Then, we don't need to do these two steps, the database administrator sends an email,

so I cut those two steps.

And then, the request is going to, again,

wait in the queue to be picked up again at the same time, 3 days.

Because we don't want to make any major change,

just simple change without impacting anything.

And then, the database administrator picks up the request and sets up the meeting

with the developer for additional information, so that's another 5 minutes.

So again, what's adding here is this 3 days, which is 4,400 minutes, and

then, the 5 minutes for the database administrator to set up the meeting.

Then, developer waits for the meeting, again 2 days, we're not making any change.

But then, after that, why don't we merge finalizing the requirements and

doing the actual work right there in that meeting?

So that if they have any additional question,

it could be resolved right there, and they can be just done with it.

So developer and database administrator meets to finalize the exact requirements

and works on the request in the meeting itself.

So in 45 minutes, instead of 30 minutes and 15 minutes,

they just finish the whole thing together.

So again, then you don't have to do these two steps separately.

So the value stream map will look something like this.

2 days to wait for the meeting, and then 45 minutes to get the work done.

So as you can see, we significantly simplified

the value stream mapping, or value stream map, or the process.

So let's see if it really helps in the process cycle efficiency.

So process cycle efficiency, again,

it's the value added time divided by total cycle time.

So in this case, the value added time is 10,

120, 5, and 45, so that totals up to 180.

And the total cycle time is all of these numbers and 2,400,

1,440 and 960, so that totals up to 4,980.

So the process cycle efficiency would be 180,

divided by 4,980, so that comes out to be 3.6%.

So as you can see, without making any major change,

without changing the wait time of 5 days or 3 days,

we were able to improve the process cycle efficiency by at least 1%,

so it's 3.6%, but can we improve any further?

I think we can.

So some of the things we can look at to improve this further

is why does it take this 5 days?

Can we reduce that time?

Can we reduce these 3 days wait time?

And can we reduce these 2 days of wait time?

So I think the next step could be to work on these three items, and

see if we can reduce those times, even by a day in each,

can significantly improve the process cycle efficiency.
