Navigating Team Friction

Lara Hogan, Co-founder of Wherewithall

  • Teams go through Tuckman's Stages of Group Development

    • Forming: New state; team will have roughly-planned goals and objectives
    • Storming: Friction arises as team members start to learn how to work together (this is a normal and necessary part of forming a group)
    • Norming: Members start to resolve differences
    • Performing: Flow state; members start to become productive
    • A team can restart this process when there is new management, a new team structure and/or new team members
  • Friction is normal in early stages, but can act as a distraction and a team needs to resolve differences in order to move projects forward

Prerequisites

This all assumes you're Chrome [1]. I'm using Brave Browser [2], a privacy-focused Chrome fork, and it works well. I wouldn't be surprised if other Chrome forks work as well.

Creates an SVG string that can be used as a favicon across different Git branches. Actually getting this into the browser is sadly project-specific.
const { execSync } = require('child_process')
const { createHash } = require('crypto')
const invertColor = require('invert-color')
const branchName = execSync('git rev-parse --abbrev-ref HEAD')
const hash = createHash('sha256')
hash.update(branchName)
const color = '#' + hash.digest().toString('hex').substring(0, 6)
const invertedColor = invertColor(color, true)
