Introduction to Design Thinking

Core practices of IBM Design Thinking

Hills focus on big

(but attainable)

problems and

outcomes for

users (not just a

list of feature

requests)

Playbacks align your team,

stakeholders, and clients

around the user value you will

deliver

Sponsor Users help you

design experiences for

real target users, rather

than imagined needs

Potential future hill candidates for IMS

Cloud-Style

Provisioning

Anyone can provision

an IMS system in an on-

prem cloud with a

strategically aligned

configuration following

industry best practices in

less than 5 minutes.

Mobile

24x7 Database

Support

A DBA can use standard

database schema

creation and alteration

methods for a DB

without an application or

database outage in less

than two minutes.

Technical Foundation A collection of work comprising specific user requirements, which sets up for future

releases (e.g. driving down technical debt or introducing underlying architecture to

do “something new” in a future release)

A mobile system

administrator, can

promote, resolve conflicts,

and validate multiple

services to production

without having to

manually recreate each

service, thus reducing

deployment time from

hours to minutes.

Potential design hill 1: Cloud-style provisioning of an IMS system

7

Anyone can provision an IMS system in an on-prem cloud with a strategically

aligned configuration following industry best practices in less than 5 minutes.

Provision – “The act of providing or supplying something for use.”

This hill addresses the problem that too many steps and too much IMS knowledge

are required to complete this task today. The intent would be to focus on ease of

use, ultimately allowing someone with limited IMS knowledge to quickly provision

an IMS system for application development/test, maintenance, or other purposes.

Food for thought (Bluemix)


Corporation

___ An IMS system programmer can provision an IMS

TM/DB system using a web-based UI in less than 5 minutes. • Rapid and repeatable deployment of IMS TM/DB configurations on production systems

• Additional components (e.g. IMS Connect, ODBM) automatically part of provisioning process

• Sysprogs have full access to system for updating/adding/removing functions, features

___ A new IMS DBA can provision an IMS DB in a similar manner to other relational DBs using a

web-based UI in less than 5 minutes. • Rapid and repeatable deployment of IMS DB configurations

• Standard data definition language (DDL) interface to IMS DB

___ An application developer can provision an IMS TM/DB system for development and test

purposes using a web-based UI in less than 5 minutes.

• Rapid and repeatable deployment of IMS configurations on test and development systems

___ An application developer can deploy an application in IMS using a web-based

UI with limited knowledge of IMS. • DevOps lifecycle support

• Iterative development and test of applications

• Limited knowledge ~ Less than a year of experience with IMS

Potential design hill 2: 24x7 database support

This potential hill addresses the problem of having to take outages for most DB schema

changes. The intent would be to focus on the most common changes to eliminate the need

to take the DB offline during the process.

Assumptions

• Taking outages to make DB schema or PSB changes inhibits your ability to make

application changes in a timely fashion.

• An external online change has significant impact on end users.

• A system-managed quiesce of transactions and/or

applications for a short period of time is acceptable.

11

A DBA can use standard database schema creation and alteration methods for a

DB without an application or database outage in less than two minutes.


Corporation

24x7 database support hill statements

___ An application developer can make DB schema changes for all database types

dynamically in a single step without outages.

• Empowers application developers to roll out needed changes dynamically

• No ‘outage’ to running transactions

• Some changes might be enabled without need for an online reorganization

___ Any DBA can create an IMS DB schema change without IMS knowledge using a wizard

and deploy the change with no DB or application outage.

• The capability would be through an interface that a DB2 DBA might be familiar with.

• For instance, changes via DDL would be able to drive more dynamic changes (no

ACB, PSB or DBDGENs, no online change)

___ A DBA can modify a PSB and bring it online in less than 2 minutes.

• No PSBGEN, reorganization or external online change

• The IMS system would manage the quiesce of the program and related resources as

appropriate.

Potential design hill 3: Mobile

This hill responds to the needs of the mobile environment with

continued improvements in the IMS Mobile Feature Pack and

alignment with z/OS Connect across the IBM subsystems

A mobile system administrator, can promote, resolve conflicts, and

validate multiple services to production without having to manually

recreate each service, thus reducing deployment time from hours to

minutes.


Corporation

Potential technical foundation design hill

17

A collection of work comprising specific user requirements, which sets up for

future releases (e.g. driving down technical debt or introducing underlying

architecture to do “something new” in a future release)

The items for this potential hill are a sampling of specific user

requirements that we have explored and we are looking for your

feedback.


Corporation

___ Predictive analytics using SPSS: • An analyst can reduce fraudulent transactions by invoking predictive analytics directly from

the IMS application in real time.

• A data scientist can identify fraudulent transactions programmatically.

• Predictive analytics software can evaluate IMS transaction authenticity in real time.

___ Serviceability: • A customer can automatically collect problem documentation without intervention.

• IMS Support can begin problem diagnosis immediately.

___ Database fence: • A DBA can allow a DB to be updated by a selected online application while preventing

updates from all other applications without scheduling failures or modifying processing

options.

___ Workload quiesce: • A system programmer can quiesce all IMS resources related to an application package

without knowledge of all related resources.

• A DBA can schedule a workload quiesce without monitoring the process.

___ IMS Restart Lite • A sysprog can resolve database work for a failed IMS with a limited service IMS

without the cost of implementing an FDBR region.
