t even need a My Documents folder on your hard drive – you can keep all your working documents safely in the cloud.

2. Slack

Slack is making email obsolete. It’s a workplace chatroom on steroids - discussions are grouped by topic and files and conversations are searchable. It’s also easily integrated with a host of other platforms like Dropbox, Google Drive, RSS feeds, Twitter, Zendesk and our final favourite online collaboration platform, Asana.

3. Asana

Asana is an online and mobile task-management tool that allows members to: create deliverables within separate projects, add followers, assign tasks to those responsible, set due dates, conduct discussions and share documents. This makes Asana a reservoir for all current, past and upcoming work.

Not only does Asana keep projects transparent and easy to manage, but it makes it easier for individuals to keep track of their own deliverables. At envisionme.co.za, for instance, we’re not sure how we did things before Asana. And with well-known organisations like Uber and Mashable using Asana too, we’re not the only ones who feel this way.

Social media has changed everything. Online communication with people all over the world is easy and common. So why not take this technology into the workplace? These platforms (and many, many more) are mobile, transparent, collaborative and will probably make your job a little easier. What are you waiting for?
